GOST 31169-2003 PDF

Full title and description

GOST 31169-2003 (ИСО 11202:1995). Noise of machines — Measurement of emission sound pressure levels at a work station and at other specified positions. Survey method in situ. The standard defines an approximate (survey) in‑situ method for measuring the emission sound pressure levels produced by machines and equipment at operator work stations and other specified control points close to the machine under typical operating conditions.

Abstract

GOST 31169-2003 specifies a practical, approximate method for determining emission sound pressure levels of machinery on site (in situ). It is intended for use where laboratory conditions are not available and provides measurement geometry, instrumentation guidance, measurement procedures and reporting conventions for estimating sound pressure levels at work places and other control points near the machine. The standard has been superseded by a later harmonized document (GOST ISO 11202-2016).

Scope

Applies to stationary or moving machines and equipment that produce airborne noise in air and where measurements are required on site (at the place of installation) rather than in special acoustic test rooms. The standard covers measurement of emission sound pressure levels at an operator’s work station and at other specified nearby positions using an approximate survey method suited to typical operational conditions. It gives rules on measurement positions, measurement procedure, handling of acoustic environment influences, and presentation of results for engineering, regulatory and occupational hygiene purposes.

Key topics and requirements

• Definition of the survey (in situ) measurement method for emission sound pressure levels at workplaces and other control points close to machines.
• Specification of measurement geometry and recommended positions around the machine and at the operator’s workstation.
• Instrument requirements and recommended calibration/accuracy considerations for sound level meters and frequency analysis (A‑weighting, octave/one‑third octave bands where applicable).
• Procedures for taking representative measurements under typical operating conditions, including handling of background noise and transient events.
• Guidance on averaging, reporting A‑weighted and peak levels, and documenting measurement conditions and uncertainties inherent to the approximate method.
• Limitations of the approximate (survey) method and notes on when more precise laboratory or engineering methods are required.

Typical use and users

Used by acoustic and environmental engineers, occupational hygienists, test laboratories, manufacturers performing on‑site noise assessments, safety and regulatory officers, and consultants conducting conformity checks or producing noise data for technical documentation. Typical applications include workplace noise assessments, pre‑compliance surveys, baseline measurements during installation, and noise reporting where full sound power or specialist chamber testing is not feasible.

Related standards

Closely related or complementary standards include ISO 11202:1995 (basis for this GOST), the successor national implementation GOST ISO 11202-2016 (which superseded GOST 31169-2003), and other machine-noise standards and test codes such as GOST 31171-2003, GOST 31172-2003, GOST 31275-2002 and GOST 31277-2002. It is also used together with workplace measurement and instrumentation standards (e.g., national standards on sound level meters, octave filters and measurement uncertainty) and with broader standards on noise test codes for specific machine groups.

FAQ

Q: What is this standard?

A: GOST 31169-2003 is an interstate (GOST) standard that defines an approximate/in‑situ survey method for measuring emission sound pressure levels of machines at operator workstations and other specified nearby positions. It is based on ISO 11202.

Q: What does it cover?

A: It covers on‑site measurement geometry, instrumentation guidance, measurement procedures, handling of background noise and reporting conventions for estimating emission sound pressure levels of machinery under typical operating conditions. It is intended as a practical survey method rather than a precision laboratory procedure.

Q: Who typically uses it?

A: Acoustic engineers, occupational hygienists, test laboratories, manufacturers, safety officers and consultants performing workplace noise surveys, product noise reporting and preliminary compliance checks use this standard.

Q: Is it current or superseded?

A: GOST 31169-2003 has been superseded. It was approved in December 2003 and introduced into action on 1 October 2005; it was withdrawn and replaced by GOST ISO 11202-2016 (new national implementation) with effect from 1 November 2017.

Q: Is it part of a series?

A: Yes. It belongs to a family of machine‑noise measurement standards (several GOST/ISO documents addressing different measurement methods and test codes), including related GOSTs that cover selection of method, engineering/precision methods and specific test codes for machine groups.

Q: What are the key keywords?

A: Machine noise, emission sound pressure level, in situ survey, workplace noise measurement, approximate method, operator workstation, acoustic measurement, measurement uncertainty.
