GOST 17.2.4.06-90 PDF

Full title and description

GOST 17.2.4.06-90 — Nature protection. Atmosphere. Methods for determination of velocity and flowrate of gas-and-dust streams from stationary sources of pollution. The standard specifies measurement procedures and requirements for determining the velocity and volumetric flow of gas–dust (gas-and-dust) streams exhausted from stationary pollution sources (gas ducts and ventilation systems).

Abstract

This interstate (GOST) standard defines accepted methods for measuring the speed and volumetric flowrate of gas‑and‑dust streams emitted from stationary industrial sources. It covers instrument types and measuring procedures (including dynamic pressure / velocity measurements), selection and arrangement of sampling/measuring points in ductwork, calculation of volumetric flow, and conditions for valid measurements. The standard is intended to support regulatory monitoring of atmospheric emissions and to ensure comparability of measurements performed for environmental reporting and compliance.

Scope

Specifies standardised methods for determining the velocity and volumetric flow of gas‑and‑dust streams leaving stationary sources of pollution in gas ducts and ventilation systems. The procedures are intended for gas streams with velocities of 4 m/s and above and include guidance on measurement placement, instruments, and calculation of flowrate to be used for environmental monitoring and regulatory compliance measurements.

Key topics and requirements

• Defined measurement principles for velocity determination (dynamic pressure / velocity measurement methods, e.g., Pitot-type measurements and equivalent devices).
• Procedures for selection and arrangement of measuring points across duct cross-sections to obtain representative velocity profiles.
• Calculation methods to convert measured velocities to volumetric flowrate (including use of cross‑section area and averaging procedures).
• Minimum flow/velocity applicability (applies to gas streams with speed ≥ 4 m/s) and conditions for valid sampling.
• Requirements for instruments, calibration, and measurement uncertainty minimisation (instrument suitability for dusty gases).
• Procedures for correcting measurements for temperature/pressure where needed for volumetric calculations.

Typical use and users

Used by environmental and emissions monitoring laboratories, industrial hygienists, air‑quality engineers, stationary source emission inspectors, consultants performing stack testing, and regulatory bodies in Russia and other CIS states for compliance measurements, permitting, and emission inventories. The standard is routinely referenced in procurement and tender documents for measurement services and equipment selection.

FAQ

Q: What is this standard?

A: GOST 17.2.4.06-90 is an interstate (GOST) standard that sets out accepted methods for measuring the velocity and volumetric flow of gas‑and‑dust streams emitted from stationary pollution sources (gas ducts and ventilation systems).

Q: What does it cover?

A: It covers measurement principles (dynamic pressure/velocity methods), arrangement of measuring points across duct cross sections, calculation of volumetric flow from measured velocities, instrument requirements and calibration considerations, and applicability limits (e.g., gas stream velocities ≥ 4 m/s).

Q: Who typically uses it?

A: Environmental consultants, stack/stack‑testing teams, industrial emissions laboratories, plant environmental departments, permitting authorities and other organisations conducting or regulating stationary source emissions monitoring in Russia and adjoining jurisdictions. The standard is actively referenced in procurement/tender documentation for measurement services.

Q: Is it current or superseded?

A: The standard is listed as active / in force (действует). It was approved in 1990 and introduced on 01 January 1991; later reprints and compilations are recorded in standards catalogues. Users should verify whether any newer national or regional regulations add requirements beyond this GOST when performing formal compliance measurements.
