ANSI Z83.11/CGA 1.8 standard. Note: when you look at all the marks used in the Garland group, you will notice that GCR uses only CSA and GCI uses predominantly UL. The reason for this comes down to two reasons.
Properties And Characteristics Of Fuel Gases Expansion Factors The petroleum gases most commonly used in the gas industry are natural gas and it two processed derivatives, When the temperature of a liquid increases, it causes the propane and butane. The two most commonly used fuels in liquid to expand, causing the volume of the liquid to increase commercial cooking equipment are natural gas and propane.
