    Significance and Use

    5.1 This practice can be used to evaluate unused oxygen removal ion exchange cartridges for conformance to specifications.

    5.2 This practice provides for the calculation of capacity in terms of the volume of water treated to an end point level of dissolved oxygen.

    5.3 The practice as written assumes that the oxygen removal ion exchange resins in the cartridge are either partially or fully regenerated. Regeneration of the resins is not part of this practice.

    5.4 This practice provides for the calculation of capacity on a cartridge basis.

    5.5 This practice may be used to test different size oxygen removal resin cartridges. The flow rate of test water and the frequency of sampling are varied to compensate for the approximate volume of resin in the test cartridge.

    1. Scope

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

    1.4 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.
