1.1 这些规程描述了使用传输标准校准环境、工作场所或室内臭氧监测器的方法。 1.2 这些实践描述了五种类型的传输标准: 练习A -分析仪器， 实践B -硼酸碘化钾（BAKI）手动分析程序， 实践C -含过量一氧化氮的气相滴定， 实践D -用过量臭氧进行气相滴定，以及 练习E -臭氧发生器装置。 1.3 这些实践描述了建立转让标准权威的程序:资格、认证和定期重新认证。 1.4 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。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 参见第节 8. 具体预防说明。 1.6 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。 ====意义和用途====== 5.1 O的反应性和不稳定性 3. 排除O的存储 3. 适用于任何实际时间长度的浓度标准，并排除了O的直接认证 3. 此外，没有任何可用的固体火箭发动机可以轻松直接适应O的生成 3. 类似于二氧化硫和氮氧化物渗透装置和标准气瓶的标准。动态生成O 3. 有紫外线辐射源时，浓度相对容易。然而，准确地证明O 3. 浓度作为主要标准要求通过全面规定的分析程序测定浓度，每次需要标准时都必须进行分析。 5.2 一次紫外标准光度计通常在受控条件下的固定位置使用，用于验证传输标准，然后将传输到使用环境臭氧监测器的现场。参见练习 D5110 . 5.3 该程序的优点是: 5.3.1 所有O 3. 给定网络或区域中的监控器可追溯到单个主要标准。 5.3.2 在受控条件下，一级标准仅在一个位置使用。 5.3.3 传输标准比主要标准更坚固，更易于携带。 5.3.4 传输标准可用于相互比较各种主要标准。

1.1 These practices describe means for calibrating ambient, workplace or indoor ozone monitors, using transfer standards. 1.2 These practices describe five types of transfer standards: Practice A —Analytical instruments, Practice B —Boric acid potassium iodide (BAKI) manual analytical procedure, Practice C —Gas phase titration with excess nitric oxide, Practice D —Gas phase titration with excess ozone, and Practice E —Ozone generator device. 1.3 These practices describe procedures to establish the authority of transfer standards: qualification, certification, and periodic recertification. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. See Section 8 for specific precautionary statements. 1.6 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. ====== Significance And Use ====== 5.1 The reactivity and instability of O 3 precludes the storage of O 3 concentration standards for any practical length of time, and precludes direct certification of O 3 concentrations as SRM's. Moreover, there is no available SRM that can be readily and directly adapted to the generation of O 3 standards analogous to permeation devices and standard gas cylinders for sulfur dioxide and nitrogen oxides. Dynamic generation of O 3 concentrations is relatively easy with a source of ultraviolet (UV) radiation. However, accurately certifying an O 3 concentration as a primary standard requires assay of the concentration by a comprehensively specified analytical procedure, which must be performed every time a standard is needed. 5.2 The primary UV standard photometers, which are usually used at a fixed location under controlled conditions, are used to certify transfer standards that are then transported to the field sites where the ambient ozone monitors are being used. See Practice D5110 . 5.3 The advantages of this procedure are: 5.3.1 All O 3 monitors in a given network or region may be traced to a single primary standard. 5.3.2 The primary standard is used at only one location, under controlled conditions. 5.3.3 Transfer standards are more rugged and more easily portable than primary standards. 5.3.4 Transfer standards may be used to intercompare various primary standards.
