examination of welds in thermoplastic materials It may also be applied to visual testing of the joint prior to and during the welding Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application For dated references, only the edition cited applies For undated re ferences, the latest edition o f the re ferenced document (including any amendments) applies EN 14728, Imperfections in thermoplastic welds — Classification EN 16296, Imperfections in thermoplastics welded joints — Quality levels EN ISO 17637:2016, Non-destructive testing of welds — Visual testing of fusion-welded joints (ISO 17637:2016) EN ISO 17659, Welding — Multilingual terms for welded joints with illustrations (ISO 17659) Test conditions and equipment The illuminance at the surface, shall be a minimum of 350 lx, 500 lx is recommended For direct visual examination o f welds, access shall be su fficient to allow the eye to be placed within a distance of 600 mm from the weld, around the whole weld and the viewing angle shall not be less than 30° Remote visual examination o f welds using mirrors, boroscopes, fibre optics or cameras shall be considered as additional requirements and shall be specified by an application standard or by agreement between the contracting parties If a good contrast and relief effect between imperfections and background is required, an additional light source can be used The equipment (e.g.: gauges, callipers) used for the dimensional check o f the weld shall ensure the necessary precision level, in accordance with the applicable acceptance criteria Examples of examination equipment are given in EN ISO 17637:2016, Annex A Personnel Visual examination o f welds and the evaluation o f results for final acceptance should be per formed by personnel qualified and familiar with the relevant standards, rules, specifications and the welding procedure [1] used It is recommended that personnel should be qualified in accordance with EN ISO 9712 or an equivalent standard at an appropriate level in the relevant industry sector Visual examination 5.1 General The examination is normally performed on welds in the as‑welded condition; however, for example when required by an application standard or by agreement between the contracting parties, the examination may be also carried out at other stages during the welding process, such as for checking the weld preparation and during the welding, for evaluating the effective application of the relevant welding procedure specification [1] BS EN 13100‑1:2017 EN 13100‑1:2017 (E) The extent o f examination and the acceptance criteria o f the imper fections shall be defined in advance by EN 16296, an application standard or by agreement between the contracting parties The examiner shall have access to the necessary inspection and production documentation required The classification o f the imper fections can be found in EN 1472 The terms to be used are available in EN ISO 17659 5.2 Visual examination of joint preparation When visual examination is required prior to welding, the joint preparation shall be examined to check that the shape, dimensions and the cleaning conditions of the weld preparation meet the specified requirements given in the relevant standards and/or in the applicable welding procedure specification [1] During this examination special attention should be paid to the correct fixing o f the parts to be welded (e.g.: linear and angular alignment, gap) 5.3 Visual examination during welding When required, in the case of multipass welding processes, the weld shall be examined during the welding process to check that: a) each run is cleaned and/or scraped be fore it is covered by subsequent runs; b) there are no visible imper fections (such as cracks or cavities) , i f imper fections are observed, they shall be reported immediately so that remedial action can be taken before the execution of the next run; c) the transition between the runs and between the weld and the parent material is so formed that d) a fter any necessary repairs/remedial action, the weld forms to the original requirements o f the welding procedure specification 5.4 satisfactory penetration can be accomplished when welding the next run; Visual examination o f the finished weld Welds shall be examined in the as‑welded condition and shall also be examined after any surface treatment (i f any) The finished weld shall be examined to determine whether it meets the requirements o f the application or product standard or other agreed acceptance criteria, on the basis o f specific quality levels as defined in EN 16296 All the imperfections that are not permissible shall be reported 5.5 Visual examination of repaired welds When a weld fails to comply wholly or in part with the applicable acceptance criteria and repair is necessary, the repaired weld shall be re‑examined to the same requirements as the original weld Test report When test records are required, at least the following information shall be included in the report: a) name o f the component manu facturer; b) name o f the examining body, i f di fferent from the component manu facturer; BS EN 13100‑1:2017 EN 13100‑1:2017 (E) c) re ference to this standard; d) location o f the weld(s); e) the applicable acceptance criteria; f) type o f material(s); g) material thickness; h) type o f j oint; i) welding process; j) extent o f examination; k) examination devices used (i f any); l) result o f examination, with the detail o f the imper fections exceeding the acceptance criteria and their location; m) name and signature o f examiner and date o f examination If a permanent visual record of an examined weld is required, photographs or accurate sketches or both shall be made with any imperfections clearly indicated BS EN 13100‑1:2017 EN 13100‑1:2017 (E) Bibliography [1] [2] CEN/TS 16892,
