We do not feel that an interpretation is necessary\non this point, since your question involves grammatical construction.\nThroughout Part 192 the use of the word \"or\" between the last choice in a series and that\nimmediately preceding it, as in §192.285(b)(2), means that any one of the choices listed in the\nseries may be used. The word \"or\" is implied following each of the other choices in the series.\nYou also ask about the word \"deformed\" in §192.285(b)(2)(iii)(B) and particularly whether the\ndeformation shown in attachments to your letter provide an acceptable bend test. The rule\nrequires the joint area to be deformed by bending, torque, or impact, but does not specify either\nelastic or inelastic deformation. The attachments to your letter illustrate one method of producing\nan appropriate strain that should cause flows in such heat fusion joints to be readily observable.\nFor your assistance in further application of §192.285, we are enclosing copies of the notice and\nfinal rule with amendments, for Docket No. PS-54, which established this rule.\nWe hope that this answers your questions to your satisfaction.\nSincerely,\nRichard L. Beam\nAssociate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\nEnclosure\ndal\\192\\285\\83-09-13\n1","truncated":false,"body_characters":1698}
