1.1本试验方法 2. 涵盖液化石油气中硫化氢的检测。测试的灵敏度约为4 mg/m 3. （每100英尺0.15至0.2粒硫化氢 3. )气体。 1.2以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1液化石油气及其燃烧产物不得对其接触的材料具有过度腐蚀性。H的潜在人员暴露危害 2. S也使硫化氢的检测和测量变得重要，即使在低浓度下也是如此。此外，在某些情况下，气体的气味不得令人反感。（见规范 D1835 和GPA 2140 .)

1.1 This test method 2 covers the detection of hydrogen sulfide in liquefied petroleum (LP) gases. The sensitivity of the test is about 4 mg/m 3 (0.15 to 0.2 grain of hydrogen sulfide per 100 ft 3 ) of gas. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 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. ====== Significance And Use ====== 4.1 Liquefied petroleum gases and their products of combustion must not be unduly corrosive to the materials with which they come in contact. The potential personnel exposure hazards of H 2 S also make the detection and measurement of hydrogen sulfide important, even in low concentrations. In addition, in some cases the odor of the gases must not be objectionable. (See Specification D1835 and GPA 2140 .)
