2008);

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

This standard was proposed by and shall be under the jurisdiction of the

Ministry of Industry and Information Technology of the People's Republic of

China.

This standard replaces the standard previously issued as follows.

- GB 18582-2001, GB 18582-2008;

- GB 24408-2009.

Limit of harmful substances of architectural wall

coatings

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).

3 Terms and definitions

The following terms and definitions apply to this document.

3.1

Building

Spaces and entities constructed with building materials, which are used for

people to live and perform various activities.

[GB/T 50504-2009, definition 2.1.4]

Note. For example, residential building, office buildings, factories, warehouses,

shopping malls, stadiums, exhibition halls, libraries, hospitals, schools, airports, bus

stations, theaters, churches, etc.

3.2

Architectural wall coatings

Wall coating applied to the inner and outer surfaces of buildings based on

cement-based and other non-metallic materials (except wood materials).

3.3

Decorative panel coatings

A type of coating applied to panel-like products (except metal materials) with

functions of heat preservation and decoration on the surface of building walls.

Note. The decorative panels mainly include non-asbestos calcium silicate

board, non-asbestos fiber cement board, natural granite thin stone, glass,

porcelain board, ceramic board, etc.

3.4

Effect pigment

Usually flake pigments, in addition to providing color, which can also provide

some other properties, such as iridescence (formed by light due to

interference in a thin layer), optically variable color (color change, color jump,

color shading) or texture.

[GB/T 5206-2015, definition 2.91]

3.5

Volatile organic compound

VOC

Organic compounds participating in atmospheric photochemical reactions,

or organic compounds determined according to relevant requirements.

3.6

Volatile organic compound content

VOC content

The mass of volatile organic compounds present in the coating as measured

under specified conditions.

4 Product classification

This standard divides architectural wall coatings into. water-based wall coatings

and decorative panel coatings. Among them, water-based wall coatings are

divided into interior wall coatings, exterior wall coatings, putty; exterior wall

coatings are divided into effect pigments and other categories. Decorative panel

coatings are divided into water-based decorative panel coatings, solvent-based

decorative panel coatings; water-based decorative panel coatings are divided

into synthetic resin emulsions and other categories, whilst solvent-based
