1.1 本规范涵盖了原始氧气瓶燃烧程序中使用的带有固定铂样品架的烧瓶和封盖 ( 1. , 2. ). 2. 注1: 本规范最初由美国化学学会分析化学部微化学仪器委员会制定 ( 3. ). 使用电力的设备类型规范 ( 2. , 4- 7. ) 或红外线 ( 8. ) 由于缺乏这些方面的经验，因此不包括点火。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the flask and closure, with a fixed platinum sample holder, used in the original oxygen-flask combustion procedures ( 1 , 2 ). 2 Note 1: This specification was originally developed by the Committee on Microchemical Apparatus, Division of Analytical Chemistry, American Chemical Society ( 3 ). Specifications for types of apparatus that utilize electric ( 2 , 4- 7 ) or infrared ( 8 ) ignition are not included because of lack of experience with these. 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 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.
