ASTM F2588-12(R2020) pdf free download.Standard Test Method for Man-In-Simulant Test (MIST) for Protective Ensembles
1. Scope
1.1 This test method specifies the test equipment and procedures for conducting tests to estimate the entry of chemical agent vapor simulant through protective ensembles while worn by test subjects. 1.2 This test method permits the evaluation of protective ensembles consisting of protective garments or suits, gloves, footwear, respirators, and interface devices. 1.3 The results of this test method yield local physiological protective dosage factors at individual locations of the human body as well as a systemic physiological protective dosage factor for the entire ensemble. 1.4 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions: 3.1.1 chemical agent vaporsimulant, n—a substance used to replicate vapor characteristics of a chemical agent which is a more toxic substance. Discussion—In this test method, methyl salicylate is used as a chemical agent vapor simulant for the blister agent, distilled mustard. 3.1.2 chemical terrorism agent, n—a liquid, solid, gaseous, or vapor chemical warfare agent or a toxic industrial chemical used to inflict lethal or incapacitating casualties, generally on a civilian population as a result of a terrorist attack. 3.1.3 interface area, n—a location on the body where two or more protective clothing items (for example, suits, garments, hoods, gloves, footwear, respirators, or other items) come into contact. Discussion—Interfaces are potential breaches that could allow entry of chemicals into the interior of the protec- tive ensemble.3.1.4 interface device, n—an item of the ensemble that is intended to provide protection to the interface area. 3.1.5 local physiological protective dosage factor (PPDF I ), n—a physiological protective dosage factor at a specific location on the body. Discussion—In this test method, local physiological protective dosage factors are measured at 30 different locations on the body. 3.1.6 onset of symptoms exposure dosage (OSED), n—the dosage that causes threshold effects to the average human. 3.1.7 passive adsorbent dosimeters (PADs), n—two-sided packets with one side made from a permeable film and the second side made from a chemically impermeable film, which are filled with absorbent material, and are placed on the skin at specific locations of the body to collect any chemical vapor challenge that has infiltrated the protective ensemble. 3.1.8 physiological protective dosage factor(PPDF), n—the factor by which protection is improved against effects from vapor exposure for the protected individual compared with whole-body exposure of the unprotected individual. 3.1.9 protective ensemble, n—the combination of protective clothing with respiratory protective equipment, hoods, helmets, gloves, boots, communication systems, cooling devices, and other accessories intended to protect the wearer from a potential hazard when worn together. Discussion—For evaluating the vapor penetration and permeation resistance of protective ensembles against chemical agent vapor simulant, the protective ensemble in- cludes all those clothing items or accessories, which are necessary to provide resistance to inward leakage by chemical vapors.
4. Summary of Test Method
4.1 This test method establishes procedures for testing complete protective ensembles worn by test subjects when exposed to chemical agent vapor simulant. Methyl salicylate (MeS) is used to simulate chemical agent vapor penetration through ensemble interfaces and openings. 4.2 This test method tests the vapor penetration and perme- ation resistance of a protective ensemble by the placement of passive adsorbent dosimeters (PADs) containing sorbent ma- terial onto the test subjects at specific locations on the body. 4.3 After test subjects wearing the ensemble to be evaluated finish a series of activities inside the test chamber, these PADs are removed from the test subject and analyzed for MeS.
