D4803-24 – Standard Test Method Technical Guide
🏠 Scope and Application
ASTM D4803-24 provides a standard test method for predicting heat buildup in rigid and flexible PVC building products. This heat buildup is above ambient air temperature and is relative to black, occurring due to absorption of the sun’s energy. The method is expected to be applicable to all types of colored plastics once data is submitted for review.
Products covered include rigid PVC siding (D3679), soffit (D4477), exterior profiles for fencing and railing (F964), windows and doors (D4726), and building compounds (D4216). The standard references numerous other ASTM documents for terminology and specifications.
Values are stated in inch-pound units as standard, with SI conversions provided in parentheses for information only.
💡 This test method is intended for PVC but may be extended to other plastics upon data submission.
⚙️ Test Procedure and Referenced Standards
The test method predicts heat buildup through absorption of simulated solar radiation. Key referenced documents ensure uniformity across testing.
