(a) Criteria for Acceptance. (1) At least three specimens of cargo compartment sidewall or ceiling liner panels must be tested. (2) Each specimen tested must simulate the cargo compartment sidewall or ceiling liner panel, including any design features, such as joints, lamp assemblies, etc., the failure of which would affect the capability of the liner…
Apparatus5.1 Heat sealer:5.1.1 Sealing Jaws—Two-heated jaws with flat sealing surfaces. Two-heated jaws are required to conduct Practice A. Practice B may be used with one-heated jaw only when the application is to commercial sealers with like configuration.5.1.1.1 Jaw Temperature Control—Each jaw must have independent temperature control. The recommended minimum precision of control is 6 1°C.5.1.1.2…
5 Physical-property requirements 5.1 Categories Physical-property requirements are organized into product categories to meet purchaser and supplier needs over a range of end-use applications. Category I Suitable for non-load-bearing applications such as wall and cavity insulation, vented roofs, cavity wall insulation and similar applications. Category II Suitable for limited load-bearing applications such as in built-up…
4 Apparatus4.1 Cold chamber, in which the test pieces are exposed to low temperature, sufficient in size to contain the bending fixture used for testing the test pieces and to permit the Operation of the fixture to bend the test piece without removal from the chamber. The cold chamber shall also have sufficient work space…
ASTM A615 Bending Requirements10.1 The bend-test specimen shall withstand being bent around a pin without cracking on the outside radius of the bent portion. The requirements for degree of bending and sizes of pins are prescribed in Table 3. When material is furnished in coils, the test specimen shall be straightened prior to placing it…
F.1 PrincipleThe test specimen is subjected to a specified number of cyclic operations whilst under lateral and longitudinal tension. F.2 ApparatusF.2.1 Vertically operated testing machine of the type shown in Figure F.1 and providing the following facilities. a) Means of holding the test specimen firmly at the bottom end, with the fastener in the closed…
F.1 GeneralThe test consists of assessing the resistance to disbondment of damage to the FJC when exposed to cathodic polarization.The test shall be performed on a test sample taken from the coated components previously subjected toholiday detection (see Annex B), and in which an artificial defect of a defined size has been drilled. The test…
