: A global standard compromise angle for assessing general weathering.
ASTM G7 is utilized across a broad spectrum of industries that manufacture goods meant for outdoor deployment:
Atmospheric weathering poses a continuous threat to the structural integrity, appearance, and lifespan of nonmetallic materials. Polymers, coatings, plastics, and composites degrade when exposed to outdoor elements like solar radiation, moisture, and temperature fluctuations. To evaluate how these materials withstand real-world conditions, industries rely on standardized testing protocols.

The American National Standards Institute (ANSI) is a major reseller of ASTM standards. They offer the standard as well, often with options for a "Redline" (PDF bundle showing changes from the previous version). You can find on their webstore.
The standard universal angle for general weathering.
: Ground-level ozone, acid rain, and industrial emissions chemically react with material surfaces, exacerbating solar degradation. 📐 Structural and Positioning Requirements

ASTM G7 is a testing standard managed by ASTM International. It provides guidelines for exposing nonmetallic materials—such as plastics, paints, coatings, and rubber—to natural outdoor elements.
The protocol dictates the Standard Practice for Natural Weathering of Materials , focusing on the direct exposure of nonmetallic materials to outdoor environments. Published and maintained by ASTM International, this globally recognized standard sets the baseline framework for evaluating how materials like plastics, coatings, paints, and polymers degrade under real-world atmospheric conditions. Navigating the document's intricacies via an ASTM G7 PDF helps engineers, quality control specialists, and material scientists understand natural material degradation without relying solely on artificial laboratory simulations. 📋 What is ASTM G7?
