25、 2017 All rights reserved ISO/TS 21522:2017(E) Introduction Rubber process fumes are emitted during the rubber manufacturing process. These rubber fumes have been the topic of many studies, for example ISO/TR 21275. ISO/TR 21275 gives a bibliographic study of 95 publications describing the compositi

26、ons of fumes that could be emitted during the processing of rubber. The study also confirms that rubber fumes are a complex and variable mix of chemicals which have a wide range of possible sources and origins, including chemicals generated from the chemical reactions occurring in the rubber compoun

27、ds during processing and curing. Some of these chemical substances can be hazardous. ISO/TR 21275 demonstrates the need for standardization of test methods to identify and quantify the hazardous chemicals to which the operators of the factories producing rubber articles may be exposed, allowing the

28、identification and mitigation of potential health risks. ISO/TS 17796 specifies a qualitative method (by thermodesorption gas chromatography mass spectrometry) for the identification of volatile components in rubber fumes, and is applicable to the screening of emissions from the processing of rubber

29、 compounds in the ambient workplace and storage environment. The document is an efficient tool for identifying hazardous substances contained in rubber process fumes. If a hazardous component is identified in rubber fumes, then the most efficient way to eliminate risk for the operators is to substit

30、ute the substance or the process which generates the hazardous component. In cases where there is no substitute, then the risk can be reduced by controlling the exposure of the operators to the hazardous component. Test methods are therefore necessary to quantify each hazardous substance. Table 1 pr

The list of components is by no means exhaustive but helps to highlight the diverse areas and products in which rubber is used. Table 1 Range of rubber components Types
