标准范围
ISO 16000-23:2009规定了评估吸附性建筑材料降低甲醛浓度的一般实验室试验方法。该方法适用于板材、壁纸、地毯、油漆制品和其他建筑材料。甲醛的吸附可以通过吸附、吸附和化学吸附来实现。通过测量吸附通量和单位面积饱和质量，评估材料降低室内空气中甲醛浓度的性能。前者直接指示材料在某一时间点的甲醛浓度降低性能；后者与产品保持这种性能的能力有关。ISO 16000-23:2009中规定的方法使用添加甲醛的送风来确定建筑材料在降低甲醛浓度方面的性能。甲醛的吸附特性在很大程度上取决于湿度。甲醛在空气中的稳定性不如其他挥发性有机化合物，因此必须单独测试。ISO 16000-23:2009基于ISO 16000-9中规定的试验箱方法。ISO 16000-11规定了待测材料的取样、运输和储存，以及试样的制备。ISO 16000-3规定了测定甲醛的空气取样和分析方法，这是完整程序的一部分。
ISO 16000-23:2009 specifies a general laboratory test method for evaluating the reduction of formaldehyde concentrations by sorptive building materials. This method applies to boards, wallpapers, carpets, paint products, and other building materials. The sorption of formaldehyde can be brought about by adsorption, absorption and chemisorption. The performance of the material with respect to its ability to reduce the concentration of formaldehyde in indoor air is evaluated by measuring sorption flux and saturation mass per area. The former directly indicates material performance with respect to formaldehyde concentration reduction at a point in time; the latter relates to the ability of a product to maintain that performance.The method specified in ISO 16000-23:2009 employs formaldehyde-spiked supply air to determine the performance of building materials in reducing formaldehyde concentrations. The characteristics of formaldehyde sorption depend greatly on humidity. Formaldehyde is less stable in air than other volatile organic compounds, so it has to be tested on its own.ISO 16000-23:2009 is based on the test chamber method specified in ISO 16000-9. Sampling, transport and storage of materials to be tested, and preparation of test specimens are specified in ISO 16000-11. Air sampling and analytical methods for the determination of formaldehyde are specified in ISO 16000-3, which is part of the complete procedure.
