Consensus i

The immediate need for standard specificati
19、ons was answered by the issuance, in 1959, of Commercial Standards CS 221-59 for bathtubs and CS 222-59 for shower receptors. These stan- dards served as the basis of product acceptance by the Federal Housing Administration (FHA) and code writing agencies. In 1962 the development of a needed industr
20、y standard was undertaken by the NAHB Research Institute and a Reinforced Plastics Industry Advisory Board with the cooperation and assistance of the Society of the Plastics Industry. In July 1963, the NAHB Research Institute issued a new standard for tub-shower units which constituted an extensive
21、revision of CS 221-59 and was the first performance-type standard for such products. In December 1965, the NAHB Research Foundation, Inc., continuing the work of the NAHB Research Institute, issued a revised standard for bathtub units and a standard for shower recep- tors and stalls. These standards
22、 were considered by those most interested to be worthy of approval as an American National Standard, and the need for their application nationally was self-evident. Accordingly, they were submitted to the Standards Institute in 1965 and approved on April 5, 1967 as American National Standard for Gel
23、-Coated Glass-Fiber Reinforced Polyester Resin Bathtub Units, Z124.1-1967 and Gel-Coated Fiberglass Reinforced Polyester Resin Shower Receptors and Shower Stalls, Z124.2-1967. The sponsor also asked for the establishment of an American National Standards Committee, which was approved as American Nat
24、ional Standards Committee Z124. In October 1978, the International Association of Plumbing and Mechanical Officials (IAPMO) assumed the secretariats position to continue the work already in progress. The continuation of work resulted in the revision and updating of Z124.1 for Plastic Bathtubs and Z1
25、24.2 for Plastic Shower Receptors and Shower Stalls. A new standard for Plastic Lavatories, which had been started by a Task Group in early 1975, was also completed and forwarded to American National Standards Institute in September 1979. The formal adoption date was May 21, 1980, and resulted in Am
26、erican National Standard Z124.3 for Plastic Lavatories. At the request of HUD, a Task Committee developed a standard for Plastic Water Closet Bowls and Tanks. It was completed and forwarded to ANSI and formally adopted May 30, 1983, as American National Standard Z124.4. The Standard for Plastic Toil
27、et (Water Closet) Seats which was started in November 8, 1983 was completed and forwarded to the American National Standards Institute on February 15, 1989. The formal adoption date was August 24, 1989 and resulted in American National Standards Institute, Standard Z124.5 for Plastic Toilet (Water C
28、losets) Seats. The Standard for Plastic Sinks which was started in April 1986 was completed and forwarded to American National Standards Institute on July 1989. The formal adoption date was December 13, 1990 and resulted in American National Standard Z124.6 for Plastic Sinks. The Standard for Plasti
29、c Bathtub Liners which was started in 1985 was completed and for- warded to the American National Standards Institute in June, 1990. The formal adoption date was October, 1990 and resulted in American National Standards Institute, Standard Z124.8 for Plastic Bathtub Liners. The Standard for Plastic
30、Urinal Fixtures which was started in November, 1990 was completed and forwarded to the American National Standard Institute in November, 1993. The formal adoption date was January 25, 1994 and resulted in American National Standards Institute iii Licensed to Sarah Zhou. ANSI order X_63851. Downloade

The Z124 Committee had grown from the original 1962 Committee of eleven industry members to a consensus Committee of thirty-four members. This standard was processed and approved for subm
33、ittal to ANSI by American National Standards Committee on Synthetic Organic Materials in Plumbing Fixtures, Z124.
