Scope
Main Technical Content: 5. Technical Requirements 5.1 Raw Material Requirements (MCMP) The material used for square pipes is a multi-component modified polyvinyl chloride resin, which is extruded into new composite reinforced pipes that meet the requirements of this standard. The modified material shall not contain plasticizers, and the content of fillers shall not exceed 5%. 5.2 Product Requirements 5.2.1 Color, Appearance, and Dimensions 5.2.1.1 Color The color of the pipes is generally orange. Other colors shall be determined by mutual agreement between the supplier and the buyer, and the color should be uniform and consistent. 5.2.1.2 Appearance (MCMP) The inner and outer walls of the square pipes shall not have bubbles, cracks, obvious impurities, decomposition discoloration lines, or irregular ripples. The inner wall should be smooth and flat. 5.2.1.3 Dimensions and Tolerances The dimensions and tolerances shall comply with Table 1. The length is generally 6.2m, but it can also be determined by mutual agreement between the supplier and the buyer. (MCMP) The length of the square pipes shall include the length of the circular pipe joints, and the maximum negative deviation of the length shall be 0.5% of the length. 5.3 Technical Performance 5.3.1 The technical performance of (MCMP) square pipes shall comply with Table 2. Table 2 Technical Performance Requirements for Modified Polyvinyl Chloride (MCMP) Square Double-Wall Corrugated Pipes Item Unit Technical Indicator Test Method Density kg/m3 ≤1500 6.3 Vicat Softening Temperature °C ≥80 6.4 Oven Test - No delamination or cracks 6.5 Flat Test - Compressed until the inner walls of the pipes touch each other, and the sample shall not show cracking, delamination, or peeling 6.6 Resistance to External Pressure Load NS1 ≥4000 6.7 S2 ≥5500 Drop Hammer Impact Test -10/10 Pass 6.8 Vertical Flammability - V-0, extinguishes immediately after r
