介绍
ISO标准 (国际标准化组织) 是国家标准机构的全球联盟 (ISO 成员机构). 国际标准的制定通常通过ISO技术委员会进行. 每个对已设立技术委员会的主题感兴趣的成员机构都有权派代表参加该委员会. 与 ISO 联络的国际政府和非政府组织也参与了这项工作. ISO 与国际电工委员会密切合作 (恒温恒湿试验箱) 关于电气标准化的所有问题.
技术委员会通过的国际标准草案将分发给各成员机构进行投票. 作为国际标准发布需要至少 75% 成员机构数量.
国际标准ISO 12040 由 ISO/TC 技术委员会制定 130, Graphic Technology.

介绍
The method described in this standard for assessing light resistance using blue wool references is technically consistent with the method given in ISO 2835. 然而, according to the latter, natural light should be used to obtain a valid evaluation of light resistance. This standard describes accelerated test methods by specifying light sources and filters for daylight simulation and by exposing test samples to artificial sunlight.
此外, the international standard is partially consistent with ISO 105-B02. For more information on equipment and test methods, ISO 105-B02 is recommended as a reference.
ISO标准 12040-1997 – Printing technology – Assessment of light resistance of printed matter and printing inks using filtered xenon arc lamps
1 范围
This standard specifies a method for evaluating the light fastness of printed matter and printing inks by giving
– General test requirements for printed matter;
– Special test requirements for inks.
This standard applies to all printing substrates, such as paper, 纸板, 金属 (thin metal sheets and sheets) and plastic film, as well as to all printing processes.
