At the moment, the phenomena orange peel, is either evaluated visually or by profilometry, whieh can only be used in laboratory applieations. Physieal paint standards with different degrees of orange peel or other visual instruments are used as support tools for the visual evaluation (Tension Meter, Landoldt Rings). Therefore, we believed that it is nec-... 

A solvent, as defined by paint standards, is a volatile liquid that is incorporated primarily for vehicle solvency and control of the application characteristics. The solvent content is the calculated weight of solvents in a specific volume of paint. This definition is not equivalent to the definition of VOC compound because it does include compounds which are excluded by EPA (see more on this subject in Section 18.1). 

The American Society for Testing Materials (ASTM) has provided validated procedures for quantification of lead in various types of paint samples. ASTM E 1645 prescribes preparation of paint lead chips for analysis while methods ASTM E 1613, ASTM E 1775, and ASTM PS 88 are directed to measurements of lead. The NIST has made paint standard reference materials (SRM) available for calibration and validation of lead paint measurement methodologies. SRM 2579 is available as a paint film while SRM 2589 consists of paint samples collected from interiors of various homes and prepared as a homogeneous powder, 100,000 ppm (10%) lead, with >99% of the particles being <100 pm in size. 

In February 1955, the American Standards Association (ASA) issued its directive Z66.1-1955, which set forth a 1% lead in paint standard (with...
