???????Standardization, principles, scope,
faces, objevtives and benefits
- Standardization or standardisation is the process
of developing and agreeing upon technical
standards. - A standard is a document that establishes uniform
engineering or technical specifications,
criteria, methods, processes, or practices. - Some standards are mandatory while others are
voluntary. - Voluntary standards are available if one chooses
to use them.
2- Some are de facto standards, meaning a norm or
requirement which has an informal but dominant
status. - Some standards are de jure, meaning formal legal
requirements. - Formal standards organizations, such as the
International Organization for Standardization
(ISO) or the American National Standards
Institute, are independent of the manufacturers
of the goods for which they publish standards. - The goals of standardization can be to help with
independence of single suppliers
(commoditization), compatibility,
interoperability, safety, repeatability, or
quality.
3Usage
- Standardization is the process of establishing a
technical standard, which could be a standard
specification, standard test method, standard
definition, standard procedure (or practice),
etc. - The existence of a published standard does not
necessarily imply that it is useful or correct.
4- Just because an item is stamped with a standard
number does not, by itself, indicate that the
item is fit for any particular use. - The people who use the item or service
(engineers, trade unions, etc) or specify it
(building codes, government, industry, etc) have
the responsibility to consider the available
standards, specify the correct one, enforce
compliance, and use the item correctly.
Validation of suitability is necessary.
5- In the context of social criticism and social
sciences, standardization often means the process
of establishing standards of various kinds and
improving efficiency to handle people, their
interactions, cases, and so forth. - Examples include formalization of judicial
procedure in court, and establishing uniform
criteria for diagnosing mental disease.
6- Standardization in this sense is often discussed
along with such large-scale social changes as
modernization, bureaucratization, homogenization,
and centralization of society. - In the context of business information exchanges,
standardization refers to the process of
developing data exchange standards for specific
business processes using specific syntaxes.
7- These standards are usually developed in
voluntary consensus standards bodies such as - the United Nations Center for Trade Facilitation
and Electronic Business (UN/CEFACT), - the World Wide Web Consortium W3C, and
- the Organization for the Advancement of
Structured Information Standards (OASIS).
8- In the context of customer service,
standardization refers to the process of
developing an international standard that enables
organizations to focus their attention on
delivering excellence in customer service, whilst
at the same time providing recognition of success
through a 3rd Party organization, such as British
Standards Institution (BSI).
9- The International Customer Service Standard
(TICSS) has been developed by The International
Customer Service Institute (TICSI) with the
objective of making it the cornerstone global
standard of customer service. - This standard has the status of an independent
standard, managed by The International Customer
Service Institute.
10- Standards can be
- de facto standards which means they are followed
by informal convention or dominant usage. - de jure standards which are part of legally
binding contracts, laws or regulations. - Voluntary standards which are published and
available for people to consider for use - In general, each country or economy has a single
recognized National Standards Body (NSB). - Examples include ABNT, ANSI, AENOR, BSI, DGN,
DIN, IRAM, JISC, KATS, SABS, SAC, SCC, SIS, SNZ.
An NSB is likely the sole member from that
economy in ISO.
11- NSBs may be either public or private sector
organizations, or combinations of the two. - For example, the three NSBs of Canada, Mexico and
the United States are respectively the Standards
Council of Canada (SCC), the General Bureau of
Standards (Dirección General de Normas, DGN), and
the American National Standards Institute (ANSI).
- SCC is a Canadian Crown Corporation, DGN is a
governmental agency within the Mexican Ministry
of Economy, and ANSI and AENOR are a non-profit
organization with members from both the private
and public sectors.
12- The determinates of whether an NSB for a
particular economy is a public or private sector
body may include the historical and traditional
roles that the private sector fills in public
affairs in that economy or the development stage
of that economy. - Many specifications that govern the operation and
interaction of devices and software on the
Internet are in use. - To preserve the word "standard" as the domain of
relatively disinterested bodies such as ISO, the
W3C, for example, publishes "Recommendations",
and the IETF publishes "Requests for Comments"
(RFCs).
13- These publications are sometimes referred to as
being standards. Drafts and working documents
should not be considered as formal published
standards. - In a military context, standardization can be
defined as The development and implementation of
concepts, doctrines, procedures and designs to
achieve and maintain the required levels of
compatibility, interchangeability or commonality
in the operational, procedural, material,
technical and administrative fields to attain
interoperability.
14- There are at least four levels of
standardization - compatibility,
- interchangeability,
- commonality and
- reference.
- These standardization processes create
compatibility, similarity, measurement and symbol
standards.
15- Techniques
- There are typically four different techniques for
standardization - Simplification or variety control
- Codification
- value engineering / value analysis
- Statistical process
- Other uses
- In statistics, standardization refers to
conversion to standard scores. - In test theory, standardization refers to
measurements or assessments conducted under
exact, specified, and repeatable conditions.
16- In supply chain management, standardization
refers to approaches for increasing commonality
of either part, process, product or procurement. - Such change will enable delayed making of
manufacturing or procurement decisions, thus
reducing variability found in having many
non-standard components. - From a New institutional economics point of view,
standardization process starts with a social
problem known as "coordination dilemma". - Standards, as "voluntary norms", serve to
facilitate the resolution of coordination
dilemmas and realize mutual gains then standard
refer also to a kind of social dilemma solution.
17- Types
- Types of standardization process
- Emergence as de facto standard tradition, market
domination, etc. - Written by a Standards organization
- in a closed consensus process Restricted
membership and often having formal procedures for
due-process among voting members - in a full consensus process usually open to all
interested and qualified parties and with formal
procedures for due-process considerations. - Written by a government or regulatory body
- Written by a corporation, union, trade
association, etc
18EUROPEAN FOOD STANDARDIZATION
- CEN, (Committee European de Normalisation) the
European Committee for Standardization, draws up
voluntary technical specifications to help
achieve the the Single Market in Europe,
promoting the welfare - ELEMENTS FOR A CEN STRATEGY AND ACTION PLAN
- Agricultural and food standardization has become
a reality at national and international level
since a long time.
19(No Transcript)
20- European food standardization has also become a
reality in this field since 1988 and may receive
a new impetus under the pressure of safety
necessities resulting from the establishment of
the European Food Safety Authority and the new
European regulation on food safety - It is one priority of the CEN Business Plan. The
outline and prospects of European Food
standardization were reported to the CEN
Administrative Board of 26-27th March 2001 (CEN
CA N 1242-2001-03-16). - A CEN Strategy and action plan is now proposed to
the CEN Technical Board taking into account the
experience of CEN and the new opportunities at
European and international level.
21- The document will present the following issues
- The ongoing work of CEN (existing European
standards, actions undertaken, work programmes) - The elements of a CEN Strategy at national,
European and international level - A proposal for an action plan for the short term
concerning the CEN National Members, CMC, ISO and
the Codex Alimentarius.
22I - THE ONGOING WORK OF CEN
- Since 1988 CEN produced more than 266 European
standards in the food sector developed by now 7
Technical Committees and 2 sub-sectors, mainly
for methods of sampling and analysis1. European
standardization supports European legislation
(e.g. - ENs based on EC mandates for materials and
articles in contact with food, for - irradiated food) and contributes to the quality
and the safety of food.
23- CEN also develops European standards for
specifications as shown by EN 131882000 for
vinegar and EN 131892000 for acid acetic. - A part of these standards are EN ISO
- standards under the Vienna Agreement (10 to
100). - European standards cover a big part of the food
chain from the food producer to the food
processor and address the consumer interests.
24- On 10 October 2000 CEN organized a seminar on
food safety and European standardization in order
to identify the European food industry problems,
needs for and use of voluntary tools. - CEN can assist as a service provider to
facilitate the European initiatives (e.g.
analytical methods, or more). - The industry and the food authorities have also
to express their needs to CEN.
