ASTM D5955 Standard Test Methods for Estimating Contribution of Environmental Tobacco Smoke to Respirable Suspended Particles Based on UVPM and FPM
ASTM D5955根据UVPM和FPM评定环境香烟烟雾对可吸入悬浮粒子影响的试验方法
1. Scope
1.1 These test methods pertain to the sampling/analysis of respirable suspended particles (RSP) and the estimation of the RSP fraction attributable to environmental tobacco smoke (ETS). These test methods are based on collection of total RSP on a membrane filter, extracting the collected material in methanol, and measuring total ultraviolet absorbance or fluorescence, or both, of this extract. The corresponding methods of estimation are termed ultraviolet particulate matter (UVPM) and fluorescent particulate matter (FPM), respectively.
1.2 These test methods are compatible with, but do not require the determination of solanesol, which is also used to estimate the contribution of ETS to RSP (see Test Method D 6271).
1.3 The sampling components consist of a preweighed, 1.0-m pore size polytetrafluoroethylene (PTFE) membrane filter in a filter cassette connected on the inlet end to a particle size separating device and, on the outlet end, to a sampling pump. These test methods are applicable to personal and area sampling.
1.4 These test methods are limited in sample duration only by the capacity of the membrane filter (about 2000 g). These test methods have been evaluated up to a 24-h sample duration with a minimum sample duration of at least 1 h.
1.5 Limits of detection (LOD) and quantitation (LOQ) for the UVPM test method at a sampling rate of 2 L/min are, respectively, 2.5 g/m3 and 8.3 g/m3 for a 1-h sample duration and 0.3 g/m3 and 1.0 g/m3 for an 8-h sample duration. The LOD and LOQ for the FPM test method at a sampling rate of 2 L/min are, respectively, 1.4 g/m3 and 4.7 g/m3 for a 1-h sample duration and 0.2 g/m3 and 0.6 g/m 3 for an 8-h sample duration.
1.6 The values stated in SI units are to be regarded as standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary information is given in 13.6.
