6 Apparatus6.1 Tensile Testing Machine, with a reversible chart, complying with the requirements listed for Method A of Test Methods D882 with grips satisfactory for the purpose. Refer to section on grips in Test Methods D882.6.2 Specimen Cutter, capable of producing nick-free 1±0.001 in. (25.4±0.03 mm) testing strips, with a precision of 1 ± 0.001…

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…

14.2 Test conditions During the tests for IPXl to IPX6 the water temperature should not differ by more than 5 K from the temperature of the specimen under test. If the water temperature is more than 5 K below the temperature of the specimen a pressure balance shall be provided for the enclosure. Adequate safety…

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,…

7 Mechanical characteristics 7.1 Mechanical characteristics of pipes 7.1.1 General requirements When tested in accordance with the test method as specified in table 16, using the indicated parameters, the pipe shall have mechanical characteristics conforming to one of the requirements given in table 16. 7.1.3 Mechanical characteristics of fittingsFor application area BD the fittings shall…

7.3 Micrometer, for measurement of specimen thickness. Ensure that the accuracy is 1 % of the average thickness of the specimens used. See Test Methods D5947 for descriptions of suitable micrometers.
