b For the powder putty, except that powder is directly determined for the soluble heavy metal, others are determined
according to the specified mixture ratio of the product after mixing the powder with water, adhesive or other liquids. If the
mixture ratio is certain range, water shall be determined after mixing according to the minimum mixture ratio of water
consumption while other liquids such as adhesive shall be determined after mixing according to the maximum mixture
ratio of the consumption.
5 Test Methods
5.1 Sampling
The product shall be sampled according to those specified in GB/T 3186.
5.2 Test methods
5.2.1 Volatile organic compounds content is tested according to those specified in
Appendix A of this standard. Test results of coating product are calculated according
to those specified in Article A.7.2 of Appendix A; those of putty product are calculated
according to those specified in Article A.7.1 of Appendix A.
Note. moisture content and density tests are omitted for all the putty samples.
5.2.2 Content of benzene series (benzene, toluene, ethylbenzene and
dimethylbenzene) is tested according to those specified in Appendix A of this standard.
The test results are calculated according to those specified in Article A.7.3 of
Appendix A.
5.2.3 Content of glycol ether and its esters (ethylene glycol monomethyl ether,
ethylene glycol monomethyl ether acetate, ethylene glycol ethyl ether, ethylene glycol
ethyl ether acetate and diethylene glycol butyl ether acetate) is tested according to
those specified in Appendix A of this standard. Test results are calculated according to
those specified in A.7.4 of Appendix A.
5.2.4 Content of free formaldehyde is tested according to those specified in
Appendix C of GB 18582-2008.
5.2.5 Content of soluble heavy metal (lead, cadmium, chromium and mercury) is
tested according to those specified in Appendix D of GB l8582-2008 and its results are
expressed in milligram of the soluble heavy metal containing in the film per kilogram.
For the powder putter, it is directly tested with the powder.
Note. content of soluble lead, cadmium, chromium and mercury in the treated test solution may be determined with
other appropriate analysis instruments, such as inductively coupled plasma atomic emission spectrometric
method (ICP-OES); operation and test are carried out according to relevant instructions of the instrument
manufacturer. Moreover, the adopted analysis instrument shall be indicated in the test report.
Appendix A
(Normative)
Test for Content of Volatile Organic Compound, Benzene
Series, Glycol Ether and Its Esters - Gas Chromatography
A.1 Scope
This appendix specifies test methods for the content of volatile organic compounds
(VOC), benzene series (benzene, toluene, ethylbenzene and dimethylbenzene),
glycol ether and its esters (ethylene glycol monomethyl ether, ethylene glycol
monomethyl ether acetate, ethylene glycol ethyl ether, ethylene glycol ethyl ether
acetate and diethylene glycol butyl ether acetate) in water based woodenware
coatings and water based putty.
A.2 Principle
After the sample is diluted, volatile organic compounds in the sample are separated
through the gas chromatographic analysis technology; after qualitative identification of
the measured compound, its content is tested by internal standard method.
A.3 Materials and reagents
A.3.1 Carrier gas. nitrogen, with purity greater than or equal to 99. 995%.
A.3.2 Gas. hydrogen, with purity greater than or equal to 99. 995%.
A.3.3 Combustion-supporting gas. air.
A.3.4 Auxiliary gas (septum purging and make-up gas). nitrogen of same nature
with the carrier gas.
A.3.5 Internal standard substances. compounds absent in the sample; the
compounds can be completely separated from other components on the
chromatogram. The purity is at least 99% (mass percent) or the purity is known. For
example. isobutanol, ethylene glycol butyl ether and diethylene glycol dimethyl ether.
A.3.6 Calibration compounds
In this standard, calibration compounds cover benzene, toluene, ethylbenzene,
dimethylbenzene, ethylene glycol monomethyl ether, ethylene glycol monomethyl
ether acetate, ethylene glycol ethyl ether, ethylene glycol ethyl ether acetate,
diethylene glycol butyl ether acetate, acetone, ethanol, isopropanol, triethylamine,
isobutanol, 1-butanol, propylene glycol monomethyl ether, dipropylene glycol
monomethyl ether, acetic acid n-butyl ester, dimethylethanolamine, methyl isoamyl
ketone, propylene glycol n-butyl ether, ethylene glycol butyl ether, 1,2-propylene
glycol, ethylene glycol, N-methyl pyrrolidone, dipropylene glycol n-butyl ether,
diethylene glycol monobutyl ether, propylene glycol phellyl ether, diethylene glycol
and ethylene glycol phellyl ether. Purity of the calibration compound is at least 99%
(mass fraction) or the purity is known.
A.3.7 Dilution solvent. organic solvent for diluting the sample; it doesn't contain any
substance interfering the test. The purity is at least 99% (mas...
