D2830-96 – Standard Test Method Technical Guide
📐 Specimen Geometry and Materials
This test method provides for the determination of the relative exterior durability of factory-primed wood and wood-based substrates with representative finish coats when exposed to the weather. The values stated in SI units are to be regarded as the standard.
The standard apparatus is a vertical (90° from horizontal) test fence constructed in accordance with the requirements of Practice D 1006. Test panels must be of a specific preprimed substrate and meet the following geometric requirements:
| 🟦 Feature | 📏 Specification |
|---|---|
| Panel Length (minimum) | 910 mm (3 ft) |
| Panel Width (minimum) | 150 mm (6 in.) |
| Substrate Type | Factory-Primed Wood or Wood-Based |
| Finish Coat 1 | Oil/Alkyd, fume resistant (TT-P-102) |
| Finish Coat 2 | Resin Latex, emulsion type for wood (TT-P-96b) |
