ASTM E1521-14

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: E1521 − 01 (Reapproved 2006) E1521 − 14
Standard Test Method for

Liquid Holding Capacity of Granular Carriers
This standard is issued under the fixed designation E1521; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method is used to determine the liquid holding capacity (LHC) of granular carriers.
1.2 The values stated in either SI or inch-pound units are to be regarded as standard. The values given in parentheses are for
information only.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. For specific precautionary statements, see Section 5.
2. Summary of Test Method
2.1 Incremental amounts of suitable fluids are added to a known weight of granular carrier. The point at which the granules stick
to the sides of the container allows calculation of the LHC.
3. Significance and Use
3.1 This test method has been designed principally for granular carriers with LHC greater than 5.0 %. The incremental amount
of suitable fluid added can be adjusted down as needed for carriers with LHC less than 5.0 %.
3.2 This test method has been designed principally for granular carriers with a relatively rapid absorption of liquid. Some
materials may absorb liquids more slowly than the described times in the method. If such is the case, the time limit of two (2) min.
may be extended.
3.3 This test method is applicable to granules in the range from 4 to 100 mesh (4.75 to 0.150 mm).
4. Apparatus and Reagents
4.1 Buret Stand.
4.2 Buret, 10 to 25 mL, accurate to 0.2 mL.
4.3 Glass Bottle, 1 oz (29.6 mL), 29.6 mL, with poly seal cap (7 by 3.5-cm outside diameter).
4.4 Glass Bottle, 8 oz (236.8 mL), 236.8 mL, wide mouth with poly seal cap.
4.5 Suitable Fluids, dearomatized mixed aliphatic solvents like Exxsol(R) D110 from Exxon Mobile Chemical Company, that
boil in the range of 250–275°C and have a specific gravity of 0.80–0.82.
4.6 Balance, accurate to 60.1 g.
5. Safety Precautions
5.1 Before testing, read the precautionary statements on the product label and material safety data sheet. Take proper precautions
to prevent skin contact and inhalation of the fines and vapors. Take care to prevent contamination of the surrounding area. Always
wear the appropriate safety equipment and, where indicated, wear respiratory devices approved by NIOSH for the product being
tested.
6. Procedure
6.1 Weigh 7.0 6 0.1 g of granular carrier for LHC determination into a 29.6-mL glass bottle.
