O’z DSt 8.033:2009 PDF

Full title and description

O’z DSt 8.033:2009 — State system for ensuring the uniformity of measurements of the Republic of Uzbekistan. The mass of crude oil and petroleum products. Measurement technique for direct dynamic measurement method.

Abstract

This national procedure describes requirements and a step‑by‑step technique for performing measurements of the mass of crude oil and petroleum products using the direct dynamic measurement method (dynamic flow/mass measurement). The document covers metrological principles, measurement sequence, corrections for density/temperature/viscosity effects, and procedures to calculate mass flow in dynamic (in‑motion) conditions.

Scope

Applies to measurement procedures for determining the mass of crude oil and petroleum products by direct dynamic (in‑flow) methods. The standard is intended for use where dynamic mass measurements are required (for example, custody transfer, pipeline transport, loading/unloading operations) and specifies metrological requirements, measurement steps, and factors to be accounted for (temperature, density, viscosity, instrument calibration and uncertainty estimation).

Key topics and requirements

• Definitions and terms related to mass and dynamic measurement of petroleum products.
• Stepwise measurement technique for direct dynamic (in‑flow) mass measurement systems.
• Required corrections for temperature, density and viscosity to obtain mass from volumetric/density signals.
• Instrument and sensor requirements, calibration and verification practices appropriate for dynamic measurement.
• Procedures for calculating mass flow, handling transient conditions and estimating measurement uncertainty.

Typical use and users

Used by metrology laboratories, pipeline and terminal operators, oil companies, custody transfer technicians, calibration/verification specialists, and regulatory inspectors responsible for ensuring correct mass measurement of crude oil and petroleum products in dynamic (flowing) systems.

FAQ

Q: What is this standard?

A: A national Uzbekistan state standard (O’z DSt 8.033:2009) that defines the method and metrological requirements for measuring the mass of crude oil and petroleum products using a direct dynamic (in‑flow) measurement technique.

Q: What does it cover?

A: It covers the measurement procedure, required corrections (temperature, density, viscosity), instrument and calibration requirements, calculation of mass flow and guidance for uncertainty assessment in dynamic measurement conditions for oil and oil products.

Q: Who typically uses it?

A: Oil companies, pipeline operators, terminals, metrology and calibration laboratories, custody transfer specialists, and regulators involved in the accurate measurement of oil/petroleum product mass during flow operations.

Q: Is it current or superseded?

A: Listings show O’z DSt 8.033:2009 as an active (действующий) document in public standards catalogues; users should confirm with the national standards authority for any amendments or more recent replacements before applying the method in legally binding or custody transfer situations.
