1. Scope | ||||||||||||
1.1?These test methods cover the determination of lead, zinc, copper, and manganese in raw rubber and rubber compounds, vulcanized or unvulcanized. The level at which the metals are present is taken into account by suitable adjustments of sample mass and dilution. 1.2?Certain compounding ingredients, present in the rubber sample will dictate which of the methods should be used. Refer to Section 3. Five methods of determination are as follows:
1.3?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
