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 Procedure—Dry or Free-Flowing Material (Section 8), and Sampling Procedure—Moist 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.
1.1 These practices cover procedures for obtaining representative samples of ion-exchange materials. The following practices are included:
|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
