BS EN 12814‑8 is one of a multi-series standard that provides the requirements for tests on welded thermoplastics semi-finished products.
BS EN 12814‑8 provides guidelines on selecting of the appropriate test methods in accordance with the particular type and application of the welded product.
The test results depend on the conditions of manufacture for the test specimen and on the test conditions. They can therefore only be related to the behaviour of the product or can only be used for designing a structure if the test conditions can be related to the service conditions.
BS EN 12814‑8 on welded joints of thermoplastics is applicable to:
Sometimes the life of a product is significantly shorter simply because of poor weld quality. Testing and visual inspection of thermoplastic welding are important to identify and ensure the quality of these welded joints. BS EN 12814-2 provides you with guidelines for test requirements for welded thermoplastic products. The selection of appropriate test methods would be in accordance with the type and application of the welded product.
Tensile tests include tensile creep tests, peel tests, low temperature tensile tests, and macroscopic examination. Following BS EN 12814-2 also provides you with the dimensions and methods for sampling. BS EN 12814-2 guides you in preparing test specimens for these products.
BS EN 12814‑8:2021 supersedes BS EN 12814‑8:2001, which is withdrawn. BS EN 12814‑8:2021 includes some technical changes with respect to BS EN 12814‑8:2021. These include:
