Standards

This document specifies quality levels of imperfections in fusion-welded joints (except for beam welding) in all types of steel, nickel, titanium and their alloys. It applies to material thickness ≥ 0,5 mm.  It covers fully penetrated butt welds and all fillet welds. Its principles can also be applied to partial penetration

butt welds. Quality levels for beam-welded joints in steel are presented in ISO 13919-1.

Three quality levels are given in order to permit application to a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld.  Several types of loads are considered, e.g. static load, thermal load, corrosion load, pressure load.

Additional guidance on fatigue loads is given in Annex B. The quality levels refer to production and good workmanship.

This document is applicable to:

a) non-alloy and alloy steels;

b) nickel and nickel alloys;

c) titanium and titanium alloys;

d) manual, mechanized and automatic welding;

e) all welding positions;

f) all types of welds, e.g. butt welds, fillet welds and branch connections;

g) the following welding processes and their sub-processes, as defined in ISO 4063:

— 11 metal arc welding without gas protection;

— 12 submerged arc welding;

— 13 gas-shielded metal arc welding;

— 14 gas-shielded arc welding with non-consumable tungsten electrode;

— 15 plasma arc welding;

— 31 oxyfuel gas welding (for steel only).

Metallurgical aspects, such as grain size and hardness, are not covered by this document.

This specifies designations for filler materials for soft soldering, brazing and braze welding, on the basis of their chemical composition. For brazing and braze welding materials only, the designation includes their solidus /liquidus temperatures.  It deals only with those filler metals used in soft soldering, brazing and braze welding which do not incorporate flux, either as a covering or as an integral part of the filler material.

This document specifies designations for filler materials for brazing on the basis of their chemical composition. The designation includes their solidus/liquidus temperatures. This document applies to the metallic part of filler materials used in brazing products, for example foils, wires, rods, pastes, flux-coated rods or wires and flux-cored rods or wires.

This standard specifies a test method for determining the acceptance limits of surface discontinuities detected by liquid penetrant inspection, when such an inspection procedure has been contractually agreed upon at the request of the purchaser. It applies to all steel castings; whatever casting process is used.

This standard specifies the testing conditions and the acceptance standard for ultrasonic acceptance tests for the components and types of test covered in table 1, columns 1 to 6.  Unless otherwise agreed, this standard shall be applied when the product standards require mandatory ultrasonic tests or when the ordered optional tests are made mandatory (See ISO 1005-1, ISO 1005-3 and ISO 1005-6) ISO 1005-6, specifies ultrasonic acceptance tests are mandatory for all wheels of testing category B, but optional for all wheels of testing category A. According to ISO 1005-1 and ISO 1005-3, ultrasonic acceptance tests on tyres and axles are optional in every case.

This standard specifies general rules for appropriate implementation of radiographic inspection and stresses the technical specifications to be defined for agreement on discontinuity acceptance criteria by this technique. It applies to aluminum castings.

 This standard specifies a method for liquid penetrant inspection of discontinuities rising to the surface of aluminium alloy and magnesium alloy products and castings. It also defines severity levels as a function of the nature and number of discontinuities present. This standard applies to all aluminium alloy and magnesium alloy castings, whatever their grade and the casting procedure used to produce them.

This standard specifies a visual method for assessing the porosity of the machined surface of aluminium alloy castings. This method cannot be used for assessing porosity present on radiograms.

 This standard specifies the requirements, method of rating and testing of single-, two-, three-, and four-branch chain slings assembled by methods other than welding, using grade T (8) chain conforming to ISO 1834 and ISO 3076, together with the appropriate range of components.  This standard does not apply to chain slings assembled by welding (see ISO 4778), to slings designed to have branches of unequal nominal reach, to endless slings, or to slings designed for special applications.

This standard specifies requirements for the operation of laboratories and is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing activities.

This standard is for use by laboratories in developing their quality, administrative and technical systems that govern their operations. Any party may use this standard when confirming or recognising the competence of laboratories.
