Standards

 This standard lays down general requirements on penetrant flaw detectors and their functional units which are designed to reveal invisible, or poorly visible to the eye, surface discontinuities in metals and non-metals of any geometry and at any stage of manufacture.

 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.

 This standard specifies a test method for determining the acceptance limits of surface discontinuities detected by magnetic particle inspection, when such an inspection procedure has been contractually agreed upon at the request of the purchaser.  It applies to all magnetic steel castings; whatever casting process is used.  A steel shall be considered to be magnetic if the magnetic induction is greater than 1 T for a magnetic field

strength equal to 2, 4 KA/m.

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.

 For the interpretation of radiographs and the assignment of radiographic quality levels to a casting, it is necessary to use a standard set of reference radiographs. The reference radiographs available from ASTM (see clause 2) are the only internationally used and recognized documents that may be used for this purpose.

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.
