Significance and Use
Use of this practice in conjunction with realistic maximum volatility tolerance level can help minimize the risk of oxygen sensor dysfunction from formed-in-place-sealants in transportation applications. This practice provides a method for determination of percentage volatiles in silicone elastomers. The volatile silicones from a commercial silicone are primarily cyclo dimethyl-siloxane. Other species present having GC retention times similar to those of the cyclics are assumed to be silicone as well.
Scope
1.1 This practice covers a means to determine the percent silicone-producing volatiles present in heat-cured silicone rubber and room temperature-cured silicones (RTV).
1.2 Silicone-producing volatiles contribute to fouling of oxygen sensor systems used in the control of vehicle emissions.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
