Full title and description

Steel — Ultrasonic testing of steel flat products of thickness equal to or greater than 6 mm (ISO 17577:2016). This International Standard specifies a procedure for automated and/or manual ultrasonic pulse‑echo testing to detect internal discontinuities in uncoated steel flat products in a defined nominal thickness range.

Abstract

ISO 17577:2016 defines the pulse‑echo ultrasonic method and associated acceptance considerations for detecting internal flaws in non‑alloy and alloy steel flat products (nominal thickness range 6 mm to 200 mm). The standard covers both automated and manual inspection arrangements, calibration and test conditions, applicability limits (including a note on austenitic steels) and the normal testing location (typically production or supplier premises). In disputes, the method in this International Standard is authoritative.

Scope

Specifies a pulse‑echo ultrasonic testing method (manual and/or automated) for inspection of uncoated steel flat products to detect internal discontinuities. It is primarily intended for nominal thicknesses from 6 mm up to 200 mm; application outside this range requires agreement between parties. The standard may be applied to austenitic and duplex steels only when signal‑to‑noise conditions permit, and it excludes—unless otherwise agreed—the special requirements for welded steel tubes covered by the ISO 10893‑9 series. Testing is normally performed at the producer's or supplier's premises.

Key topics and requirements

• Pulse‑echo ultrasonic testing technique for internal discontinuity detection (automated and manual modes).
• Nominal thickness applicability: typically 6 mm to 200 mm (special agreements needed outside this range).
• Scope of material: non‑alloy and alloy steels; conditional application to austenitic and austenitic‑ferritic steels when signal conditions allow.
• Calibration, equipment settings, noise/echo threshold and acceptance criteria to ensure repeatable detection performance.
• Guidance on where testing is normally carried out (production or supplier premises) and on handling disputes (the ISO method prevails).
• Reference/exception to related tube‑testing part ISO 10893‑9 for welded steel tube strip/plate testing.

Typical use and users

Used by quality engineers, NDT technicians, inspection bodies and steel manufacturers for routine production inspection and quality acceptance of steel plate and strip. It is referenced in procurement, factory inspection, supplier certification and in contractual dispute resolution where ultrasonic internal‑flaw detection is required. Users include steel mills, service centres, fabricators and third‑party NDT service providers.

Related standards

Commonly referenced alongside other nondestructive‑testing documents and tube/plate testing parts, notably ISO 10893‑9 (automated ultrasonic testing of strip/plate for welded‑tube manufacture) and standards on ultrasonic thickness measurement (e.g., ISO 16809 series). These related documents cover complementary test methods, calibration practices and applications to welded tube manufacture or thickness measurement.

FAQ

Q: What is this standard?

A: ISO 17577:2016 is an International Standard that specifies an ultrasonic pulse‑echo method (automated and/or manual) for detecting internal discontinuities in uncoated steel flat products of nominal thickness at or above 6 mm.

Q: What does it cover?

A: It covers test method, equipment and calibration considerations, acceptance-related signal/noise thresholds, applicable material types (non‑alloy and alloy steels with conditional application to some austenitic grades), and the typical thickness range of 6 mm to 200 mm. It also notes exceptions and references for welded‑tube strip/plate testing.

Q: Who typically uses it?

A: Quality managers, NDT technicians and inspection bodies in steel production, processing and fabrication environments, plus purchasers and contract inspectors who need a standardized ultrasonic method for internal‑flaw detection.

Q: Is it current or superseded?

A: ISO 17577:2016 is the 2nd edition published in January 2016 (with a corrected version in February 2016) and was reviewed/confirmed in 2021, so this edition remains current as of the latest ISO review.

Q: Is it part of a series?

A: It sits within the family of standards for nondestructive testing of steel products and is related to the ISO 10893 series (which addresses ultrasonic testing in the context of tube/strip used for welded tubes) and other NDT standards covering ultrasonic techniques and thickness measurement.

Q: What are the key keywords?

A: Ultrasonic testing, pulse‑echo, internal discontinuities, steel plate, steel strip, nondestructive testing, ISO 17577, calibration, automated inspection.
