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.

5 Apparatus5.1 Compressive testing machine, capable of a constant rate of crosshead movement, via a pair ofparallel plates (5.2), as appropriate to the nominal diameter of the pipe in conformance with Table 1, withsufficient force and travel to produce the specified diametric deflection (see Clause 8). 5.2 A pair of hard and rigid plates, through…

5 Apparatus5.1 Loading deviceA suitable device for applying the load is a lever-arm loading machine with an arm ratio between 4:1 and 10:1. A typical example of such a device is shown in Figure 2. The lever-arm ratio R is equal to L1/L2. When the lever-arm is fitted with the top specimen grip and the…

4 Principle A test specimen having a specified precut slit is subjected to a tearing force generated by the energy stored in a pendulum of specified dimensions. The energy expended in tearing the specimen is used to calculate the tear resistance of the specimen. 5 Apparatus The test machine shall be of the Elmendorf type…
