G7/G7M

Standard Practice for Natural Weathering of Materials

active, Most Current
Publication Date: 1 July 2021
Status: active
Page Count: 7
ICS Code (Environmental testing): 19.040
scope:

This practice covers procedures to be followed for direct exposure of materials to the environment. Typically, this testing is performed on exposure racks tilted at a commonly used tilt angle from the horizontal (such as 5 or 45 degrees) and facing the equator. Other exposure orientations can be used.

This practice is not intended for the corrosion testing of bare metals, or for testing behind glass.

For corrosion testing, refer to Practice G50

For exposures behind glass, refer to Practice G24

Units-The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

This practice is technically equivalent to the parts of ISO 877-1 and -2 that describe direct exposures of specimens to the environment.

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.

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.
