ASTM C871-2011 Standard Test Methods for Chemical Analysis of Thermal Insulation Materials for Leachable Chloride,Fluoride,Silicate,and Sodium Ions
ASTM C871-2011 可濾去氯化物、氟化物、硅酸鹽及鈉離子的絕熱材料化學分析的試驗方法。

ASTM C871-2011標準適用范圍：

1.1 These test methods cover laboratory procedures for the determination of water-leachable chloride, fluoride, silicate, and sodium ions in thermal insulation materials in the parts per million range.

1.2 Selection of one of the test methods listed for each of the ionic determinations required shall be made on the basis of laboratory capability and availability of the required equipment and appropriateness to the concentration of the ion in the extraction solution.

1.3 The values stated in inch-pound units to be regarded as standard. the values gives in parentheses are mathematical conversions to SI units that provided for information only and are not considered 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.
