New Guide for Statistical Sampling for Weathering Exposures

1. Scope

The promotion of knowledge, stimulation of research, and the development of standards related to the durability and performance of organic and inorganic nonmetallic materials, components and combined assemblies that are subjected to various environments.
These objectives will be implemented by the development and coordination of standards relating to nomenclature, standard conditions, methods and instrumentation associated with the aging, weathering biodeterioration, exposure to specific environments and accelerated or service testing of such materials, components and combined assemblies with other materials.
The Committee shall establish liaison with other ASTM Technical Committees with related interests. Where appropriate, the Committee will also assure that its standards are harmonized with related international standards.


sampling; statistics; weathering


There is currently no information provided to weathering practicioners about how to design studies (e.g., number of samples, impact of response measurement accuracy) that will provide statistically significant outcomes as well as provide possible consequences of not developing statistically sound studies.

The title and scope are in draft form and are under development within this ASTM Committee.
