scope:

This Standard specifies an accelerated test method for assessing the fastness, using artificial light, of coloured anodic oxidation coatings (hereafter referred to as the "coloured coatings") on products of aluminium and its alloys (hereafter referred to as the "products").

NOTE 1 Accelerated testing for determination of the light fastness of coloured coatings has two methods: light-fastness test mainly using visible light and ultraviolet light-fastness test mainly using ultraviolet light. This Standard specifies the former test method.

NOTE 2 Accelerated testing is suitable as a quality-control test of coloured coatings on products whose light-fastness number has already been established by means of outdoor exposure testing under conditions comparable to actual service.

NOTE 3 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 2135 : 2010 Anodizing of aluminium and its alloys - Accelerated test oflight fastness ofcoloured anodic oxidation coatings using artificial light (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.

WARNING Persons using this Standard should be familiar with normal laboratory practice. This Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices.

Because the lights emitted from the emission part of the ultraviolet light carban-arc lamp type light fastness testing machine contain a large amount of ultraviolet rays, when observing the inside of a testing tank by necessity during the test operation, great care shall be taken to safety by using spectacles of ultraviolet insulating glass etc.