25- The main outcomes of the seminar were the
awareness of the outside world on the useful
contribution of European standardization to food
safety and therefore a better visibility of CEN. - It was used as a basis for further discussions
with the European Commission and European
Parliament. - CEN is now working on specific projects in the
field of food standardization new - technologies (GMOs2), rapid test methods at low
cost (microbiology), animal feeding - stuffs (new mandate from DG Sanco/Enterprise
M/315 in co-operation with CEMA3),
26- cereals (new CEN Technical Committee 338
established since October 2001) - and traceability of fish (development of a CEN
Workshop agreement-CWA (http//www.cenorm.be/stand
ardization/tech_bodies/workshop/otherthanICT/ws8.
htm). - Since 2000 the White Paper on food safety (COM
(99) 719) presented by the European Commission,
and now the regulation on the European Food
Safety Authority and food safety (Regulation (EC)
N 178/2002 of 28 January 2002 JOCE L 31
1/02/2002) gave the opportunity to CEN to offer
its support
27- Since 1999 CEN has followed the discussions of
the Kangaroo Group composed of Members of the
European Parliament, Commission, Council and
industry, by - presenting the European standardization in the
food area and participating in - meetings where European food law is concerned
- The development of European food standardization
is one of the priority actions of CEN.
28- The development of European food standardization
implies the organization of the awareness of CEN
work in this field (e.g. December 2001 and June
2002 issues of the CEN Networking on food and
materials in contact with food -http//www.cenorm.
be/news/newsletter.htm), - a general recognition of its wide possibilities
(test methods, specifications, quality,
guidelines) and its involvement in the ongoing
international work of the Codex Alimentarius.
29- On proposal of the European Commission the Codex
Alimentarius Commission adopted the five CEN
methods for the detection of irradiated food as
General Codex Methods for the Detection of
Irradiated Foods4 at its 24th session of 2-7 July
2001 in Geneva. - The Codex Alimentarius Commission also revoked
the European Regional Standard for vinegar
(http//www.codexalimentarius.net/cac24/alinorm014
1/bodye.htm).
30- The work programme of CEN in the field of food
covers now more than 410 work items and will
increase with the work of TC 338 Cereals and
cereals products and TC 327 Animal feeding
stuffs based on mandate M/315 on animal feeding
stuffs. - CEN is aiming the recognition of the European
Commission supporting areas of standardization
where CEN can assist the European legislation.

32II- ELEMENTS FOR A CEN STRATEGY
- The development of European standardization can
benefit from an agreed strategy resulting from
initiatives taken by the CEN National Members and
CMC at European and international level. - Many CEN National Members have already developed
national standards (analytical methods or
specifications) for agricultural and food
products, as well as in the field of food
hygiene. - CEN National Members supported CEN via the
adoption of standards and the important progress
of the CEN work programme for food.
33- AFNOR, DIN and NEN are the most interested CEN
National Members in the development of European
food standardization. - CEN National Members can take initiatives and
make proposals to CEN which can be part of the
CEN Strategy both at European and international
level.
341. Elements for a CEN strategy at European level
- European standards already contribute to the
quality and the safety of food (e.g. irradiated
food, aflatoxins, listeria mycotogenes,
genetically modified organisms). - Initiatives can result from the development of
the European legislation for the safety of food
and the reference to European standards.
35- The European Food Safety Authority and general
principles of food law Regulation (EC) N178/2002
of the European Parliament and of the Council of
28 January 2002 on the general principles and
requirements of food law and the European food
Safety Authority- OJEC L N31 2002-02-01 p 1 - The European Food Safety Authority is entrusted
with a number of key tasks such as independent
scientific advice on all aspects to food safety,
communication and dialogue with consumers on food
safety and health issues as well as networking
with national agencies and scientific bodies.
36- The tasks of the authority essentially
concentrate on risk assessment and risk
communication. - Risk management - including legislation and
control - remains the responsibility of the
Commission. - It is proposed that CEN will establish a formal
co-operation with the European Food Safety Agency
when operating in 2002.
37- The Community principle has been to move away
from product specific requirements to horizontal
legislation covering broad aspects as food
additives, contaminants, labelling, etc. - The legislation has in certain sectors been
linked to the results from international
harmonization works as that of CODEX
Alimentarius, including regional standards (EC
Regulation 178/2002 Art 13- International
standards). - In the field of industrial products the
principles of the New Approach has been applied.
38- In the food sector this has been a non-issue and
the food authorities have not been prepared to
reduce their national inspections/control systems
and deregulate. - It is not politically realistic to assume that
the New Approach principles will be accepted as
such in the food sector. - However the question remains if there are
elements which could be taken over by the food
sector. - It would be logical to enter into a dialogue with
the Commission, industry and the National
Standards Bodies to identify possible elements.
