(Practice)Standard Practice for Use of Qualitative Chemical Spot Test Kits for Detection of Lead in Dry Paint Films
Standard Practice for Use of Qualitative Chemical Spot Test Kits for Detection of Lead in Dry Paint Films
SCOPE
1.1 This practice covers the use of commercial spot test kits based on either sulfide or rhodizonate for the qualitative determination of the presence of lead in dry paint films.
1.2 This practice may also be used as a qualitative procedure for other dry coating films such as varnishes.
1.3 This practice provides a list of the advantages and limitations of chemical spot test kits based on sulfide and rhodizonate to allow the user to choose the appropriate spot test for a given circumstance.
1.4 This practice contains notes which are explanatory and not part of mandatory requirements.
1.5 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.
