Indoor decoration materials solvent wood coatings of harmful substance in limits The GB18581-2001 1, scope This standard stimulates the indoor decoration use lacquers class, polyurethane lacquer kind and alkyd lacquer kind wood coatings of harmful substances allow limited the technical requirements, experiment method, inspection rule, packing signs, safety coating and protection, etc. This standard applies to all indoor decoration with solvent wood coatings, other resin types and other purposes with the indoor decoration solvent-based coating can consult use. This standard does not apply to waterborne wood coatings. 2 and normative reference documents The following documents by this standard, the terms of reference and become the standard terms. Every note date reference documents, its all subsequent revision single (not including errata content) or revised edition is applicable to this standard, however, an agreement under this standard encourage the parties to investigate whether can use these documents the latest edition. Anyone who doesn't note date reference documents, its newest edition applies to this standard. GB/T 1250 to 1989 limit numerical representation methods and determination method GB tackifier had - 1982 (1989) coating product sample of his pupils about 1515: neq ISO (1974) GB/T 6682-1992 analysis lab water specifications and test method (neq ISO 3696:1987) GB/T 6750-1986 paint and varnish density measurement (eqv ISO 2811:1974) GB/T 6751-1986 paint and varnish volatiles and not volatiles determination of his pupils about 1515: eqv ISO (1973) GB/T moves 9750-1998 coating product packaging symbol GB/T 9758.1-1988 paint and varnish "soluble" metal content determination of part 1: the determination of lead by flame atomic absorption spectrometry and double dithizone spectrophotometry (idt ISO 3856.1:1984) GB/T 9758.4-1988 paint and varnish "soluble" metal content determination of part 4: cadmium content is determined by flame atomic absorption spectrometry and polarographic (idt ISO 3856.4:1984) GB/T 9758.6-1988 paint and varnish "soluble" metal content determination of section 6: paint liquid part chromium total content is determined by flame atomic absorption spectrometry (idt ISO 3856.6:1984) GB/T 9758.7-1988 paint and varnish "soluble" metal content determination of the first seven parts: paint pigment part and the water can dilute liquid portion of paint the mercury content determination of no flame atomic absorption spectrometry (idt ISO 3856.7:1984) GB/T 18446-2001 gas chromatography was developed for the determination were carbamate prepolymer and coating solution in the toluene diisocyanate not reaction (TDI) monomer Three, requirements Products should comply with the table 1 technical requirements: Item mesh limited quantity value of polyurethane paints lacquers kind of alkyd paints Volatile organic compounds (VOC) a / (g/L more than 750 luster (60 °) p 80. 600 550 Sheen (60 °) < 80. 700 Benzene b acuities 0.5 Toluene and xylene, more than 45 40 10 combined b Free toluene diisocyanate (TDI) c acuities 0.7 Heavy metal (limited to paint) / (mg/kg) acuities Soluble lead 90 Soluble cadmium 75 Soluble chromium 60 Soluble mercury 60 According to a prescribed ratios and dilute products after mixing ratio determination. Such as diluent use for a range, should according to the recommended maximum amount of diluted diluted were determined. B if the product stipulated the dilution proportion or product two-component or more components by respectively composed, should determine thinner and various components, then press the content of the product mix ratio prescribed calculated the total coating. Such as diluent use for a range, should according to the recommended maximum amount of diluted calculated diluted. C such as polyurethane lacquer kind stipulated the dilution proportion or two-component or more components by composed, should determine first curing agent (including toluene diisocyanate pre-polymer), then press the content of the product mix ratio prescribed calculated the total coating. Such as diluent use for a range, should according to the recommended minimum dilution quantity to calculate. 4, test method 4.1, sampling Products, according to GB/T tackifier had - 1982 (1989) on the provisions of sampling. Samples are divided into two, a sealing preservation, another copy with samples as inspection. 4.2, volatile organic compounds (VOC) was measured 2, the sample mix of GB/T, 6751-1986 determination coating volatiles quality score (V), test conditions: (105 + 2) ℃, maintain 3h. Mix out, the sample of GB/T after 1986 determination - 6,750.00 usd density (ρ), coating of testing temperature for (23 + 2) ℃. 4.2.3 and content of volatile organic compounds and press type calculation: VOC = V x ρ x 103........................ (1) Type: VOC - coatings volatile organic compounds content, the unit is grams per litre (g/L); V - coating volatiles quality score; ρ - coatings in (23 + 2) ℃, the un
