T/SPUIA 0001-2020 Polyurethane rigid foam for building insulation board

Scope

Main Technical Content: I. General Requirements 1. The appearance of the product should be smooth, without cracks, twisting, obvious indentations and protrusions, stains, or damage. There should be no sharp edges or corners that hinder use. The board edges should be neat and free from burrs or cracked edges. The warping of the board should not exceed 1.0%. 2. The basic performance indicators of polyurethane reinforced insulation boards should meet the requirements of Table 1: **Table 1: Basic Performance Requirements for Polyurethane Reinforced Insulation Boards** **Item** **C1/C2 Type** **H Type** **Apparent Density (kg/m3)** **≥35** **≥55** **Thermal Conductivity at 23°C (W/m·K)** **≤0.021** **Dimensional Stability (%)** **≤1.0** **Closed-cell Rate (%)** **≥90** **≥95** **Oxygen Index** **≥26** II. For Roofing and Floor Applications 1. The allowable dimensional deviations should meet the requirements of Table 2: **Table 2: Dimensional Tolerances for Polyurethane Reinforced Insulation Boards Used for Roofing and Flooring** **Item** **Allowable Deviation (mm)** **Length** **±2.0** **Width** **±2.0** **Thickness ≤50mm** **+1.5** **0.0** **≥50mm** **+2.0** **0.0** **Diagonal** **3** **Board Edge Straightness** **2** **Board Surface Flatness** **1** **Note:** - The allowable deviation values are based on a standard board (1200mm × 600mm). Deviations for other sizes should be agreed upon by the supplier and buyer. - The physical and mechanical performance indicators should meet the requirements of Table 3: **Table 3: Physical and Mechanical Performance Indicators for Polyurethane Reinforced Insulation Boards Used for Roofing and Flooring** **Item** **Allowable Deviation (mm)** **Length** **±2.0** **Width** **±2.0** **Thickness ≤50mm*
