本标准规定了天然气中汞(包括元素汞、二甲基汞和二乙基汞)的A和B二种测定方法。方法A规定在大气压下取样,采用高锰酸钾溶液吸收汞,接着汞离子被还原,然后用冷原子荧光测 汞仪分析。取样2h,检出下限是0.3μg/m。芳烃会产生干扰。假若存在芳烃,建议使用B法。方法B规定在大气压或更高压力下取样,采用金丝吸附汞,接着脱附,然后用冷原子荧光测汞仪分 析。在大气压下取样2h,检出下限是0.03μg/m。方法A用于高含汞天然气(>0.5μg/m)的测定,方法B用于汞浓度较低的天然气(10~1μg/m)的测定。

This European Standard specifies the method of test for determining the gas energy consumption in gas-fired domestic ovens when they are being used in one or more of the oven cooking modes defined in 3.1. It applies to the gas-fired domestic ovens which are capable of utilizing gases of group H or group E, possibly after conversion according to instructions for use. This European Standard applies to these gas-fired domestic ovens, whether they are separate appliances or component parts of domestic cooking appliances. This European Standard also applies to domestic appliances that can utilize gas and/or electrical energy to provide heat for cooking when the ovens are utilizing gas energy to provide heat for cooking, but not when electric energy is used to provide any or all of the heat for cooking in the oven. It is not applicable to:- microwave combination ovens; - small cavities ovens (3.2); - oven cavities not provided with devices to detect and control the temperature for the preparation of food; - cooking modes others than defined in 3. and 3.; - ovens connected to a chimney in which the gas energy for cooking provides, by design, also space and/or water heating; - appliances designed for use with gases of the third family only. This European Standard is concerned neither with safety nor with overall performance requirements.

This European Standard specifies two test methods (method T and method B) to determine the explosion limits of gases, vapours and their mixtures, mixed with air or an air / inert gas mixture (volume fraction of the oxygen < 21 %) and the limiting oxygen concentration. This European Standard applies to gases, vapours and their mixtures at atmospheric pressure for temperatures up to 200 °C.

5.1x00a0;Crude oils and oil sands bitumen contain naturally occurring acidic species. Acidity of crude oil has been implicated in corrosion of distribution and process systems. The relative amount of these materials can be determined by titrating with bases. The acid number is a measure of this amount of acidic substance in the oil under the conditions of the test. 5.2x00a0;Acid number of crude and distilled petroleum fractions has been measured by Test Method D664. Test Method D664 was developed for the analysis of lubricants and biodiesel. The titration solvent used in Test Method D664 does not properly address dissolving difficult samples such as crude oil, bitumen, and high wax samples addressed in this test method. Refer to Appendix X1. 5.3x00a0;Test Method D974 is also not applicable to measuring acidity of crudes and highly colored samples because the indicator is not visible or it is difficult to discern a color change to detect the end point of the titration. 1.1x00a0;This test method covers the determination of acidic components in crude oil and petroleum products including waxes, bitumen, base stocks, and asphalts that are soluble in mixtures of xylenes and propan-2-ol. It is applicable for the determination of acids whose dissociation constants in water are larger than 10x2013;9; extremely weak acids whose dissociation constants are smaller than 10x2013;9 do not interfere. The values obtained by this test method may not be numerically equivalent to other acid value measurements. The range of KOH acid numbers included in the precision statement is 0.18201;mg/g to 168201;mg/g. 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3x00a0;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 and health practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 7 on Safety Precautions. 1.4x00a0;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.
