4 PrincipleIt is possible to determine the ash of an organic material by three main methods:a) Direct calcination, i.e. by burning the organic matter and heating the residue at high temperature untilconstant mass is reached (method A).b) Calcination after sulfation, which may be carried out by two different procedures:⎯ With sulfuric acid treatment after burning,…

For the valued customers note below brands used as internal parts with high quality. 1- Main pump: Bertollini Italy 2- Pressure sensors: WIKA Germany 3- Solenoid valves: ODE Italy…
1- Placement Place the machine in rugged stable table 2- Compressed air line From the back panel of the machine, connect compressed air line 3- Using pneumatic lifter, bring up the elevator to see inside the bath. Be noted for bringing this up you dont need to connect power. Before filling the tank with silicone…
5 Pendulum method5.1 Apparatus5.1.1 GeneralThe rebound resilience shall be measured by means of an apparatus consisting of a pendulum-like onedegree-of-freedom mechanical oscillatory device and a heavy and secure test piece holder.The two items shall be suitably fixed together for rebound resilience measurements, and either item can be removed for purposes of adjustment or checking of…
10.2 Compression testReplacement:10.2.1 Conduits are subjected to a compression test.NOTE: Compression test on fittings is under considerationThe test for conduits containing non-metallic materials is not started until 10 days after manufacture.10.2.2 Samples are (200 ± 5) mm long. 10.2.3 Before the test, the outside and inside diameters of the samples are measured as specified in…
25 Method F5: Water penetration25.1 ObjectThis test applies to continuously water-blocked cables. The purpose is to determine the ability of a cable to block water migration along a specified length. Compliance shall be checked on samples of cable using one of the two following methods (F5A or F5B), as stated in the detail specification. Method…
6.5 Tension 6.5.1 Three samples of MPT shall withstand a tension of 156 N (35 Ibf) for one minute applied in accordance with 6.5.5 – 6.5.6 Each sample shall be approximately 457 mm (18 inches) in length Following the test, there shall be no splits, cracks, tears, separation of convolutions, or other openings when it…
First thing we need to do is to analyze pure polymer. In this example, polymers A and B are heated up in DSC, and the heat for melting is recorded. It is a specific enthalpy meaning measurement is presented as per mg of material. We use this information to quantify the mixture contents. Here is…
