Описание (английский):

IEC 62598:2011 applies to the manufacture and installation of electrical measuring systems and instruments utilizing radioactive sources (radiometric gauges, hereinafter called gauges). It also applies to source housings intended for use in the aforementioned measuring systems. This standard applies to equipment, which is not related to power production or to the fuel cycle. It specifies constructional requirements for the design of instruments utilizing radioactive sources in regard of radiation protection. This standards cancels and replaces IEC 60405.

Overview

IEC 62598:2011 - "Nuclear instrumentation - Constructional requirements and classification of radiometric gauges" - specifies safety and classification requirements for electrical measuring systems and instruments that use radioactive sources (radiometric gauges) and for associated source housings. The standard focuses on radiation protection and constructional requirements for fixed gauges (not related to power production or the fuel cycle). It cancels and replaces IEC 60405 and introduces updated classification, testing and labelling provisions.

Key Topics and Requirements

Scope & exclusions: Applies to fixed radiometric gauges and stand‑alone source housings; excludes portable gauges and X‑ray tube systems (though principles may be applied analogously).

Gauge classification: Defines three categories:

Category A - gauges with restricted (collimated) beams.
Category B - gauges with omnidirectional beams.
Category C - stand‑alone source housings for fixed gauges (new in this edition).

Dose rate classes and temperature classes: Introduces standardized dose rate classes (replacing former “radiation protection class”) and temperature classes for environmental suitability.

Fire resistance: Adds fire resistance classes and related test requirements for source housings and shutters.

Constructional requirements: Specifies requirements for measuring gaps, source holders, source housings, beam alignment, detector housings and measuring heads to ensure safe containment and operation.

Radiation protection measures: Prescribes shielding, shutter design, and protection against unauthorized use, including indication of shutter position and optional warning devices.

Testing and measurement: Details procedures for dose equivalent rate measurements (closed and open shutter conditions), temperature cycle tests, mechanical and fire resistance tests.

System coding and labelling: Defines a system classification code (including revision and fire-test digits) and labelling requirements; includes documentation and installation guidance (Annex A).

Keywords: IEC 62598, radiometric gauges, constructional requirements, source housings, dose rate classes, radiation protection, fire resistance, testing.

Practical Applications and Users

Manufacturers and designers of fixed radiometric gauges and source housings - to design compliant products.

Installation and maintenance engineers - for correct installation and verification of shielding, alignment and safety devices.

Radiation protection officers and safety managers - to assess dose rates, signage and emergency measures.

Certification and conformity bodies - to perform tests and label systems according to the classification code. Practical applications include level, density and thickness gauges in industrial process control where sealed radioactive sources are used.
