8.4.2 Flexing test8.4.2.1 Apparatus8.4.2.1.1 Testing device, as illustrated in Figure 45. The test piece shall be guided in such a way that on one side it can be bent at an angle of 90° about a mandrel with a radius of 15 mm. 8.4.2.1.2 Cutting tool, as defined in Figure C.2 of ISO 5423:1992.8.4.2.1.3 Measuring…
Methods for characterization of slow crack growth Pipes made of polyethylene such as PE80, PE100 or the improved PE100RC display differing levels of sensitivity to slow crack growth. The terms “Environmental Stress Cracking” (ESC) and “Slow Crack Growth” (SCG) are used to describe this behavior. A failure of this type takes place well below the…
G.1 GeneralThe test consists of verifying the strength of the FJC by the impact of a punch of defined shape falling directly onto the coating from a fixed height and at a fixed temperature. The test shall be carried out on pipes or cut samples. This test shall not be carried out on pipes with…
7 Test equipment7.1 GeneralThe equipment used for all measurements shall be traceable to national or International Standards. They shall be calibrated within suitable intervals.7.2 Installation and verificationThe testing machine shall be installed and verified in accordance with ISO 148-2.7.3 StrikerThe striker geometry shall be specified as being either the 2 mm striker or the 8…
Paraffinic waxes are used for many industrial and consumer applications. We manufacture test and analysis equipment for paraffin wax to determine a wide range of chemical and physical properties. Paraffin was analysis can include purity, contamination, trace components, melting point, oil content and more. Here lets see some of these tests in brief. A- Drop…
5 Apparatus The test assembly shall include the following main elements: NOTE 1 The test temperature (40°C or 80°C) is specified in the relevant product- or system standard. NOTE 2 1 ppb = 1 g/m3. 5.1 Oven, capable of maintaining a constant temperature of (40 ± 0,5) °C and/or (80 ± 0,5) °C. 5.2 Test…
Cord guards shall have adequate mechanical strength and shall retain these properties throughout extended normal use. Compliance is checked by the following test:The part of the tool comprising the cable entry, fitted with the cord guard and the flexible cable or cord for which the tool is designed, is fixed in the oscillating member of…
6. Requirements 6.1 Workmanship—The pipe shall be homogeneous throughout and free of visible cracks, holes, foreign inclusions, or other defects. The pipe shall be as uniform as commercially practicable in color, opacity, density, and other physical properties. See 5.1.2. 6.2 Dimensions and Tolerances: 6.2.1 Inside Diameters—The inside diameters and tolerances shall be as shown in…
4.2 Apparatus Forced-air-circulation oven, maintained at 70 °C ± 2 °C, capable of re-establishing that temperature within five minutes after insertion of test pieces. NOTE — A constant-temperature bath may be used instead of the oven, provided it has the same thermal capabilities as specified for the oven. 4.3 Test pieces Five sections of the…
Apparatus6.1 Grips—Grips for SIM and R+H tests should be the same as the grips for ultimate strength tensile tests. Neither slippage nor excessive stress causing premature rupture should be allowed to occur.6.2 Testing Machine—A universal testing machine or a dead-weight loading system with the following capabilities and accessories shall be used for testing.6.2.1 Load measurement…
