. This part of GYS 120 specifies a non-destructive penetrant testing for determining bond defects and discontinuities in the sliding surface of the bearing. The penetration method is used to detect - bond defects in the transitional area between the bearing backing/bearing material on the end faces and joint faces of multilayer plain bearings which cannot be detected by the ultrasonic testing method specified in ISO 4386- 1; discontinuities in the sliding surface of the bearing. The penetration method is applicable, in principle, to finished multilayer plain bearings.

This standard specifies requirements for full peripheral ultrasonic shear wave testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of longitudinal imperfections according to four different acceptance levels (see table 1). This standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 9 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5. For tubes with an outside diameter-to-thickness ratio less than 5, one of the methods specified in Annex A shall be used by agreement between manufacturer and purchaser. 

  This standard specifies requirements for eddy current testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections, according to two different acceptance levels (see tables 1 and 2).  It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm. 

  This standard specifies requirements for the ultrasonic testing of the weld seam of electric resistance and induction welded steel tubes for the detection of predominantly radial longitudinal imperfections, according to two different acceptance levels.

This standard specifies requirements for the ultrasonic testing of the weld seam of submerged arc-welded (longitudinally or spirally) tubes for the detection of imperfections oriented predominantly parallel to and/or at right angles to the weld seam, according to three different acceptance levels (see table 1 and table 2).  This standard covers the inspection of tubular products with outside diameter greater than or equal to 150 mm. 

This standard specifies requirements for ultrasonic thickness testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for verification of hydraulic leak-tightness.

This standard specifies requirements for full peripheral ultrasonic thickness testing of seamless and hot-stretch-reduced welded steel tubes.

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 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.
