标准范围

ISO 16000-24:2009规定了一种通用实验室试验方法，用于评估吸附性建筑材料对挥发性有机化合物（VOC）（甲醛除外）浓度的降低。这种方法适用于板材、壁纸、地毯、油漆制品和其他建筑材料。VOCs（甲醛除外）的吸附可通过吸附、吸收和化学吸附实现。通过测量每面积的吸附通量和饱和质量，评估材料降低室内空气中VOCs（甲醛除外）浓度的能力。前者直接表示材料在某一时间点降低挥发性有机化合物方面的性能；后者与保持该性能的能力有关。甲醛已被排除在ISO 16000-24:2009之外，因为它很难作为空气中的稳定标准。ISO 16000-24:2009基于ISO 16000-9中规定的试验室方法。ISO 16000-11中描述了待测材料的取样、运输和储存以及试样的制备。ISO 16000-3中描述了测定羰基化合物（甲醛除外）的空气取样和分析方法，ISO 16000-6和ISO 16017-1中描述了挥发性有机化合物。

ISO 16000-24:2009 specifies a general laboratory test method for evaluating the reduction in concentration of volatile organic compounds (VOCs) (except formaldehyde) by sorptive building materials. This method applies to boards, wallpapers, carpets, paint products, and other building materials. The sorption of VOCs (except 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 VOCs (except formaldehyde) in indoor air, is evaluated by measuring sorption flux and saturation mass per area. The former directly indicates material performance with respect to VOC reduction at a point in time; the latter relates to the ability to maintain that performance.Formaldehyde has been excluded from ISO 16000-24:2009 because it is difficult to obtain as a stable standard in air.ISO 16000-24:2009 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 described in ISO 16000-11. Air sampling and analytical methods for the determination of carbonyl compounds (except formaldehyde) are described in ISO 16000-3, and those of VOCs are described in ISO 16000-6 and ISO 16017-1.
