Standards

  This standard specifies requirements for taper plug and ring gauges used for the checking of type A, B and C tapers according to ISO 1089. 

 This standard specifies the dimensions and tolerances of resistance spot welding electrode adaptors where the fixing element for the cap is a female taper (male electrode cap, see ISO 5830) and for which the electrode taper fits conform to ISO 1089.  

  This standard covers graphical symbols which are placed on resistance welding equipment, e.g., indicators and operator's controls, in order to instruct the persons handling the equipment as to its use and operation. 

The standard specifies dimensions and requirements for insulated caps and bushes in the secondary circuit for resistance welding equipment, especially for use in back-ups according to ISO 5827.  

  This standard specifies the maximum external leakage rates, which are acceptable for equipment used for welding, cutting and allied processes.  It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant).  It does not apply to gas supply plants. 

This document specifies the maximum external gas leakage rates which are acceptable for equipment used for welding, cutting and allied processes and provides the procedures of measurement.

It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant). It does not apply to gas supply plant.

NOTE Specific requirements on the test method and conditions/procedure for measurement of the maximum external leakages can be given in individual standards, e.g. ISO 9012 for air-aspirated hand blowpipes. Concerning the method and the conditions to be applied, the individual standard takes precedence over this document. The maximum external leakages according to this document apply. 

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.
