4、 This British Standard is the official English language version of EN ISO 105-J02:1999. It is identical with ISO 105-J02:1997. It supersedes method J02 of BS 1006:1990. The UK participation in its preparation was entrusted to Technical Committee TCI/81, Colour fastness and colour measurement, which

5、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 i

6、n the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their correspondin

7、g European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue
