ASTM D4004 Standard Test Methods for Rubber—Determination of Metal Content by Flame Atomic Absorption (AAS) Analysis
ASTM D4004橡胶的标准试验方法.用火焰原子吸收(AAS)分析法测定金属含量
These test methods are suitable for process control, for product acceptance, and for research and development.

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 and health practices and determine the applicability of regulatory limitations prior to use.
