Doplňujúce informácie
| 1. Scope | ||||||||
|
1.1 This practice covers the preparation and evaluation of joints between two pieces of weldable grades of thermoplastic materials, backed and unbacked, (such as those shown in Table 1) up to 2 in. (50 mm) in thickness. 1.2 Since there are numerous new technologies and techniques constantly being developed for plastic welding, there are no profiles and procedures that can be considered as standard for all plastics at various thicknesses. This practice is not intended to define profiles and procedures; however, it is intended to establish methods to evaluate minimum short term weld factors to be achieved by the welder for the respective plastics. 1.3 Weld procedures used for test pieces should reflect procedures to be used in actual fabrication. 1.4 Welding methods to be used could include machine welding, extrusion welding, and hot gas welding. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. |
