The NM.3 Standard provides specifications for nonmetallic materials (except wood, nonfibrous glass, and concrete) and, in conformance with the requirements of the individual construction standards, methodologies, design values, limits, and cautions on the use of materials. Similar to the function that Section II of the Boiler and Pressure Vessel Code (BPVC) serves for metallic materials, ASME NM.3 provides a central location for material specifications, allowable stress values and physical properties of non-metallic materials.

This Standard is divided into three parts:

ASME NM.3.1 Part 1 – Thermoplastic Material Specifications
ASME NM.3.2 Part 2 – Reinforced Thermoset Plastic Material Specifications
ASME NM.3.3 Part 3 – Properties

ASME NM.3.3 contains tables and data sheets for allowable stresses, mechanical properties (e.g., tensile and yield strength), and physical properties (e.g., coefficient of thermal expansion and modulus of elasticity) for nonmetallic materials.
