Have you downloaded your free copy of the Bearing Selection Design White Paper? If so, you’re probably familiar with ASTM Testing Standards for plastic materials. Today we’ll provide a review of why these standards are an important consideration in bearing selection.
ASTM helps to ensure that only quality, raw materials are used to produce bearings and other industrial goods. The standards are highly-regarded throughout the plastic supply chain. Here are a few FAQs about this industry organization:
Common ASTM Standard Test Methods for classifying plastic bearings:
D149 Dielectric Strength
D150 Dielectric Constant and Dissipation Factor of Plastics
D256 Izod Impact
D638 Tensile Properties of Plastics
D648 Heat Deflection Temperature
D695 Compressive Properties of Rigid Plastics
D570 Water Absorption of Plastics
D7774 Flexural Fatigue Properties of Plastics
D790 Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials
D792 Specific Density & Gravity
D953 Bearing Strength of Plastics
D1822 Tensile Impact
D2990 Tensile, Compressive and Flexural Creep and Creep-Rupture of Plastics
