Full title and description

ISO 10543:1993 — Seamless and hot-stretch-reduced welded steel tubes for pressure purposes — Full peripheral ultrasonic thickness testing. Specifies requirements for the method of test, equipment calibration and checking, acceptance and test reporting for full-peripheral ultrasonic thickness measurement of tubes.

Abstract

Specifies general requirements and specific requirements with regard to the method of test, reference standards, equipment calibration and checking, acceptance criteria and the required information in the test report for full peripheral ultrasonic thickness testing of seamless and hot-stretch-reduced welded steel tubes for pressure purposes.

General information

• Status: Withdrawn.
• Publication date: 18 November 1993 (published 1993-11).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 23.040.10; 77.040.20; 77.140.75 (iron & steel pipes; non‑destructive testing of metals; steel pipes and tubes for specific use).

Scope

ISO 10543:1993 covers the full peripheral ultrasonic thickness testing of seamless and hot-stretch-reduced welded steel tubes intended for pressure purposes. It defines the test method, required reference standards, calibration and checking procedures for equipment, acceptance criteria and the content of the test report. The standard is limited to thickness measurement by full‑peripheral ultrasonic techniques as applied to these tube types.

Key topics and requirements

• Applicability to seamless and hot-stretch-reduced welded steel tubes used for pressure purposes.
• Definition of the full peripheral ultrasonic thickness testing method and scanning approach.
• Requirements for reference standards and calibration procedures for ultrasonic equipment.
• Procedures for checking equipment performance and calibration verification.
• Acceptance criteria for measured wall thickness and requirements for the test report (documentation content).
• Note on replacement: the content and practical application were later incorporated into the ISO 10893 series (see ISO 10893‑12:2011 which revises and extends the topic for automated full peripheral ultrasonic thickness testing).

Typical use and users

This standard was used by tube manufacturers, quality and inspection departments, non‑destructive testing (NDT) laboratories, third‑party inspection bodies, pressure‑equipment manufacturers and design/engineering teams responsible for specifying and verifying wall thickness of seamless and welded pressure tubes. National standards bodies and conformity assessment organizations refer to it when establishing inspection procedures.

Related standards

ISO 10543:1993 has been withdrawn and its subject matter was consolidated into the ISO 10893 series. It is specifically revised by ISO 10893‑12:2011 (Automated full peripheral ultrasonic thickness testing) and later amended (ISO 10893‑12:2011/Amd 1:2020). Related parts of the ISO 10893 series (for example ISO 10893‑8 on laminar imperfections) are relevant when combined inspections are performed.

FAQ

Q: What is this standard?

A: ISO 10543:1993 is an International Standard that specified requirements for full peripheral ultrasonic thickness testing of seamless and hot‑stretch‑reduced welded steel tubes for pressure purposes. It described test methods, calibration, acceptance criteria and reporting.

Q: What does it cover?

A: It covers the method and procedural requirements for ultrasonic wall‑thickness measurement performed over the full periphery of tubes (test method, reference standards, equipment calibration/checking, acceptance and test reporting).

Q: Who typically uses it?

A: Tube manufacturers, NDT laboratories, inspection and quality control personnel, third‑party inspectors, and engineers responsible for pressure‑tube specification and verification. Standards bodies and conformity assessment organizations also used it as a reference.

Q: Is it current or superseded?

A: ISO 10543:1993 has been withdrawn (withdrawal recorded 24 March 2011) and its subject matter is now covered by ISO 10893‑12:2011 (with a subsequent amendment in 2020). For current requirements and updated acceptance criteria you should refer to ISO 10893‑12:2011 and its amendment.

Q: Is it part of a series?

A: Yes — the topic belongs to the broader ISO 10893 series (Non‑destructive testing of steel tubes). ISO 10893‑12:2011 is the modern part addressing automated full peripheral ultrasonic thickness testing and links to other parts of the series for detection of lamination and other NDT topics.

Q: What are the key keywords?

A: full peripheral ultrasonic thickness testing; ultrasonic; non‑destructive testing; wall thickness; seamless tubes; welded tubes; pressure purposes; calibration; acceptance criteria; ISO 10543 / ISO 10893.
