Anotace textu normy ASTM C923/C923M-20(2025) :

This specification covers resilient connectors between reinforced concrete manhole structures, pipes, and laterals. Resilient materials for connectors and filler rings shall be manufactured from natural or synthetic rubber and shall conform to the prescribed requirements. Mechanical devices shall be made from a material or materials in combination that will ensure durability, strength, resistance to corrosion, and have properties that will ensure continued resistance to leakage. The design of pipe connectors and pipe stubs are specified. The physical properties and chemical composition shall conform to the required tests for chemical resistance, tensile strength, elongation at break, hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance.
