— The effect of specimen size on fracture toughness of a pipe‐grade high density polyethylene has been examined using the J integral approach. It was found that the size requirements set up by common standards appear inadequate for this material. Measurements at low temperatures, at which a plane strain fracture toughness value could be obtained, turned out to be very effective in establishing a more appropriate size requirement for this material.
