| Note: 1. Unless indicated otherwise, values shown are minimum average roll values determinate in accordance with ASTM D4759-02. 2. Nominal Value(s). 3. True resistance to elongation when initially subjected to a load determined in accordance with ASTM D6637 without deforming test materials under load before measuring such resistance or employing “secant” or “offset” tangent methods of measurement so as to overstate tensile properties. 4. Expressed as a comparison of GRI-GG2 strength to GRI-GG1 strength of the same sample. 5. Resistance to bending force determined in accordance with ASTM D1388 mod. 6. Flammability resistance determined from vertical and horizontal flame in accordance with 30 CFR, Part 7, Subpart A & B and ASTP5011-Standardized Small Scale Flame Test Procedure for the Acceptance of Roof-Rib Grid. 7. Roll widths of 1.5-3.9m and lengths of up to 100m are available to order. |
