GOST 26021-83 PDF

Full title and description

GOST 26021-83 — "Electrical fuel level indicators for motor vehicles. Technical requirements and test methods". The standard specifies technical requirements, accuracy limits and test methods for electrical (remote, rheostatic) fuel level indicators intended for installation in general-purpose motor vehicles.

Abstract

Defines constructional and metrological requirements, permissible basic errors at key pointer positions, environmental and durability tests, and methods for verifying compliance of fuel level sensors and indicating instruments used in automotive applications. Includes references to related GOST normative documents and recorded amendments.

Scope

Applies to electrical remote fuel-level indicators composed of a rheostat-type sender (sensor) and a showing instrument intended for installation on general-purpose motor vehicles. The standard does not cover indicators developed before 01 January 1985 where noted by amendment. It establishes requirements for accuracy, environmental performance and test procedures to demonstrate compliance.

Key topics and requirements

• Definitions of component parts: sender (rheostat sensor) and indicating instrument.
• Permissible basic errors at key pointer positions (e.g., "Empty", "Half", "Full") and their percentage limits.
• Electrical and mechanical performance requirements including contacts, insulation, and resistance ranges.
• Environmental and climatic durability tests (temperature, vibration, humidity) and test methods for repeatability and stability.
• Reference normative documents required for conformity (other GOSTs for instrumentation and testing).

Technical content and error limits are specified in the standard text and accompanying tables.

Typical use and users

Used by automotive manufacturers, instrument and sensor producers, quality and test laboratories, certification bodies, and repair/service organizations when designing, producing, testing or certifying electrical fuel level indicators for vehicles intended for markets recognizing GOST standards. Also referenced by technical authors of vehicle maintenance documentation and regulatory compliance specialists.

Related standards

Cross-references include other GOSTs covering automotive instrumentation, test methods and electrical equipment (examples cited in the standard: GOST 3940-84, GOST 25651-83 and regional standards such as ST CЭV 3043-81). Later national or industry regulations for vehicle instruments (for example GOST R variants) may also be relevant when applying or updating requirements.

A: GOST 26021-83 is a national (interstate) standard that sets technical requirements and test methods for electrical fuel level indicators used in motor vehicles.

Q: What does it cover?

A: It covers the constructional, electrical and metrological requirements for rheostat-type senders and their indicating instruments, permissible basic errors at specified pointer positions, and the tests needed to verify performance and durability.

Q: Who typically uses it?

A: Automotive OEMs, instrument and sensor manufacturers, testing laboratories, certifiers and service/repair organizations working with vehicle fuel-level instrumentation in regions where GOST standards apply.

Q: Is it current or superseded?

A: As recorded in public standards catalogues, GOST 26021-83 is listed as active/in force with noted amendments (entry into force 01 January 1985). Users should check the latest national registry or publisher for any subsequent revisions or replacements before applying the standard.
