GOST 8.009-84 PDF

Full title and description

GOST 8.009-84 — Государственная система обеспечения единства измерений (ГСИ). Нормируемые метрологические характеристики средств измерений. (English title: State system for ensuring the uniformity of measurements — Standardized metrological characteristics of measuring instruments). The standard establishes a uniform nomenclature, methods for normalization and rules for presentation of metrological characteristics used to describe, evaluate and document the performance of measuring instruments.

Abstract

GOST 8.009-84 defines the set of metrological characteristics (МХ) to be used in normative-technical documentation for measuring instruments, prescribes rules for selecting complexes of normalized characteristics for specific instrument types, describes methods for normalizing these characteristics and specifies forms for their presentation. The standard contains mandatory and informative appendices with required complexes of characteristics, statistical definitions of error components, terminology, full dynamic characteristics and examples of normalization.

Scope

The standard applies to measuring instruments (means of measurement) and sets out the nomenclature of metrological characteristics, rules for choosing normalized characteristic complexes for particular instrument types and techniques for normalizing characteristics in normative-technical documentation (standards, technical requirements, technical specifications and development assignments). It does not apply to reference standards (etalon), reference installations and instruments developed as reference prototypes.

Key topics and requirements

• Definition and nomenclature of metrological characteristics (accuracy, systematic and random components, repeatability, reproducibility, hysteresis, variation, dynamic error components, influence quantities, etc.).
• Rules for selecting complexes of normalized metrological characteristics (NМХ) appropriate to the instrument type and intended application.
• Methods for normalization: permissible limits, statistical descriptors, allowable variations and presentation of limits in normative documents.
• Forms and recommended formats for presenting normalized characteristics in standards and technical documentation.
• Mandatory appendices with required sets of characteristics for specific instrument classes and mandatory mathematical/statistical definitions for error components.
• Informative appendices with terminology, complete dynamic characteristics and practical examples of normalization and calculation of instrumental error components.

Typical use and users

Primary users are metrologists, standards developers and engineers in instrument design and manufacturing. Other typical users include test and calibration laboratories, certification bodies, quality assurance specialists and regulatory authorities involved in verification, acceptance testing, calibration and documentation of measuring instruments.

FAQ

Q: What is this standard?

A: GOST 8.009-84 is a GSI (state metrology) standard that defines the standardized metrological characteristics for measuring instruments and prescribes how those characteristics are to be normalized and documented in normative-technical documents.

Q: What does it cover?

A: It covers the nomenclature of metrological characteristics, rules for selecting complexes of normalized characteristics for specific instrument types, methods for normalizing characteristics, and the required presentation forms. It includes mandatory and informative appendices with statistical definitions, dynamic characteristics and examples.

Q: Who typically uses it?

A: Metrologists, instrument designers and manufacturers, calibration and test laboratories, certification bodies, standards developers and regulatory agencies use it to specify, evaluate and document instrument performance.
