This British Standard, having

been prepared under the

direction of the Electrotechnical

Sector Committee, was

published under the authority

of the Standards Committee and

comes into effect on

15 November 1999

© BSI 04-2000

ISBN 0 580 35146 7

This British Standard is the English language version of

BS CECC 299001:1999 It is identical with CECC 299001:1999

The UK participation in its preparation was entrusted by Technical Committee EPL/46, Cables, wires, waveguides, RF connectors and accessories for

communication and signalling, to Subcommittee EPL/46/2, RF connectors, which has the responsibility to:

— aid enquirers to understand the text;

— present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;

— monitor related international and European developments and promulgate them in the UK

A list of organizations represented on this subcommittee can be obtained on request to its secretary

by using the “Find” facility of the BSI Standards Electronic Catalogue

A British Standard does not purport to include all the necessary provisions of

a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

The requirements for Technology Approval of

manufacturers of electronic and electromechanical

components are given in CECC 00114-VI The

procedures for approval defined in that Rule of

Procedure require the manufacturer to have

available an appropriate Technology Approval

Schedule (TAS)

This schedule defines how the principles and

requirements of CECC 00114-VI are applied to

Electrical Connectors In particular it defines

minimum technical requirements which must be

met by a manufacturer writing a Technology

Approval Declaration Document (TADD) in

accordance with Annex D of CECC 00114-VI

1 General

1.1 Scope

This TAS specifies the terms, definitions, symbols,

quality system, test, assessment and verification

methods and other requirements relevant to the

design, manufacture and supply of Electrical

Connectors, in compliance with the general

requirements of the CECC system for electronic

components of assessed quality

1.4 Standard and preferred vValues

Technology approval allows values of ratings and characteristics to be selected to suit each customer, and so preferred values are therefore not

mandatory However, when there are no over-riding customer needs, it is recommended that the established preferred values for electrical connectors are utilised These may be found in the following publications:

1.5 Definitions

Definitions relevant to the technology, in addition to those given in CECC RP14-V, CECC 00401, IEC 50 and the relevant Generic/Sectional specifications, are given below:

3.3.2 Customer/user

When the manufacturer is designing a connector for

a specific customer requirement, the manufacturer

shall have a systematic method (e.g a

questionnaire) to unambiguously ascertain the

needs of the customer Where particular aspects of

the connector do not need to be precisely defined, the

manufacturer shall advise the customer of those

that are preferred See also subclause 6.5.2 of this

TAS and subclause 4.3 of ISO 9001.
