Description:
The report describes results of an interlaboratory study to estimate repeatability (precision of analyses performed by a single laboratory) and reproducibility (precision analyses performed by different laboratories) of a consumer products volatile organic compound (VOC) measurement method based on EPA Method 24 (for VOCs in surface coatings). (NOTE: Consumer products are significant sources of VOCs, which are precursors to the formation of ozone in photochemical smog.) The mean method repeatability was found to be 2.7 weight percent VOC, and the mean method reproducibility was found to be 4.8 weight percent VOC. Method repeatability ranged from 0.2 to 4.4 weight percent VOC, and the reproducibility ranged from 0.6 to 11.9 weight percent VOC. The precision of the consumer products VOC method for consumer product samples is similar to that of EPA Method 24 applied to surface coatings. Results show that the consumer products VOC method is suitable for analyzing the volatile content of a wide variety of consumer products.
