Lower Explosive Limit, the lowest concentration of a flammable liquid vapour and air mixture, expressed as a percentage by volume in air, in which an explosion will occur on ignition in a confined area
Lower Explosive Limit. In relation to a flammable contaminant means the concentration of the contaminant in air below which the propagation of a flame does not occur on contact with an ignition source.
Lower Explosive Limit M - R
lower explosive (flammable) level in air
Lower Explosive Limit. Lower Explosive Limit; the minimum concentration below which combustion will not occur.
Lower explosive limit. The lower limit of flammability of a gas or vapor at ordinary ambient temperatures expressed in percent of the gas or vapor in air by volume. This limit is assumed constant for temperatures up to 120oC (250oF). Above this, it should be decreased by a factor of 0.7 because explosibility increases with higher temperatures.
Lower Explosive Limit - The lower limit of flammability of a gas or vapor at ordinary ambient temperatures expressed in percent of the gas or vapor air by volume. This limit is assumed constant for temperatures up to 250° F(120° C) and is normally listed on a product's material safety data sheet.
Lower Explosive Limit. Minimum concentration of a combustible gas measured as a percentage of the total constituents present in the atmosphere that will combust when ignited.
lower explosive limit. The concentration of a gas below which the concentration of vapors is insufficient to support an explosion. LELs for most organics are generally 1 to 5 percent by volume. magnehelic gauge: a sensitive differential pressure or vacuum gauge manufactured by Dwyer Instrument Co. that uses a precision diaphragm to measure pressure differences. This gauge is manufactured in specific pressure or vacuum ranges such as 0 to 2 inches of water column. Magnehelic gauges are typically used to measure SVE system vacuums.
LOWER EARNINGS LIMIT. The minimum amount, approximately equivalent to the single personâ€(tm)s basic pension, which must be earned in any pay period before NI contributions are payable. Up to 5 April 1999, the lower earnings limit on which employer and employee NI contributions were based. From 6 April 1999 to 5 April 2000, the lower earnings limit on which employee NI contributions are based. From 6 April 2000, the lower earnings limit on which an employeeâ€(tm)s state benefits are calculated.
Lower explosive limit. The lower point for a range of concentrations of organic particles suspended in air that can be ignited by a sufficient energy source. Also called minimum explosive concentration (MEC).
Lowest effect level, same as LOEL
The lowest concentration of gas or vapor (% by volume in air) which will burn or explode if an ignition source is present.
Lower explosive limit. The minimum concentration of a combustible gas in air which will ignite if a source of ignition is present. Used interchangeably with the term "lower flammability limit" (LFL).
lower explosive limit metre
Lower Explosive Limit. The Lower Explosive Limit of a flammable gas or vapor (% by volume in air) in which explosion can occur upon ignition in a confined area.
See LOWER EXPLOSIVE LIMIT.
Lower Explosive Limit. The lower limit of flammability of a gas or vapor. It is usually expressed in percentage of gas or vapor in air by volume.
lower flammable or explosive limit meter(s)
Lower Explosive Limit. The concentration of flammable gas or vapour in air above which an explosive gas atmosphere will be formed
Lower earnings limit. This is the least amount someone must earn before they have to pay national insurance .
lower explosive limit. the concentration of flammable vapors in the air is below a level which will result in a flame, given an ignition source.
LOWER EXPLOSIVE LIMIT. See "LEL."
The lowest concentration of the material in air that can be detonated by spark, shock or fire, etc.
LOWER EXPLOSIVE LIMITS. The lowest concentration of gas or vapor (% by volume in air) that burns or explodes if an ignition source is present at ambient temperatures. The lowest concentration of fuel vapor mix to support combustion. When the level is below the lower explosive limit, it is termed too lean to burn. See Flammable Limits.
Lower Explosive Limit. The concentration of a compound in air below which the mixture will not catch on fire.
