Standards
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 part of ISO 10893 specifies requirements for automated ultrasonic testing for the detection of laminar imperfections
a) in the pipe body (full peripheral testing) of seamless and welded, except submerged arc-welded (SAW),
steel tubes, or
b) in the area adjacent to the weld seam of welded steel tubes, and optionally
c) at the ends (full peripheral testing) of seamless and welded tubes.
This part of ISO 10893 can also be applicable to the testing of circular hollow sections.
NOTE For welded tubes, see ISO 10893-9 for an alternative test method for the detection of laminar imperfections in steel strip/plate prior to tube forming.
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 document defines welding positions for testing and production, for butt and fillet welds, in all product forms.
Annex A gives examples of the limits of the slope of a weld axis and the rotation of the weld face about the weld axis for welding positions in production welds.
Annex B gives a comparison of this document and US designation systems for welding positions.
This standard specifies the quality requirements of tomatoes of varieties (cultivars) grown from Lycopersicum esculentum Mill., which are to be supplied fresh to the consumer after reparation and packaging. The standard does not apply to tomatoes for industrial processing. Tomatoes covered under this standard may be classified into four commercial types: a) “round”; b) “ribbed”; c) “oblong” or “elongated”; and d) “cherry” tomatoes (including “cocktail” tomatoes).
This International Standard specifies the characteristics of materials for resistance welding electrodes and ancillary equipment which are used for carrying current and transmitting force to the work.
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 International Standard specifies requirements for classification of nonconsumable tungsten electrodes for inert gas shielded arc welding, and for plasma welding, cutting and thermal spraying. Information on conditions of use of these electrodes is given in Annex A (informative).
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.
