- ADD the terms and definitions of "building", "architectural wall coating", "decorative panel coating", "effect pigment" and "application condition" (see Chapter 3);

- MODIFY the definition of "volatile organic compound " and "volatile organic compound content " (see Chapter 3; Chapter 3 of GB 18582-2008);

- ADD the product classification (see Chapter 4);

- CHANGE the "water-based wall coating" to "internal wall coating", "water-based wall putty" to "putty", "free formaldehyde" to "formaldehyde content", "sum of benzene, toluene, ethylbenzene and xylene" to "total content of benzene series"; MODIFY the indexes of "VOC content", "formaldehyde content", "total content of benzene series"; DELETE the item and index of "lead Pb" in "soluble heavy metals"; ADD the item and index of "total Lead (Pb) content" and "total content of alkylphenol polyoxyethylene ether" (see Table 1; Table 1 of GB 18582-2008);

- ADD the "exterior wall coating" and its items and indicators (see Table 1);

- ADD the "decorative panel coating" and its items and indicators (see 5.2);

- MODIFY the test methods for the items "VOC content", "formaldehyde content", "total content of benzene series", "soluble heavy metal content" (see 6.2; 5.2 of GB 18582-2008);

- MODIFY the content of the test result judgment (see 7.2; 6.2 of GB 18582-2008);

- MODIFY the contents of the packaging mark (see Chapter 8; Chapter 18 of GB 18582-2008);

- DELETE the coating safety and protection (see Chapter 8 of GB 18582-2008);

- ADD the implementation of standards (see Chapter 9).

1 Scope

This standard stipulates the product classification, requirements, test methods, inspection rules, packaging marks, standard implementation related to the allowable limits of substances harmful to humans and the environment in architectural wall coatings.

This standard is applicable to all kinds of architectural wall coatings that are directly painted on site and factory-applied to decorate and protect the inner and outer surfaces of buildings based on cement-based and other non-metallic materials (except wood materials).
