4 PrincipleA cylindrical rubber test piece is made to slide over an abrasive sheet of specified abrasive grade at aspecified contact pressure over a given distance. The test piece may be non-rotating or rotating during the test.Abrasion takes place over one of the end surfaces of the cylindrical test piece (see Figure 1). The abrasivesheet…
4.2 Pipe materialWhen tested in accordance with the test method as specified in Table 1, using the indicated parameters, the pipe material shall have characteristics conforming to the requirements given in Table 1.The pipe material shall be tested in the form of a pipe. 4.3 Fitting material When tested in accordance with the test method…
1.6 This test method is applicable to the measurement of thermal transmission through a wide range of specimen properties and environmental conditions. The method has been used at ambient conditions of 10 to 40°C with thicknesses up to approximately 250 mm, and with plate temperatures from –195°C to 540°C at 25-mm thickness (5, 6).1.7 This…
12 Piston/plunger assembly 12.1 Design The design of the plunger and push-button of the syringe shall be such that, when the barrel is held in one hand, the plunger can be depressed by the thumb of that hand. When tested in accordance with annex B , the piston shall not become detached from the plunger….
5 Apparatus5.1 Heating equipment, consisting of one of the following (5.1.1, 5.1.2 or 5.1.3) that will accept aminimum of two test frame assemblies and a cooling device (5.1.4).The heating equipment shall be provided with means of temperature control, enabling the temperatureto be raised at a uniform rate of (50 ± 5) K/h or (120 ±…
2 PrincipleSmall samples of raw-material pellet or material removed from the pipe or fitting are heated and compressed between microscope slides. Alternatively, a microtome slice can be taken.The specimens produced are examined microscopically and the sizes of particles and agglomerates are measured, recorded and graded by comparison with a tabulated grading system (see Table A.1).A…
4 Material 4.1 PP-compound The compound for pipes and fittings shall be PP-base material (homopoiymer or copoiymer) to which are added those additives that are needed to facilitate the manufacture of components conforming to the requirements given in this standard. In orderto conform to national requirements on fire regulations other additives may be used. Fabricated…
5 Apparatus5.1 Test machineThe principles, characteristics and verification of suitable test machines are detailed in ISO 13802. ISO 13802 describes partial verification and full verification. In the case of full verification, some items are difficult to verify when the apparatus is assembled. Such verifications are assumed to be incumbent on the manufacturer.5.2 Micrometers and gaugesMicrometers…
Determining the bond strength of coatings such as plastic welding, metal plating, and thermal spray coatings, is an essential aspect of assessing the products’ overall quality. Peel testing adhesion bond strength is done to understand the strength of the adhesion coating to the second material. For example, the clothing industry tests the bonding strength of…
ISO 9073 series of standards defines properties of Non wovens as below parts: 5 Important tests to the end use applications Nonwovens testing of physical and mechanical properties are essential to determining their end-use applications. For example, if a nonwoven has high absorptive capacity, it could potentially be used in an advanced wound care application,…
