ISO 15011-5:2011规定了获取焊接、切割、预热和矫直金属时产生的热降解产物信息的程序,金属采用完全或部分由有机物质组成的涂层进行处理,例如车间底漆、油漆、油、蜡和焊缝间材料,如粘合剂和密封剂。它主要针对执行此类程序的测试实验室。生成的数据可供涂料制造商用于提供安全数据表中包含的信息,也可供职业卫生学家用于识别在风险评估和/或工作场所暴露测量中具有重要意义的热降解产品。这些数据不能直接用于估计工作场所暴露。
ISO 15011-5:2011适用于部分或全部由有机材料组成的所有涂层,这些材料可在焊接和切割、预热和矫直过程中被加热至产生热降解产物的温度,并且这些降解产物不明显。
ISO 15011-5:2011 specifies procedures for obtaining information about thermal degradation products generated when welding, cutting through, preheating and straightening metal treated with coatings composed wholly or partly of organic substances, e.g. shop primers, paints, oils, waxes and inter?weld materials such as adhesives and sealants. It is aimed primarily at test laboratories performing such procedures. The data generated can be used by coating manufacturers to provide information for inclusion in safety data sheets and by occupational hygienists to identify thermal degradation products of significance in the performance of risk assessments and/or workplace exposure measurements. The data cannot be used to estimate workplace exposure directly.
ISO 15011-5:2011 is applicable to all coatings composed partly or wholly of organic materials that can be heated, during welding and cutting, preheating and straightening to temperatures at which thermal degradation products are generated and where it is not apparent what those degradation products are.
