6. Apparatus 6.1 Specimen Clamp and Striking Edge: 6.1.1 Type A: 6.1.1.1 Design the specimen clamp to hold the specimen or specimens as a cantilever beam. Each individual specimen shall be firmly and securely held in a separate clamp. The striking edge shall be hardened steel, have a radius of 1.6 +- 0.1 mm and…
4 PrincipleAir is compressed by the weight of a vertical cylinder floating in a liquid. A test piece is in contact with thecompressed air and the cylinder falls steadily as air passes through the test piece. The time for a givenvolume of air to pass through the test piece is measured and from this the…
9.1 Type tests and test sequences 9.1.1 The characteristics of circuit-breakers are verified by means of type tests. Type tests required by this standard are listed in table 8. 9.2 Test conditions The circuit-breaker is mounted individually, vertically and in free air at an ambient temperature between 20 °C and 25 °C, unless otherwise specified,…
8.9 Test 9 — Corner drop test8.9.1 PurposeThe purpose of this test is to determine the diagonal rigidity of the top deck of the pallet and its resistance to impact. 8.9.2 ProcedureMark the two measuring points, A and B, as shown in Figure 9 at approximately 50 mm from the corners of the pallet. While…
4 PrincipleThe impact strength of suitably sized test specimens is determined by striking them with a lubricated weighted striker dropped vertically from a known height. The test specimen is impacted at its centre by a striker, perpendicular to the surface of the specimen.Two methods of adjusting the energy at impact are permitted: altering the mass…
8.1.2 When the specified time period has been attained, remove the test specimens and determine the frost point in accordance with Test Method E 546. Observe for chemical dew point.8.2 Accelerated Weather Cycle Test:8.2.1 Place the test specimens that were tested in accordance with 8.1 in the accelerated weather cycle test apparatus. Mount the specimens…
A.13 Flexibility of the coating A.13.1 EquipmentThe equipment shall consist of the following:A.13.1.1 Hydraulic press.A.13.1.2 Bending mandrels, with fixed radii.A.13.1.3 Freezer.A.13.1.4 Strain gauges (if applicable).A.13.2 Test specimensLaboratory-coated test specimens shall be approximately 6,4 mm × 25 mm with a minimum length of 200 mm.Specimens from test rings shall be the pipe wall thickness with a…
8.1 Test 1 — Bending tests8.1.1 PurposeThe purpose of these tests is to determine the bending strength (test 1a) and bending stiffness (test 1b) of the pallet in racking situations. 8.1.2 Procedure8.1.2.1 In order to establish the weakest pallet support dimension, test one pallet across the length of thepallet and then a second pallet across…
In this post you will know step by step how to start the high pressure test unit of 1000 bar maximum pressure. 1- When you unpack the machine from pallet, first connect compressed air line to the 6mm air connector in the right side of machine(as shown in the picture below).6 bar is enough for…
