4.General
一般要求
4.1 A surface will be considered to be oxygen clean if it has undergone a cleaning process that ca
n be demonstrated to produce repeatable results that will satisfy the acceptance criteria in this specification.
如果表面清洗所用的清洗工艺的复检结果能够满足本文件中规定的验收标准，那么，这样的表面将被视为符合氧气级清洗要求。
4.2 When individual equipment item inspections for oxygen cleaning are not feasible or practical (e.g., for mass produced or commodity items such as cylinders, valves, or gaskets), Air Products might require that the cleaning process successfully pass an audit to the acceptance criteria in this specification. Audits shall be conducted before first use and then periodically and whenever a cleaning process is changed.
当对某单件设备进行氧气清洗检查不可行或不切实际时（例如钢瓶、阀门或垫片之类的大批量生产的物件或商品），APCI可能要求清洗工艺必须成功地通过本文件验收标准的审计。首次使用之前必须进行审计，然后定期审计，工艺改变时必须审计。
4.3 Parts of assemblies shall be cleaned separately before assembling or fabricating renders any surface inaccessible for cleaning or inspection. Pipe and fittings shall be cleaned before starting fabrication.
在组装或制造任何不能以直接方式清洗或检查的表面之前，必须分别清洗组件的各部件。在开始制造之前，管道和配件必须清洗。
4.4 The handling, storage, and use of all chemicals shall be according to guidelines contained in their Material Safety Data Sheets (MSDS). Used chemicals shall be disposed of in a lawful manner.
所有化学品的搬运、储存和使用都必须执行各自的物料安全数据表（MSDS）规定的指导原则。用后的化学品必须用合法的方式加以处理。
4.5 For additional information on cleaning methods, see CGA G-4.1, EIGA 33/97, and ASTM G 93.
