GOST 20415-82 PDF

Full title and description

GOST 20415-82 — "Контроль неразрушающий. Методы акустические. Общие положения" / "Non‑destructive testing. Acoustic methods. General principles". The standard establishes general provisions for the use of acoustic (acoustical) nondestructive testing methods, requirements for technical documentation, and training/qualification of personnel performing acoustic NDT.

Abstract

GOST 20415-82 defines conditions and procedures for applying acoustic nondestructive testing methods at enterprises, the required structure and content of technical (inspection) documentation, equipment and sample requirements, safety provisions, and training and certification rules for NDT personnel (radiographers/defectoscopists) working with acoustic methods. It is a national (interstate) normative document first introduced in 1983 to replace the 1975 edition.

• Number of pages: Typically short technical standard — published editions list approximately 4 pages (concise general provisions document).

Scope

This standard applies to enterprise-level organisation of acoustic methods of nondestructive testing. It covers when and how acoustic methods should be applied for product and component control, the mandatory contents and structure of inspection technical documentation, requirements for equipment, reference samples and metrological support, safety requirements during acoustic testing, and the training, examination and periodic re‑qualification of personnel who perform acoustic NDT. It is intended to be referenced by industry technical documents and by enterprises that implement acoustic NDT programs.

Key topics and requirements

• Conditions and grounds for using acoustic NDT methods (selection criteria, confirmation of accuracy and reliability for the test object).
• Required structure of control documentation: scope, object descriptions, list of detectable defects, allowable sizes/limits, and reference to governing technical documents.
• Equipment and instrumentation requirements: types/brands of equipment, transducers/converters, calibration/test samples, tuning procedures, and metrological support.
• Specification of sample (standard) specimens and instructions for non‑standard accessories or test specimens.
• Rules for registration and presentation of inspection results, defect classification, acceptance criteria and reporting forms.
• Safety and operational requirements for performing acoustic tests (equipment operation, environmental and personnel safety guidance).
• Training, examination and certification requirements for acoustic NDT personnel, plus rules for periodic re‑qualification and loss-of-qualification after extended absence.

Typical use and users

Primary users include NDT engineers and technicians (defectoscopists/radiographers) working in metallurgy, mechanical engineering, aerospace, oil & gas, power generation, transport and repair/maintenance facilities. Quality assurance departments, certification bodies and technical standards writers also use this standard to define enterprise procedures, documentation and personnel qualification for acoustic testing.

Related standards

Normative references and close documents include the national classification of NDT methods (GOST 18353-79) and other GOST documents on specific NDT techniques and procedures. GOST 20415-82 formally replaces GOST 20415-75; other sectoral or method-specific GOSTs and GOST‑R/ISO equivalents covering ultrasonic, acoustic emission and related practices are commonly used alongside it.
