ASTM G7 isn't just about sticking a sample in a backyard. It requires a high level of scientific control to ensure data is "defensible": Specimen Control

ASTM G7 is a standard test method developed by the American Society for Testing and Materials (ASTM) for "Practice for Outdoor Exposure Testing of Paints". However, the focus of this article will be on ASTM G7 - "Standard Practice for Laboratory Corrosion Testing". This standard provides a comprehensive framework for conducting laboratory corrosion tests on metallic materials, including metals, alloys, and coatings. The test method involves exposing the material to a controlled corrosive environment, which simulates real-world conditions. astm g7 pdf

Environmental data like rainfall, humidity, and temperature. ASTM G7 isn't just about sticking a sample in a backyard

The primary goal of ASTM G7 is to provide a standardized technique for evaluating how —such as plastics, coatings, and textiles—react to direct outdoor environmental exposure. The primary goal of ASTM G7 is to

Data to include in the final report: GPS coordinates of test site, orientation, start/end dates, visual ratings (chalking, cracking, blistering per ASTM D714), and any anomalous weather events (e.g., hurricanes or ice storms).
