Foreword
All the technical contents of this standard are mandatory.
The standard replaces GB 18581-2001 “Indoor decorating and refurbishing
materials - Limit of harmful substances of solvent based coatings for
woodenware”.
As compared with GB 18581-2001, main technical changes of this standard
are as follows.
- DEFINE the scope of application as the polyurethane, nitro and alkyd
solvent based coatings (including primer and finish) for woodware AND the
solvent based putty for woodware for the purposes of indoor decorating and
refurbishing and factory coating;
- In the scope of application, ADD the solvent based putty for woodware;
and SPECIFY the limit of harmful substance;
- In the scope of application, SPECIFY clearly that it is not applicable to the
radiation curing coatings and unsaturated polyester putty;
- In the nitro-based paint, ADD the methanol content control items;
- DEFINE the total content control item of toluene and xylene as the total
content control item of toluene, ethylbenzene and xylene;
- CHANGE the original standard free toluene diisocyanate (TDI) content
control item to free diisocyanate (TDI, HDI) total content control item;
- ADD the halogenated hydrocarbon content control item;
- MAKE the limits of the total content of volatile organic compounds, free
diisocyanate (TDI, HDI) total content, total content of toluene,
ethylbenzene and xylene, and the benzene content in the coating more
stringent.
- ADD the definition of volatile organic compounds and volatile organic
compounds content; ESTABLISH the corresponding test methods;
- ESTABLISH the test methods of methanol and halogenated hydrocarbon
content;
- MODIFY and IMPROVE the benzene, toluene, ethylbenzene and xylene
content test method;
Indoor decorating and refurbishing materials - Limit of
harmful substances of solvent based coatings for
woodenware
1 Scope
This standard specifies the allowable limit value requirements, test methods,
inspection rules, packaging marks, coating safety and protection, etc., of the
human and environmental harmful substances in polyurethane, nitro and alkyd
solvent based coatings of woodware AND the solvent based putty of
woodware for indoor decorating and refurbishing purposes.
This standard applies to the polyurethane, nitro and alkyd solvent based
coatings (including primer and finish) for woodware AND the solvent based
putty for woodware for the purposes of indoor decorating and refurbishing and
factory coating. It does not apply to radiation curing coatings and unsaturated
polyester putty.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Volatile organic compounds (VOC)
It refers to, at the standard atmospheric pressure of 101.3 kPa, any organic
compound having an initial boiling point of less than or equal to 250 °C.
3.2
Volatile organic compounds content
It refers to the content of the volatile organic compounds as obtained
through testing the product by the specified test methods.
3.3
Polyurethane coatings
It refers to a kind of coating for which the main film forming substance is the
polyamine (methacrylic acid) ester resin which is formed by the reaction of
polyisocyanate and an active hydrogen-containing compound.
3.4
Nitrocellulose coatings
It refers to a kind of coating for which the main film forming substance is the
