1 Scope 1.1 Applicable equipment This Standard applies to newly produced, outdoor cooking specialty gas appliances, hereinafter referred to as “appliances”, constructed entirely of new, unused parts and materials. Note: Appliances submitted for examination under this Standard are classified as portable or stationary. These products are not intended for commercial use. 1.2 Applicable equipment for recreational vehicle This Standard applies to recreational vehicle gas outdoor cooking appliances. 1.3 Non-applicable equipment This Standard does not apply to a) appliances for installation in or on a boat; b) appliances for installation in the interior living space of a recreational vehicle; and c) fryers/smokers for installation on a recreational vehicle. 1.4 Outdoor cooking specialty gas appliance An appliance can be a a) fryer; b) boiler; c) smoker; d) tabletop gas grill incorporating an open top broiler, top burner(s), griddle, or any combination; e) combination of any of the above; or f) recreational vehicle outdoor cooking specialty gas appliance. Note: A tabletop gas grill is not a built-in type. 1.5 Fuel systems Appliances can be for connection to a) a fixed fuel piping system, including a recreational vehicle’s low-pressure liquefied petroleum (LP) gas system; or b) a self-contained LP gas or propane gas supply system of a single cylinder with a maximum size of 20 lb (9.1 kg) of fuel. 1.6 Fuel types This Standard applies to appliances operating at inlet gas pressures not to exceed 1/2 psi (3.5 kPa) for connection to a fixed fuel piping system for use with a) natural gas; b) LP gases; and c) LP gas-air mixtures.

This document is applicable to the measurement of the total silicon content in gaseous matrices such as biomethane and biogas. Silicon is present in a gas phase contained predominantly in siloxane compounds, trimethylsilane and trimethylsilanol. The analytical form of the silicon measured in liquid phase after conducted sampling and derivatization procedure is soluble hexafluorosilicate anion stable in slightly acidified media. Total silicon is expressed as a mass of silicon in the volume of the analysed gas. This document is applicable to stated gaseous matrices with silicon concentrations up to 5 mg/m3, and it is prevalently intended for the biomethane matrices with Si mass concentration of 0,1 mg/m3 to 0,5 mg/m3. With adaptation to ensure appropriate absorption efficiency, it can be used for higher concentrations. The detection limit of the method is estimated as 0,05 mg/m3 based on a gas sample volume of 0,020 m3. All compounds present in the gas phase are volatile at the absorption and derivatization temperature and gaseous organosilicon species are trapped in absorbance media and derivatized into analytical silicon that is measured by this method. The concentration of the silicon is measured in diluted derivatization media using atomic emission spectrometry upon atomisation/ionisation in microwave or inductively coupled plasma. Unless specified otherwise, all volumes and concentrations refer to standard reference conditions (temperature, 273 K, and pressure, 101,325 kPa). NOTE When using appropriate dilution factors, the method can also be applied for silicon concentrations above 5 mg/m3.

1.1 This specification covers Liquefied Natural Gas (LNG) density calculation models for use in the calculation or prediction of the densities of saturated LNG mixtures from 90K to 120K to within 0.1 % of true values given the pressure, temperature, and composition of the mixture. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
