序文
ISO (国際標準化機構) 国家標準化団体の世界的な同盟です (ISO会員団体). 国際規格の開発は通常、ISO 技術委員会を通じて行われます。. 技術委員会が設立された主題に関心を持つ各加盟機関は、その委員会に代表される権利を有する。. ISO と連携する国際政府および非政府組織もこの作業に関与しています。.

Draft international standards adopted by technical committees are circulated to member bodies for approval before being accepted as international standards by the ISO Council. They are approved under the ISO process, which requires at least 75 per cent approval from voting member bodies.

国際規格ISO 6503 was developed by the Technical Committee ISO/TC 35 塗料およびワニス用.

1 Scope and domain of application
This standard describes a flame atomic absorption spectrometry method for the determination of total lead in paints and related products.

This method is suitable for products with total lead content in the range of approximately 0.01 に 2% (m/m).

注記 – This method is also suitable for products with total lead content greater than 2 % (m/m), but should only be used if the accuracy does not exceed the appropriate value given in 7.2.

Two methods to deal with the test part are given. 紛争の場合, the dry ash method (Clause 4) shall be used as the method of adjudication.

To determine lead in test solutions, the dithiazole spectrophotometry specified in ISO 3856/1 May be used as an alternative method.
