WebFor elastomeric materials, the Rubber Manufacturers Association (RMA) publishes tolerance tables based on material type, thickness, width, length, and other variables (such as wall thickness for tubing). Different types of elastomeric materials belong to different RMA classes. For example, RMA Class ATH1 defines die cutting WebDrawing designation “A2” tolerances indicate a precision molded rubber product. Molds must be precision machined and kept in good repair. While measurement methods may be simpler than with drawing designation “A1” high precision for molded rubber products, careful inspection will usually be required.
