Revise or eliminate Table 4 which specifies Lay Lengths or G dimensions for Tees and Elbows. The existing table we believe is not intended to be an absolute minimum given there is no tolerance specified. Other similiar socket fusion fitting standards such as the one for Polypropylene do not even have such a table and leave it up to the designer to determine the minimum lay length dimensions and still meet all other performance and socket fusion dimensional requirements. The principal goal of the 1st task group in Toronto is to solicit input from fitting manufacturers who currently produce to this standard.
