Phạm vi áp dụng / Scope of standard

1.1 This practice covers the determination of the performance of oxygen removal ion exchange resin cartridges in the regenerated form when used for removing dissolved oxygen from water. The test can be used to determine the initial capacity of unused cartridges or the remaining capacity of used cartridges. In this case, performance is defined as oxygen removal capacity (or throughput) to a defined endpoint.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
