1.1 本指南适用于为冶金加工场所选择适当的ASTM标准分析方法，以符合《含氰溶液分析国际氰化物管理规范指南》。 1.2 本指南中的分析方法推荐用于通过试验方法对总氰化物、有效氰化物、弱酸可分离氰化物和游离氰化物进行采样保存和分析 D2036 , D4282 , D4374 , D6888 , D6994 , D7237 , D7284 和 D7511 . 1.3 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。 1.4 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。 1.5 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 本指南旨在选择适当的氰化物测量方法，以符合与含氰化物溶液分析相关的国际氰化物管理规范指南。在工艺溶液和排放物中分析氰化物，以应用规范指南；然而，不适当的样品收集和保存可能会导致显著的正偏差或负偏差，可能导致过度报告或少报告氰化物释放到环境中。 5.2 本指南包含拟用于氰化物常规监测的比较试验方法。假设所有使用本指南所列方法的人都是经过培训的分析员，能够熟练、安全地执行这些方法。预计工作将在配备适当的实验室中进行，采用适当的质量控制实践，如指南中所述 D3856 .

1.1 This guide is applicable for the selection of appropriate ASTM standard analytical methods for metallurgical processing sites to conform to International Cyanide Management Code guidance for the analysis of cyanide bearing solutions. 1.2 The analytical methods in this guide are recommended for the sampling preservation and analysis of total cyanide, available cyanide, weak acid dissociable cyanide, and free cyanide by Test Methods D2036 , D4282 , D4374 , D6888 , D6994 , D7237 , D7284 , and D7511 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 This guide is intended as a means for selecting the proper methods for measuring cyanide to conform to the International Cyanide Management Code guidance related to the analysis of cyanide bearing solutions. Cyanide is analyzed in process solutions and in discharges in order to apply code guidance; however, improper sample collection and preservation can result in significant positive or negative bias, potentially resulting in over reporting or under reporting cyanide releases into the environment. 5.2 This guide contains comparative test methods that are intended for use in routine monitoring of cyanide. It is assumed that all who use methods listed in this guide will be trained analysts capable of performing them skillfully and safely. It is expected that work will be performed in a properly equipped laboratory applying appropriate quality control practices such as those described in Guide D3856 .
