ASTM D6567-18

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: D6567 − 17 D6567 − 18
Standard Test Method for
Measuring the Light Penetration of a Rolled Erosion Control
1
Product (RECP)
This standard is issued under the fixed designation D6567; 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 covers measuring the amount of incandescent light that penetrates through a rolled erosion control product.
1.2 This test method does not provide light penetration values for RECPs under variable normal sun and soil conditions. This
test method determines nominal light penetration.
1.3 This test method is not to be used to determine a percent ground cover value for RECPs, as the amount of light penetration
may include light passing through translucent material or reflecting off surfaces.
1.4 The values stated as a percentage are to be regarded as the standard. The values provided in foot-candlesfootcandles are for
information only.
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 safety, health, and healthenvironmental 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.

5. Significance and Use
5.1 Light penetration may be used to control the quality of many RECPs. Light penetration has not been proven to relate to field
performance for all materials.
5.2 The light penetration of RECPs may vary considerably, depending on the composite materials used in the matrix of the mat
or due to inconsistency within a given mat. To minimize variation, specific sample size and procedures are indicated in this test
method to help ensure comparable results.
5.3 This test method may be used to determine the effect of different composite materials and makeup of RECPs on the
penetration of light.
5.4 This test method may be used for acceptance testing of commercial shipments of RECPs. Comparative tests as directed in
5.4.1 may be advisable.
