GOST 27451-87 PDF

Full title and description

GOST 27451-87 — "Ionizing radiation measuring means. General specifications". This standard establishes general technical requirements, metrological characteristics, testing, marking, documentation, packaging and storage rules for instruments and devices used to measure ionizing radiation (dosimetric and radiometric measuring means).

Abstract

GOST 27451-87 provides a unified set of technical conditions for a wide range of instruments for detection and measurement of ionizing radiation (gamma, X, beta, alpha, neutron where applicable). It sets out definitions, required metrological and environmental characteristics, reliability and safety requirements, rules for acceptance testing, calibration/verification intervals, documentation, marking, packaging and storage. The standard is referenced by other GOSTs and aligned in part with multiple IEC standards for radiation-protection instrumentation.

General information

• Publication date: Introduced (approved) by the State Committee for Standards of the USSR on 23 October 1987; brought into effect 01 January 1989.
• Publisher: State Committee for Standards of the USSR (Gosstandart) — Госстандарт СССР.
• ICS / categories: Radiation protection and radiation measurements — commonly associated ICS sectors for this subject area include 13.280 (Radiation protection instrumentation) and 17.240 (Radiation measurements).
• Edition / version: Designation GOST 27451-87 (approved 1987). Contains recorded amendments (examples cited in commercial records: amendments from 1989 and 1995).
• Number of pages: 55 pages (typical print/pdf editions list 55 pages).

Scope

Applies to measuring instruments and measurement systems intended for detection, monitoring and quantification of ionizing radiation (including dosimeters, radiometers, survey meters, contamination monitors and associated measuring assemblies). The standard covers general technical and metrological requirements, testing procedures, environmental and mechanical endurance criteria, verification/calibration intervals and documentation necessary to ensure reliable, reproducible and safe operation of radiation measuring means. It is intended to be used alongside more specific standards for particular instrument types and test methods.

Key topics and requirements

• Definitions and classification of radiation measuring means (dosimetric and radiometric categories).
• Metrological characteristics and permissible measurement errors (accuracy, sensitivity, energy and angular dependence, range).
• Environmental, climatic and mechanical requirements (temperature, humidity, vibration, shock, ingress protection and EMC considerations where relevant).
• Reliability, lifetime and maintenance requirements; intervals and procedures for verification and calibration (periodicity defined in the standard and by regulatory practice).
• Safety and protection requirements for instruments used in ionizing radiation fields.
• Acceptance and type-testing procedures, including reference conditions and test methods.
• Documentation, marking, labeling, packaging, transportation and storage requirements.
• Normative references and alignment with relevant international (IEC) and regional standards for radiation-protection instrumentation.

Typical use and users

Manufacturers and designers of radiation detection and dosimetry equipment; calibration and testing laboratories; regulatory and certification bodies; radiation protection officers and health physics personnel in industrial, medical, research and nuclear facilities; procurement and quality assurance teams specifying instrument requirements. The standard is used as a base document when developing or approving type specifications and for ensuring metrological traceability and operational safety.

Related standards

GOST 27451-87 cross-references and aligns with a range of IEC radiation-protection standards and other GOSTs. The standard text notes correspondence with multiple IEC standards (examples listed in the official record include IEC publications referenced as numbers 325, 395, 421, 460, 468, 504, 532, 579, 761, 861 and 323 in the original informational data). Related national standards frequently cited alongside GOST 27451-87 include instrument-specific GOSTs such as GOST 26652-85 (scintillation detection units — test requirements) and others dealing with radiometric instruments and measurement methods.

FAQ

Q: What is this standard?

A: GOST 27451-87 is the Soviet/Russian national standard that defines general technical specifications and requirements for instruments used to measure ionizing radiation (dosimetric and radiometric measuring means).

Q: What does it cover?

A: It covers definitions, classification, metrological characteristics, environmental and mechanical requirements, reliability and maintenance, calibration/verification periodicity, acceptance testing, documentation, marking, packaging and storage rules for radiation measuring instruments.

Q: Who typically uses it?

A: Equipment manufacturers, test and calibration laboratories, certification and regulatory authorities, radiation safety officers and procurement or QA teams working with radiation-detection and dosimetry equipment.

Q: Is it current or superseded?

A: Records in standards catalogues and libraries indicate GOST 27451-87 was approved in 1987 and entered into force on 01 January 1989, with recorded amendments in later years; several databases list it as active (действующий) but users should verify national/regional applicability and any later replacements or superseding intergovernmental standards for specific instrument classes. For official regulatory use always confirm the current status with the appropriate national standards body or an authoritative standards database.

Q: Is it part of a series?

A: GOST 27451-87 is a general/umbrella technical specification intended to be used together with more specific GOSTs and type-specific standards for particular instrument families (scintillation units, radiometers, personal dosimeters, etc.) and with international IEC standards on radiation-protection instrumentation.

Q: What are the key keywords?
