New ASTM standard covers testing for crossarms in towers

January 25, 2016 – ASTM International says one of its new standards will help determine “important attributes for polymer crossarms that are an integral part of electrical distribution structures.”

The standard allows experts to establish design and strength criteria that can be used throughout the engineering community. It has been published as D8019, Test Methods for Determining the Full Section Flexural Modulus and Bending Strength of Fiber Reinforced Polymer Crossarms Assembled with Center Mount Brackets.

Manufacturers, engineers and those who work in standards departments in the electric power transmission and distribution industry will use the new standard to write specifications and for determining the strength and stiffness of pultruded crossarms, according to ASTM.

ASTM’s subcommittee on reinforced thermosetting plastics (D20.18) said it intends to develop more standards in this area.
