GOST 33453-2015 PDF

Full title and description

GOST 33453-2015 — Methods of testing chemical products presenting environmental hazard. Determination of the density of liquids and solids. The standard specifies laboratory methods for measuring the density of liquid and solid chemical substances (including mixtures and aerosols after liquid recovery) to support environmental hazard assessment and fate/transport evaluations.

Abstract

This interstate (GOST) standard, adopted into the Russian national system, defines accepted procedures and measurement conditions for determining density using hydrometric (areometric), immersed-body, pycnometric, air-pycnometric and vibrating-densitometer methods. It sets test conditions (notably reference temperature), reporting requirements, and limits of applicability for each method to ensure reproducible density data for environmental assessment.

General information

• Status: Active / Introduced (first edition).
• Publication date: Introduced into force 1 September 2016 (designated GOST 33453-2015).
• Publisher: Adopted and published under the authority of the Federal Agency on Technical Regulation and Metrology (Rosstandart) as an interstate standard prepared by the Interstate Technical Committee; introduced by Rosstandart order.
• ICS / categories: ICS 13.020.01 (Environment protection / environmental testing); group T58.
• Edition / version: 2015 (first issue — GOST 33453-2015; degree of correspondence to OECD Test No. 109:2012 — modified).
• Number of pages: 8 pages (concise test-method standard).

Scope

The standard establishes laboratory methods for determination of the density of liquids and solid substances (including certain aerosols after conversion to liquid) used in evaluating the environmental behaviour of hazardous chemicals. It covers method selection criteria, test conditions (preferred test temperature, repeat measurements), standard materials for calibration and the form and content of test reports. The methods are intended for use in environmental hazard testing and may be applied where reliable density values are required for transport, partitioning and exposure assessments.

Key topics and requirements

• Specified measurement methods: areometric (hydrometer), immersed-body (buoyancy) method, pycnometric (glass pycnometer) method, air (gas) pycnometer for solids, and vibrating-tube densitometry.
• Recommended test temperature and thermal control (tests commonly performed at 20 °C; temperature control and reporting required).
• Applicability limits tied to liquid viscosity and sample state (method choice depends on dynamic viscosity and physical form).
• Calibration and use of standard reference liquids and procedures for verification of instrument performance.
• Reporting requirements: identification of substance, method used, results as mean of replicate measurements, precision/uncertainty assessment, and notes on impurities or physical state affecting interpretation.

Typical use and users

Primary users are analytical and environmental testing laboratories, chemical manufacturers, regulatory bodies and consultants performing environmental hazard, fate and transport assessments, and conformity testing. The standard supports data generation for regulatory dossiers, safety data sheets and environmental risk assessments.

Related standards

GOST 33453-2015 is based on and modified from OECD Test No. 109:2012 (Density of Liquids and Solids). The standard references related international and national test methods (examples include ISO 758 and various ASTM methods such as ASTM D1298) and lists applicable instrumentation and calibration standards in its informative annex.
