ASTM D1820-95

Standard Test Method for Hydrolyzable Chlorine Compounds in Chlorinated Aromatic Hydrocarbons (Askarels) (Withdrawn 2000)

SCOPE
1.1 This test method covers the determination of hydrolyzable chlorine compounds in chlorinated aromatic hydrocarbons (askarels).  
1.2 The values stated in metric units are to be regarded as the standard.  
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.
