"Standard Test Method for Determining the Initial Efficiency of Materials to Penetration by Particulates Using Latex Spheres"


This test method establishes procedures for measuring the initial particle filtration efficiency of materials using monodispersed aerosols.

Standard Type(s)
Test Method

A definitive procedure that produces a test result: Examples of test methods include, but are not limited to: identification, measurement, and evaluation of one or more qualities, characteristics, or properties. A precision and bias statement shall be reported at the end of a test method.

Personal Protective Equipment
Eye and Face Protection

All equipment and/or accessories (whether or not detachable) designed and manufactured specifically to protect the eyes and/or the entire face (not including the top of the head). Exposure to the eye or face hazards from flying particles, molten metal, liquid chemicals, acids, or caustic liquids, chemical gasses, or vapors, potentially infected material or potentially harmful light radiation.

  • Face masks
Body Protection

All items of clothing and/or accessories (whether or not detachable) designed and manufactured to provide specific protection. This includes bullet-proof clothing, general protective clothing and full body ensembles that protect from cuts, radiation, temperature extremes, hot splashes from molten metals and other hot liquids, potential impacts from tools, machinery and materials and hazardous chemicals. Examples of body protection include laboratory coats, coveralls, vests, jackets, aprons, surgical gowns and full body suits
