1、Designation: D 1014 02Standard Practice forConducting Exterior Exposure Tests of Paints and Coatingson Metal Substrates1This standard is issued under the fixed designation D 1014; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the
2、 year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This practice covers proced

Therefore, it cannotbe assumed that results from one exposure in a single locationwill be useful for determining relative durability in a differentlocati

Exposures in several locations with different climateswhich represent a broad range of anticipated service conditionsare recommended.4.2.1 Because of year-to-year climatological variations, re-sults from a single exposure test cannot be used to predict theabsolute rate at which a material degrad

This can cause large differences in the apparent rate ofdegradation in many polymers. Comparing results for materialsexposed for s
