GOST 24507-80 PDF

Full title and description

GOST 24507-80 — Non-destructive testing. Forgings from ferrous and non-ferrous metals. Ultrasonic methods of flaw detection. The standard (original Russian title: "Контроль неразрушающий. Поковки из чёрных и цветных металлов. Методы ультразвуковой дефектоскопии") specifies ultrasonic procedures and general requirements for detecting internal discontinuities in forgings.

Abstract

This standard applies to forgings of ferrous and non‑ferrous metals with a nominal thickness of 10 mm or more and establishes ultrasonic methods intended to detect defects such as cavities (blowholes), laps, cracks, flakes, delaminations and non‑metallic inclusions (without necessarily determining their precise nature or exact size). It sets the scope of testing, typical techniques and references to general ultrasonic testing requirements.

General information

• Status: In force / active (standard retained and used in national libraries and technical collections).
• Publication date: Introduced 1 January 1982 (designation year 1980 — suffix "-80").
• Publisher: Approved by the USSR State Committee for Standards (Gosstandart / Interstate standard); later maintained in national/regional collections.
• ICS / categories: Non‑destructive testing of metals — ICS 77.040.20 (OKS/ОКС references also used in cataloguing).
• Edition / version: Original designation GOST 24507-80; includes Change No. 1 (IUS 8‑86) as recorded in amendments.
• Number of pages: Typically published as a short standard (about 12–14 pages depending on edition/translation).

Scope

GOST 24507-80 covers ultrasonic defectoscopy methods applied to forged parts (forgings) made of both ferrous and non‑ferrous metals where thickness is 10 mm or greater. The standard defines which types of discontinuities the ultrasonic methods are intended to reveal, identifies measurement and scanning practices required to locate and characterise indications qualitatively, and refers to technical documentation for limits of acceptability and required testing volumes. It is intended for production and incoming inspection of forgings but does not itself replace product‑specific acceptance criteria, which are set in contractual or technical documents.

Key topics and requirements

• Scope and applicability for forgings of thickness ≥ 10 mm.
• Types of detectable defects (cavities/blowholes, laps, cracks, flakes, delaminations, non‑metallic inclusions) and limitations (no absolute sizing or material‑type identification claimed).
• Recommended ultrasonic inspection methods and general procedural requirements (probe selection, coupling, scanning directions and acceptance of pulse‑echo techniques consistent with general ultrasonic standards).
• Calibration and sensitivity checks tied to standard test blocks and reference levels (as referenced to general ultrasonic testing rules).
• Requirements to record test results and to reference technical documentation for acceptance levels and sampling/testing extent.

Typical use and users

Typical users are quality engineers, non‑destructive testing (NDT) technicians and inspection laboratories working in forging plants, foundries, metalworking shops, heavy engineering and equipment manufacturers, and procurement/QA departments that require acceptance testing of forgings. The standard is used for production control, incoming inspection of supplied forgings, and as a normative reference when establishing factory inspection procedures and acceptance criteria in technical specifications.

Related standards

GOST 24507-80 is used alongside broader and related NDT standards, for example general ultrasonic testing requirements (GOST 20415-82) and other forging and metal testing standards (for example GOST 21120-75, GOST 22727-88). It also corresponds in subject matter to parts of international documents on ultrasonic testing of metal products (see ICS grouping 77.040.20).

FAQ

Q: What is this standard?

A: GOST 24507-80 is a Soviet / interstate standard specifying ultrasonic non‑destructive testing methods for forgings made of ferrous and non‑ferrous metals.

Q: What does it cover?

A: It defines the application of ultrasonic methods to detect internal defects (cavities, laps, cracks, flakes, delaminations, non‑metallic inclusions) in forgings of thickness 10 mm and above, and provides procedural and calibration guidance while delegating acceptance limits to product technical documentation.

Q: Who typically uses it?

A: NDT technicians, quality/control engineers, inspection laboratories, forging manufacturers and procurement/QA specialists involved in production or acceptance of forgings. They use it to develop inspection procedures, training, and to define test coverage for forgings.

Q: Is it current or superseded?

A: Public technical libraries and national catalogues list GOST 24507-80 as in force/active; some countries/organizations continue to use it alongside newer national or international ultrasonic testing standards. Users should verify whether product‑specific regulations or more recent national/international standards have been adopted for their jurisdiction or application.

Q: Is it part of a series?

A: It is one of a set of normative documents addressing ultrasonic and other non‑destructive testing methods for metal products (related GOSTs cover general ultrasonic testing requirements and specific product forms such as bars, plates and welded joints). See related GOST references for the broader NDT framework.

Q: What are the key keywords?

A: Ultrasonic defectoscopy, forgings, non‑destructive testing, internal discontinuities, calibration, acceptance criteria, GOST 24507-80.
