This document specifies the requirements for automatic ultrasonic detection of laminar imperfection in steel strips/plates used for the manufacture of welded steel tubes before or during the tube making process. NOTE 1: For welded steel tubes, at the option of the manufacturer, automated ultrasonic testing of the steel tube for laminar imperfection according to ISO 10893-8 after welding is an alternative method. NOTE 2: Upon agreement between the manufacturer and the purchaser, this document is also applicable to the inspection of steel strips/plates after welding of submerged arc welded steel tubes. This document also applies to the inspection of steel strips/plates used in the manufacture of circular hollow steel profiles.

This document specifies the requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes for surface imperfections on the tube body and imperfections on the end face/bevel at the tube ends. This document specifies the requirements for the detection of imperfections on the outer surface of all or part of steel tubes. Upon negotiation and agreement between the purchaser and the manufacturer, it can be applied to the detection of the inner surface over a limited length from the tube end (depending on the diameter of the steel tube). When applicable, this document can be used to locate the position of the external surface imperfections detected by other non-destructive testing (such as ultrasonic) methods before grinding, and to confirm that the imperfections have been completely removed after grinding. This document specifies the requirements for the detection of laminar imperfections on the end face/bevel at both ends of plain-end tubes and beveled-end tubes that may affect subsequent manufacturing and testing (such as welding and ultrasonic testing of welds). This document applies to the detection of laminar imperfections and other imperfections on the end face/bevel. In this case, the direction of the magnetic field shall be as perpendicular to the direction of the imperfection being detected as possible. This document also applies to the inspection of hollow parts.

This document describes a method for the determination of explosion limits of the combustible mixture of combustible gases (vapors) and air at a given initial temperature and initial pressure. This document applies to the determination of explosion limits of combustible gases (vapors) under the conditions of initial temperature below 200 ¡ãC, initial pressure below 1.0 MPa (absolute pressure), and maximum explosion pressure not greater than 15.0 MPa (absolute pressure). This document does not apply to the determination of explosion limits of chemically unstable gases or mixed gases in which components may react with each other.

This document specifies the requirements for automated ultrasonic transverse wave (generated by conventional or phased array technology) inspection of submerged arc welded (SAW) steel tube or resistance and induction welded (EW) steel tube welds. For SAW tube, this inspection includes detection of imperfections primarily parallel to the weld, or perpendicular to the weld according to agreement, or in both directions. For EW steel tubes, this inspection includes the detection of imperfections oriented mainly parallel to the weld. For longitudinal imperfections, Lamb wave detection is chosen by the manufacturer. For imperfections in the EW tube welds, full circumferential ultrasonic inspection can be performed. This document also applies to the inspection of circular hollow profiles. NOTE: For full circumferential ultrasonic testing of seamless steel tubes and welded steel tubes (except SAW steel tubes), see ISO 10893-10.
