    Significance and Use

    5.1 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 Procedure—Dry or Free-Flowing Material (Section 8), and Sampling Procedure—Moist Material (Section 9).

    5.2 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 practices2 cover procedures for obtaining representative samples of ion-exchange materials. The following practices are included:

     

    Sections

    Practice A—Sampling from a Single Package and
     Multiple Package Lots or Shipments


    4 to 11

    Practice B—Sampling from Fixed Bed Ion-Exchange
     Equipment Having Unrestricted Head Room


    12 to 16

    Practice C—Sampling from Fixed Bed Ion-Exchange
     Equipment Having Restricted Head Room


    17 to 21

    1.2 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.
