Standards

This standard describes the qualification and certification of personnel engaged in non-destructive testing (NDT) of seamless and welded steel tubes, including flat products used in the manufacture of welded tubes, for pressure purposes. It specifies the training, qualification and certification requirements for three levels of NDT personnel competence to execute specific tasks in the NDT of seamless and welded steel tubes, including the weld seam, and flat products used in the manufacture of welded tubes.

This standard specifies requirements for full peripheral ultrasonic testing of the ends of seamless and welded tubes for the detection of laminar imperfections. It is intended to detect, over a zone at the ends of plain end and bevelled end tubes, laminar imperfections which may interfere with subsequent fabrication operations (e.g.) welding, ultrasonic inspection of welds, etc). This standard is applicable to the inspection of tubes with an outside diameter greater than 30 mm. No lower limit of thickness is specified, but see note 1.

This standard defines working positions and makes it possible to locate welds in space with reference to the horizontal reference plane (usually parallel to the workshop floor) by means of angles of slope and rotation which are independent from surrounding construction. 

This second edition cancels and replaces the first edition (ISO 5182:1978). Specifies the characteristics of the materials which are used for carrying current and transmitting force to the work. Gives normative references. Defines the term softening temperature. Classifies copper and copper alloys and sintered materials. Specifies test methods, designation, typical applications (annex A), hardness conversions (annex B). Annexes C and D contain properties and bibliography, respectively.

This standard lays down requirements for tungsten electrodes for inert gas shielded arc welding, and for plasma cutting and welding.  

 This standard lays down the general specifications, requirements and tests of safety devices for fuel gases and oxygen or compressed air used downstream of cylinder or pipeline outlet regulators and of pipeline outlet valves, and upstream of blowpipes for welding, cutting and allied processes. It does not specify location and combination of these devices in the gas system.  

  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. 

  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 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.
