Beside all other ways of laboratory sample preparations like: One economic sample preparation method uses a manual milling machine and templates for different tensile samples. In this method, the customer needs to inform us about the sample types that are going to be produced with this machine, and we will provide templates for them. TEMPCUT…

9.3 Determination of Frost State and No-Frost State:9.3.1 Charge the frost/dew point apparatus with dry ice as described in 9.1 or 9.2.9.3.2 Clean both exterior surfaces of the specimen.9.3.3 Place a piece of silver-colored aluminumized polyester film3 (highly reflective mirror surface, not thicker than 0.08 mm (0.003 in.) and 25 mm (1 in.) in diameter…
6 Test rig and fixtures 6.1 Test rig The test rig shall be a compression or tensile testing machine or similar (shear testing) machine of sufficient capacity to apply the shearing load by activating a ram. The test rig shall provide equipment to register the exact load applied at the instant of shear failure. The…
H.1 GeneralThe test consists of measuring the indentation of a punch into the FJC under fixed conditions of temperature and load. H.2 EquipmentH.2.1 Chamber or bath, thermostatically controlled to ± 2°C;H.2.2 Penetrometer, comprised of⎯ a cylindrical indenter on the top of which is mounted a weight; the assembly, indenter plus weight, shallproduce a pressure in…
Calibration offset value. Be noted after setting of proper offset value, don’t forget to “ENTER”. Unless the value will not be saved.
Scope This standard specifies a method for testing the resistance of joints to pressure cycling. It is applicable to piping systems based on rigid or flexible thermoplastics pipes intended to be used in hot and cold water applications. 3 Apparatus 3.1 Pressurizing device, capable of applying and regulating the water pressure in the test piece…
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…
4.2 ApparatusThe following apparatus shall be used:a) a device for generating a controlled amount of ozone;b) a means for circulating ozonized air under controlled conditions of humidity andtemperature through a chamber containing the test pieces to be tested;c) a means for the determination of ozone concentration;d) a suitable device for the clamping and elongation of…
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…
