W. Schneider\nVice President - Engineering\nBonney Forge Division\nGulf + Western Manufacturing Company\nAllentown, Pennsylvania 18105\nDear Mr. Schneider:\nIn your letter of July 5, 1973, you asked for clarification concerning the use of the word\n\"prototype\" in Sections 192.149 and 192.505(d)(2) of Part 192, Title 49, Code of Federal\nRegulations.\nOur use of the word \"prototype\" in these Sections means the original pattern on which all similar\nsubsequent fittings of the same kind and size are based. In the case of bursting strength\nrequirements for a particular fitting made in accordance with certain design specifications, size,\nmaterial properties, and manufacturing process, such a new fitting would be tested to burst. After\nsatisfactory test, any number of like fittings would be expected to meet strength requirements for\nsuch a type fitting.\nIf there is a change in size, material, design specifications, manufacturing process, or any other\nthing that could affect the performance, it would be expected that such a change would\nnecessitate the testing of a new prototype.\nI trust this satisfactorily answers your question as to what constitutes a \"prototype.\"\nSincerely,\nSigned: De Leon\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\ndal\\192\\149\\73-08-10\n1","truncated":false,"body_characters":1308}
