ASTM D7367-19e1

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.

Hydraulic Planting
This standard is issued under the fixed designation D7367; 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 quantitative test method determines the water holding capacity of fiber mulches, including wood, paper, and
agriculturally derived and blended fiber mulches that are used for hydraulic seeding and planting. Results from this testing can be
used as a quality assurance and/or quality control data for manufacturing processes.
1.2 There are no known limitations to this test method.
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this
standard.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice
D6026.
1.4.1 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as the industry
standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not
consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives;
and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering data.
1.5 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.
1.6 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.

4. Summary of Test Method
4.1 A representative sample of a fiber mulch is taken from a packaged bale or bag. The representative sample is thoroughly
mixed to obtain 3 test specimens. The test specimens are allowed to condition for 24 h. Then, the mass of each test specimen is
determined as is the mass of a sieve and a sieve pan. Test water is then added to the test specimen and mixed. The test water and
fiber is then poured over a sieve and evenly distributed. The sieve is then placed in bowl to allow the fiber mulch to saturate. After
saturation, the sieve is
