3.2 除超纯氢外，由供需双方商定氩含量是否列人纯度计算。
In addition to the ultrapure hydrogen, whether argon concentration will be listed in purity calculation can be defined by both supplier and buyer.
4  规则Rule
4.1 连续、稳定生产的瓶装（或集装格装）纯氢、瓶装高纯氢以生产厂一个操作班生产的或一次充灌的产品组批，用户以同一车载里或同批进货量组批。每批产品的瓶数（或格数）不应超过300.
Continuous and stable production of bottled (or container cased) pure hydrogen, bottled high purity hydrogen will be a batch produced by manufacturer’s one operation shift or once filling products, users will set the batched product with the same truck or same batch material. Every batch of bottles number should not exceed 300.
4.2 瓶装或集装格装纯氢和瓶装高纯氢产品按表2规定的批量随机抽样检验，成批验收。当有任何一项指标的检验结果不符合本部分技术要求时，应重新加倍随机抽样检验，如果仍有任
何一项指标不符
合本部分技术要求时，则判该批产品不合格。
4.2 Bottled or container cased pure hydrogen and bottled high purity hydrogen product will be random sampling inspection as stipulated in the table 2, acceptance by batch. If any test result does not conform to the technical specification, it should be double random sampling inspection; any indication that it still has the discrepancy with the technical requirements, this batch of product is deemed as unqualified.
