It may also be applied to visual testing of the joint prior to and during the welding.2 Normative referencesThe following documents, in whole or in part,

18、are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.EN 14728, Imperfections in thermoplastic welds Classif

20、mentThe illuminance at the surface, shall be a minimum of 350 lx, 500 lx is recommended.For direct visual examination of welds, access shall be sufficient 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.Re

21、mote visual examination of 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 backgrou

22、nd is required, an additional light source can be used.The equipment (e.g.: gauges, callipers) used for the dimensional check of 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

23、, Annex A.4 PersonnelVisual examination of welds and the evaluation of results for final acceptance should be performed 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 acco

24、rdance with EN ISO 9712 or an equivalent standard at an appropriate level in the relevant industry sector.5 Visual examination5.1 GeneralThe examination is normally performed on welds in the aswelded condition; however, for example when required by an application standard or by agreement between the

25、 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 1.4 BS EN 131001:2017EN 131001:2017 (E)

26、The extent of examination and the acceptance criteria of the imperfections 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 classificat

27、ion of the imperfections can be found in EN 14728.The terms to be used are available in EN ISO 17659.5.2 Visual examination of joint preparationWhen visual examination is required prior to welding, the joint preparation shall be examined to check that the shape, dimensions and the cleaning condition

28、s 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 of the parts to be welded (e.g.: linear and angular alignment, gap).5.3

29、Visual examination during weldingWhen 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 before it is covered by subsequent runs;b) there are no visible imperfections (such as cracks or cavit

30、ies), if imperfections 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 satisfactory penetration can be accomplished when weldin

31、g the next run;d) after any necessary repairs/remedial action, the weld conforms to the original requirements of the welding procedure specification.5.4 Visual examination of the finished weldWelds shall be examined in the aswelded condition and shall also be examined after any surface treatment (if

32、 any).The finished weld shall be examined to determine whether it meets the requirements of the application or product standard or other agreed acceptance criteria, on the basis of specific quality levels as defined in EN 16296.All the imperfections that are not permissible shall be reported.5.5 Vis

33、ual examination of repaired weldsWhen a weld fails to comply wholly or in part with the applicable acceptance criteria and repair is necessary, the repaired weld shall be reexamined to the same requirements as the original weld.6 Test reportWhen test records are required, at least the following info

34、rmation shall be included in the report:a) name of the component manufacturer;b) name of the examining body, if different from the component manufacturer;5BS EN 131001:2017EN 131001:2017 (E)c) reference to this standard;d) location of the weld(s);e) the applicable acceptance criteria;f) type of mate

35、rial(s);g) material thickness;h) type of joint;i) welding process;j) extent of examination;k) examination devices used (if any);l) result of examination, with the detail of the imperfections exceeding the acceptance criteria and their location;m) name and signature of examiner and date of examinatio

36、n.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.6 BS EN 131001:2017EN 131001:2017 (E)Bibliography1 CEN/TS 16892, Plastics Welding of thermoplastics Specification of welding procedures2 EN
