    Significance and Use

    This practice will be used most frequently to sample materials as received from the manufacturer in the original shipping container and prior to any resin-conditioning procedure. Since certain ion-exchange materials are supplied by the manufacturer in the dry or free-flowing state whereas others are supplied moist, it is necessary to employ two different sampling devices. Therefore, this practice is divided into Sampling ProcedureDry or Free-Flowing Material (Section 8), and Sampling ProcedureMoist Material (Section 9).

    Once the sample is obtained, it is necessary to protect the ion-exchange materials from changes. Samples should be placed in sealable, gasproof containers immediately.

    1. Scope

    1.1 These practices cover procedures for obtaining representative samples of ion-exchange materials. The following practices are included:
