Scope of standard 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 footcandles 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, 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.
