Description: Experimentally and commercially produced laminated M-19 crossarms were tested by standard Rural Electrification Administration (REA) crossarm tests. The laminated crossarms, produced by laminating veneer and by laminating solid-sawn dimension stock, generally performed satisfactorily according to REA specified standards. Materials tested are described and results on standarized tests are summarized. The objective of this work was to provide indications of performance trends. Statistically valid performance comparisons between the materials tested were not possible because of the limited number of samples tested.
