The pressure exerted by an individual gas in a mixture of gases; partial pressure of a gas is the product of the dry gas fraction and the barometric pressure of the mixture. SYN: tension (PGAS).
Measures the filtration efficiency of a respirator against small dry particles of a specific size, usually 0.1 micron. The filtration efficiency is calculated by comparing the results of the test samples to the results of control counts without a respirator in place. (Reference ASTM F 2299) A face mask is considered to be sub-micron filtering if the PFE is greater than or equal to 98% as referenced in ASTM F 2100.
Common measurement for concentrations by volume of trace contaminant gases in the air (or chemicals in a liquid); 1 volume of contaminated gas per 1 million volumes of contaminated air or 1? in $10,000.00 both equal 1 ppm. Parts per million = ?g/mL or mg/L.
Antibodies formed in one person are transferred to another to provide temporary protection.
