Standard Operating Procedure for the Preparation of Lead-Containing Paint Films and Lead-in-Paint Diagnostic Test Materials

摘要

This Standing Operating Procedure (SOP) describes the preparation of stand-alone, leaded paint films prepared according to old paint recipes. Further, this SOP describes the use of these paint films for the preparation of simulated old paints on a variety of substrates. Substrates used included wood, steel, masonry, and plaster. The leaded paint varied in pigment, color, and the presence of ions that have a potential for interfering with the lead measurement performed with different methods, including various types of test kits.
