1. Calibrate each personal sampling pump with a representative sampler in line. 2. Remove the caps of the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. NOTE: With a multi-bed sorbent tube, it is extremely important to sample in the correct direction, from least to maximum strength sorbent. 3.
Paint and Coatings Volatile Content Testing – ASTM D2369 & EPA Method 24. VOC testing, will often include utilizing ASTM D2369 test standards for finding volatile organic compound in coatings and paint. VOC testing describes a procedure for the determination of the weight percent volatile content of solvent-reducible and water-reducible coatings.
