Foreword

This document (EN 14362-1:2012) has been prepared by Technical Committee CEN/TC 248 “Textiles and textile products”, the secretariat of which is held by BSI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2012, and conflicting national standards shall be withdrawn at the latest by August 2012.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14362-1:2003, EN 14362-2:2003. EN 14362 is composed of the following parts:

EN 14362-1, Textiles — Methods for determination of certain aromatic amines derived from azo

colorants — Part 1: Detection of the use of certain azo colorants accessible with and without extracting the fibres; EN 14362-3, Textiles — Methods for determination of certain aromatic amines derived from azo

colorants — Part 3: Detection of the use of certain azo colorants which may release 4-aminoazobenzene. The following is a list of technical changes since the last edition:

Part 2 of EN 14362 has been integrated into Part 1. This is mainly reflected in:

changes to Clause 4 "Principle";

insertion of a new Clause 8 "Test specimen sampling and preparation"; insertion of a new Subclause 9.1 "Colorant extraction for disperse dyes";

insertion of a new Subclause 9.2 "Textiles dyed with dyes other than disperse dyes";

addition of Annex D (informative) "Explanatory table of dyestuffs used in various textile materials".

Addition of Annex F (normative) "Colorants - Methods for determination of certain aromatic amines"; The calculation, previously Annex B (normative) has been moved to Subclause 9.6.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Bel …… 此处隐藏：2935字，全部文档内容请下载后查看。喜欢就下载吧 ……
