less than 0.85. and no conditioned specimen shall crack or collapse before budding or the 60 percent point is reached.
5.7 Watertightness
5.7.1 Coupled conduit and fittings shall not leak when tested in accordance with 5.7.2. Expansion pnt marked in accordance with 6.3 do not require this test.
5.7.2 A 300 ±3 mm (12.0 ±0.125 in) length of conduit shall be inserted into the integral coupling of another length of conduit having a total length of 300 ±3 mm (12.0 0.125 in). according to the manufacturer’s installation instructions.
5.7.3 In the case of an elbow or fitting. one or two 300 ±3 mm (12.0 ±0.125 in) lengths of conduit. as appropriate, shall be inserted into the coupling according to the manufacturer’s instructions. One end of the assembly shall be capped with a suitable enclosure. The assembly shall be placed in the vertical position, with the sealed end at the bottom, and filled with tap water. After a minimum of 4 h, the specimen shall be visually examined to determine any evidence of leakage.
5.8 Joint separation
5.8.1 A joint (conduit and socket) shall not separate when tested in accordance with 5.8.2.
5.8.2 Two joints in each trade size shall be assembled as intended. A gasketed joint shall be subjected to an axial pull 01 444 N (100 lbf), applied to the assembly for 5 mm, intending to pull the conduit Out of the socket. A mechanical or threaded joint shall be subjected to an axial pull of 4448 N (1000 lbf), applied to the assembly for 1 mm, and tending to pull the conduit Out of the socket. An adhesively secured joint shall be subjected to an axial pull of 6670 N (1500 lbf), applied to the assembly for 1 mm, and tending to pull the conduit out of the socket.
5.9 Flattening resistance
5.9.1 The vertical inside diameter of conduit shall not decrease by more than the value indicated in Table
19 when tested in accordance with 59.2.
5.9.2 Two specimens shall be tested. Each specimen shall be 75 ±3 mm (3 ±0.125 in) long. The vertical inside diameter of each specimen shall be measured and the value recorded. The specimens shall be placed horizontally side by side between the 2 steel platens of a static load test as shown in Figure 5. The specimens shall be placed such that the measured vertical inside diameter is in the vertical position. No part of the specimen shall extend beyond either platen. A test mass of 45 kg (100 lb). including the mass of the upper platen. shall be symmetrically applied. This assembly shall be maintained at a temperature of 110 ±1 C (230 ±2F) for a period of 24 h. The specimens shall be allowed to cool, with the test mass removed, at 23 ±2C (73 ±4 F) for a minimum of 1 h. The vertical inside diameter shall be re-measured, recorded, and the actual decrease calculated and recorded.UL 2515-2019 pdf free download.