39- Development of European standards in the food
sector - European Food Directives/new Regulation will
lead to an increased need for - - common validated analytical methods in order
ensure necessary comparison of test results - - developing sampling methods
- - methods for confirmation of test results (based
on the general provisions of the EN 45 000 series
of standards) and, - - guidance documents based on the new regulation
on hygiene (Hazard analysis and critical control
points).
40- The Joint Research Centre (Food products and
consumer goods Unit- Ispra) provides - validated methods which serve the various CEN
working groups (GMOs, mycotoxins, - materials in contact with food). Reference to
European standards is already used by - the Commission for the official control of
foodstuffs, and some contaminants (see - Annex). The European Commission, DG SANCO, also
provided some information on
41- European standardization in the field of the
detection of irradiated foods - http//europa.eu.int/comm/food/fs/sfp/fi07_en
.htlm) and - materials in contact with food
(http//europa.eu.int/comm/food/fs/sfp/food_contac
t/index_en.htlm- see practical - guide, chap III CEN).
- The European Commission makes use of European
Standardization when needs are identified on a
casual basis. - It would be necessary to broaden the dialogue
with the European Commission including a wider
range of possible interested parties.
422. Elements for a CEN strategy at international
level
- CEN policy with the International Standardization
Organization (ISO) is based on the Vienna
Agreement, on a case by case basis, and there is
a need for evaluation of ISO standards in view of
their enhancement to European standards (e.g. ISO
151612001 - Guidelines on the application of ISO 90012000
for the food and drink industry). - Around 500 ISO standards were already published
for a wide range of agricultural food products
mainly prepared by ISO TC 34 Agricultural food
product (methods of analysis, cereals, fruits
and derived products, butter, ice cream, spices
and condiments, tea, coffee, cocoa).
43- At international level, the European Commission
and CEN National Members via the national
governmental delegations can propose European
standards to the Codex Alimentarius Commission. - AFNOR and DIN participate in national delegations
of some Codex Committees (Food Additives and
contaminants, methods of analysis and sampling,
Codex Alimentarius Commission). - On behalf of DIN the German delegation
- proposed to the Codex Committee on food
additives and contaminants (Rotterdam-11-15 March
2002) to endorse as Codex methods European
standards elaborated by CEN TC 275 (CX/FAC 02/31
Add.1).
44- Since some years TC 275 has participated
informally to the Inter-Agency meetings (IAM),
preceding the meetings of Codex Committees on
methods of analysis and sampling. - Taking into account the growing interest for
European standards at this level, it is necessary
for CEN to establish a formal contact with the
Codex Alimentarius. - CEN can also participate in EC initiatives for
international co-operation (e.g. - ASEM/Asiatic countries and future food issues).
45- III PROPOSAL FOR AN ACTION PLAN
- An action plan is proposed taking due account of
already ongoing CEN activities in - the field and the framework strategy as shown
before. The aim is to complete a - process which started in 1988 which should lead
CEN to optimize its existing work - and standards as well as to offer a full set of
standards. The following action plan is - proposed
46- National Standards Bodies are invited to
consult nationally on possible projects - and to report to CMC by December 2002. Standards
and guides on food hygiene - should be considered as a source of possible
projects for CEN. - CMC takes up a broad consultation of the
European Commission on possible - references to European standards or projects to
assist EU Regulation. - CMC will propose a co-operation with the
European Food Safety Authority by end - 2002 subject to a possible formal agreement in
2003.
47- CMC organizes a survey with major stakeholders
in the process to inquire on - possible assistance from standardization in the
food chain (food industry, retailers, - and consumers) by end 2002.
- National Standards Bodies are invited to make
proposals to CMC on the basis of - ISO TC 34 standards and work programme (and
possible others like ISO TC 47 ) - by December 2002 in order to prepare a plan for
launching PQs on ISO standards - in the framework of the Vienna Agreement.
- CMC will initiate a co-operation with the Codex
Alimentarius by end 2002 .subject - to a possible formal agreement and request for
observer status in 2003.
48- CMC will prepare a web site on European food
standardization by end 2002 with - the view to provide a global information on the
role of standardization - organizations in relation to the food area in
2003. - CMC will report to BT on the progress of
actions by March 2003 subject to a final - report to BT by end 2003.
