Abstract

This standard defines general technical requirements for indicating and recording pressure-measuring instruments (pressure gauges, vacuum gauges, combined devices and draft gauges). It covers constructional characteristics, allowable working ranges and accuracy classes, environmental and safety requirements, testing and verification procedures, marking and documentation. The standard was prepared and approved by the State Committee for Standards of the USSR and introduced into force on 1 July 1989.

General information

• Status: Listed in many catalogs as an established GOST; some registries and commercial databases show it as active (действующий) while a few commercial listings mark changes or withdrawal entries in catalogue metadata — users should check the current national registry for final legal status in their jurisdiction.
• Publication date: Introduced into force 01 July 1989 (designation year 1988).
• Publisher: Originally approved and published by the State Committee of the USSR for Standards (Gosstandart); maintained / referenced in successor national catalogs and standards services.
• ICS / categories: ICS 17.100 (Measurement of force, weight and pressure / pressure measuring instruments).
• Edition / version: ГОСТ 2405-88 (original 1988 designation; entered into force 1989).
• Number of pages: Varies by publisher/extract: commercial listings report publication lengths typically in the range of ~30–60 pages depending on formatting/version (examples: 33 pages and 56 pages reported by different providers).

Scope

Applies to indicating (showing) and self-recording pressure-measuring instruments — including pressure gauges, vacuum gauges, combined pressure-and-vacuum instruments, draught (draft) gauges and draught-and-pressure gauges — intended to measure gauge and vacuum pressure of liquids, gases and steam. The standard excludes reference (etalon) instruments, differential pressure gauges and instruments specifically designed for pulsating-pressure measurement unless otherwise specified in a particular technical specification (TU). It also sets environmental, safety and test conditions for normal operation, storage and transport.

Key topics and requirements

• Types of instruments covered: indicating and self-recording manometers, vacuum gauges, manovacuum gauges, draught and draught-pressure gauges.
• Metrological characteristics: accuracy classes (various classes defined), permissible basic errors, scale division and range selection rules.
• Environmental and mechanical requirements: temperature ranges, humidity, vibration/impact limits, mounting orientation and shock resistance categories (includes references to climatic and mechanical standards such as ГОСТ 15150 and ГОСТ 12997).
• Ingress protection and explosion-proof variants: classification of enclosures and degree of protection referencing GOST 14254 and related safety standards for hazardous environments.
• Constructional and dimensional requirements: case diameters, flange and panel cut-out dimensions, mounting interfaces and materials for wetted parts (including special requirements for oxygen service).
• Testing, acceptance and verification: pressure and vacuum testing methods, procedures for checking pointer movement and signal devices; routine test frequency and verification intervals (periodicity of periodic verification is specified).
• Marking, documentation and packaging: required markings (type, range, accuracy class, manufacturer, year), test certificates and packaging requirements to withstand transport conditions.

Typical use and users

Manufacturers of pressure-measuring instruments, calibration and metrology laboratories, procurement/specification engineers and technical departments across industries such as oil & gas, petrochemical, power generation, HVAC, water treatment, steam systems and industrial process control. The standard is used as a baseline technical/specification document for design, testing, acceptance and procurement of pressure and vacuum gauges in industrial and commercial equipment.

Related standards

GOST 2405-88 replaces and consolidates a number of earlier GOSTs (for example GOST 2405-80 and several other specific documents for instrument types). It also references and depends on numerous related normative documents for testing, safety and environmental classifications (examples include GOST 15150, GOST 12997, GOST 14254 and several ST SEV intergovernmental standards cited in the text). Users should consult the normative references in clause listings for full cross-references.

FAQ

Q: What is this standard?

A: GOST 2405-88 is a Soviet-era national standard that defines general technical requirements for indicating and self-recording pressure- and vacuum-measuring instruments (manometers, vacuum gauges, combined gauges and draught gauges). It was prepared under the State Committee for Standards of the USSR and brought into force on 01 July 1989.

Q: What does it cover?

A: The standard covers instrument types, metrological characteristics (accuracy classes, permissible errors), construction and dimensional requirements, environmental and mechanical performance, safety requirements, testing and verification procedures, marking and packaging. It also lists normative references to other GOSTs and intergovernmental standards used for test and safety methods.

Q: Who typically uses it?

A: Instrument manufacturers, quality and metrology laboratories, procurement/specification engineers, and industrial users in sectors such as oil & gas, power, chemical, HVAC and general process industries that require standardized pressure/vacuum measurement equipment.

Q: Is it current or superseded?

A: Catalog entries vary: many standards catalogs list GOST 2405-88 as the active/established document replacing earlier versions (e.g., GOST 2405-80), while some commercial databases show administrative notes or withdrawal metadata. Because national adoption and legal status can change, verify the current legal/registry status with the official national standards body (successor registries such as Rosstandart or the applicable national catalogue).

Q: Is it part of a series?

A: Yes — GOST 2405-88 consolidates and replaces earlier GOST documents for pressure- and vacuum-measuring instruments and references a set of related GOST and ST SEV standards for test methods, climatic categories and safety requirements. It functions as the general technical specification within a family of standards for pressure-measuring devices.

Q: What are the key keywords?

A: Pressure gauge, vacuum gauge, manovacuumeter, accuracy class, metrological tests, marking, IP protection, draught gauge, GOST 2405-88.
