UL 2515A:2016 pdf free download – STANDARD FOR SAFETY Supplemental Requirements for Extra Heavy Wall Reinforced Thermosetting Resin Conduit (RTRC) and Fittings.
4.3.4.2 The test fixture shall have rigid bases, located at the correct extended support distance, at each end of the fixture. The bases shall be designed to prevent movement of the specimen for the duration of the test. The bases shall support V-block clamps fastened to each base and aligned to the extended support distance.
4.3.4.3 A flexible loading strap having a width of 50 ±3 mm (2.0 ±0.125 inches) shall be provided for center-point loading. The load medium shall be sand, steel shot or equivalent. (See Figure 4.3).
4.3.5 Test procedure
4.3.5.1 The specimen shall be placed in the fixture and set up for the specified conduit and extended support distance.
4.3.5.2 Both ends of the specimen shall be securely tightened in the support clamps so that movement of the specimen is prevented during the test period.
4.3.5.3 The specimen shall be pre-loaded with the test load for 10 minutes. The test load shall be removed and measurements for zero deflection shall be recorded. The test load shall then be reapplied. The initial deflection measurement shall be recorded. Deflection shall then be recorded at 12 ±3 hour intervals for 168 hours (7 days).
5 Markings
5.1 All of the markings mentioned in 5.2 — 5.4 shall be clearly legible and durable. Additional markings are acceptable if they do not conflict with those specified in this standard.
5.2 The outer surface of every straight length of conduit, and every elbow and other bend made from and for use with such conduit shall be marked with the following:
a) “Reinforced Thermosetting Resin Conduit”, “RTRC”, or equivalent wording;
b) The trade size (metric designator) of the conduit;
c) The name or trademark of the manufacturer or with any other distinctive marking by means of which the organization responsible for the product can readily be identified;
d) “XW-IPS”, “XW-ID”;
e) “For Use – 40°C to 110°C”;
f) “Aboveground”, “AG”, or equivalent wording;
g) Expansion joints which are not subjected to the test in Clause 5.7 of the Standard for Aboveground Reinforced Thermosetting Resin Conduit (RTRC) and Fittings, UL 2515, shall be marked “FOR NON WATERTIGHT USAGE”.
h) Conduit straight lengths that comply with the Extended Support Distance Test described in 4.3 shall be marked “Suitable for use at a support distance of ____ m” (“ ft”) or an equivalent wording.
5.3 Where the manufacturer produces conduit or elbows or fittings at more than one factory, the outer surface of each finished straight length of conduit and each elbow and fitting shall be marked with a distinctive designation (which may be in code) by means of which the conduit or fitting is identified as the product of a particular factory. The meaning of any coded identification shall be made available.
