This standard is being balloted for withdrawal with no replacement because the D34.01.05 task group has concluded that this standard is neither a complete screening method nor a complete laboratory method does not match the scope of the D34.01.05 task group on Screening Methods. This method is, for all intents and purposes, a combination of the USEPA SW-846 Method 9041a (using pH paper) and Method 9045d (using pH meters). Since existing and readily available methods, although not ASTM methods, more than adequately cover the topic, the D34.01 subcommittee is balloting this standard for withdrawal so as not to duplicate efforts or infringe on intellectual property of others.
