6、························⋯⋯16GB18985-2003前言本标准的全部技术内容为强制性。本标准代替GBn268-1987。技术内容和编写结构均有所改变。与原有标准有如下差异:本标准增加了规范性引用文件及术语和定义，保留了原标准中的四种潜水装具的供气量和用轻、中、重三种劳动强度对供气流量进行划分的方法。修订中规定了使用不同潜水装具和采用不同潜水方法进行潜水作业的最大安全深度，规定了氮氧饱和时和氦氧饱和时饱和居住舱的加压方法，规定了氦氧饱和巡回潜水时潜水钟的加压方法，规定了氦氧饱和

7、潜水备用的治疗用氦氧混合气的数量。修订中对原标准使用字母、换算系数和计算公式进行了一些删改，删除了一些实际使用价值不大的计算公式。本标准的附录A,附录B、附录C为资料性附录。本标准由中华人民共和国交通部提出。本标准由交通部救捞与水下工程标准化技术委员会归口。本标准起草单位:上海海洋水下工程科学研究院。本标准主要起草人:荆岩林、张耀然、张国光、陆莲芳、高桂珍、帅开林、陈迈若。本标准所代替标准的历次版本发布情况为:GBn268-19870GB18985-2003潜水员供气量1范围本标准规定了满足潜水员水下作

8、业所需的最低呼吸用气体流量和完成潜水作业所需的最低呼吸用气体量。本标准适用于潜水员使用通风式、水面供气需供式、自携式或引射再生式氦氧潜水装具，呼吸压缩空气或人工配制的混合气(氮氧、氮氧或氦氮氧)进行常规或饱和潜水作业。潜水装具、供气设备等设计、制造可参考使用。2规范性引用文件下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注日期的引用文件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的
