ASTM E1291-99(2003) PDF

1.1 This test method estimates the relative hazard of handling a liquid chemical, pesticide, or mixture, where exposure to vapors from spilled liquids may result.

1.2 The results of this test method may also be used to evaluate and compare the relative hazard between two liquid chemicals.

1.3 This test method measures hazard rather than quantitative toxicity because the amount inhaled is governed by vapor pressure. It is recognized that the vapor air mixture in this test is not completely saturated, although for brevity it is known as saturated vapor.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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. See Section for additional hazard information.
