ASTM D2467:20 pdf download.Standard Specification for Poly(Vinyl Chloride) (PvC) Plastic Pipe Fittings,Schedule 80.
3. Terminology
3.1 General—Definitions are in accordance with Terminology F412 and abbreviations are in accordance with Terminology D1600, unless otherwise indicated. The abbreviation for poly(vinyl chloride) plastic is PVC.
4. Classification
4.1 General—This specification covers Schedule 80 Pvc pipe fittings, socket-type, made from four vc plastic compounds and intended for use with Iron Pipe Size (IPS) outside-diameter plastic pipe. (See Specification D1785.)
4.1.1 Fittings covered by this specification are normally molded. In-line fittings, such as couplings, unions, bushings, caps. nipples, and the like, shall be molded or machined from extruded stock.
4.1.2 Fittings fabricated by back welding or butt fusion are not included in this specification.
5. Materials and Manufacture
5.1 This specification covers PVC pipe fittings made from fire PVC plastics as classified in Specification Dl784. These are PVC 12454, 11443, and 14333.
5.2 Compound—The PVC plastic compound shall meet the requirements of PVC 12454, 11443, or 14333, as described in Specification Dl 784.
5.3 Rework Material—The manufacturers shall use only their own clean rework fitting material and the fittings procluced shall meet all the requirements of this specification.
6. Requirements
6. 1 Dimensions and Tolerances:
6.1.1 Fitting sockets inside diameters (waterways), minimum wall thicknesses, and dimensions shall be as shown in Tables 1-5 when measured in accordance with Test Method
D2122.
6. 1 .2 When multistep reducer bushings are cored out, the inner socket shall be reinft)rced from the outer wall by a minimum of three ribs extending from the top of the inner socket to the deepest extremity of the coring. The transition from D to DJ (Table 4) shall be straight, tapered as shown, or radiused. A positive taper in the same direction of the taper in the socket on the outside diameter of the bushing is optional (see XAIXB in Table 3). Any point measured along the outside diameter of the bushing (between points XA and XB) shall not fall below minimum pipe OD.
6. 1 .3 The minimum wall thickness of fittings shall be 1 25 % of the minimum wall thickness of the corresponding size of Schedule 80 pipe for which they are designed to be used, except that for the socket, the wall thickness shall be at least equal to the minimum wall thickness of the corresponding size of Schedule 80 pipe.
6.1.4 The minimum inside diameter of the fittings shall
be not less than the minimum specified inside diameter of the corresponding size of Schedule 80 pipe. This is calculated as follows.
