The ASTM E1645-21 Standard Practice for Preparing Dry Paints Samples by Hot Plate or Microwave Digestion for Subsequent Lead Analysis standard provides procedures for treating dry paints samples using Hot Plate or microwave digestion techniques for lead content analysis. This method is suitable for digestion treatment of paints samples to ensure effective extraction of lead for subsequent quantitative analysis. The standard details the operating conditions, equipment requirements, sample preparation, and digestion steps of Hot Plate and microwave digestion, providing reliable technical support for accurate determination of lead content. The standard is widely used in paints quality control, environment monitoring and regulatory compliance testing to help ensure paints products meet safety standards, particularly in children's coatings and lead content control in building materials.
