ISO 3405-1975 rus PDF

Full title and description

St ISO 3405-1975 rus — national (Russian language) edition of ISO 3405:1975, "Petroleum products — Determination of distillation characteristics". This document specifies a laboratory procedure for determining the distillation (boiling-range/volatility) characteristics of petroleum distillates using standardized atmospheric distillation techniques. The Russian version is a translation/adoption of the original ISO text intended for use by Russian-speaking laboratories and organisations.

Abstract

ISO 3405:1975 defines a method for the determination and reporting of distillation characteristics of petroleum products. The procedure covers laboratory apparatus, sample preparation, test conditions, stepwise distillation to defined fraction recovery points, calculation and presentation of results, and typical reporting formats. The 1975 edition has since been withdrawn and later revised, but the core intent remains: to provide reproducible, comparable boiling‑range data for fuels and middle distillates used in quality control, specification and regulatory testing.

General information

• Status: Withdrawn (revised and superseded by later editions).
• Publication date: February 1975 (ISO reference: ISO 3405:1975).
• Publisher: International Organization for Standardization (ISO); Russian-language national edition issued as Ст ISO 3405-1975 (translation/adoption).
• ICS / categories: 75.080 — Petroleum products in general.
• Edition / version: Edition 1 (1975).
• Number of pages: 13 (original ISO document).

Scope

This standard applies to laboratory determination of distillation characteristics (boiling-range) of petroleum-derived liquids and related products having initial boiling points above ambient and end-points typically below about 400 °C. It establishes the apparatus, test procedure and reporting method for atmospheric-pressure distillation used to determine fractional recovery temperatures and the overall boiling-range behaviour of fuels and distillates for quality control and specification purposes.

Key topics and requirements

• Specified laboratory apparatus and glassware for atmospheric distillation tests (boiling flask, column, condenser, receiver with volumetric marking).
• Sample conditioning and handling requirements to ensure representative and reproducible results.
• Stepwise distillation procedure defining recovery fractions (expressed as % by volume) and corresponding temperatures to be recorded.
• Requirements for test temperature measurement, calibration and correction (thermometer placement, correction tables or formulae).
• Instructions for calculation, interpolation of temperatures for specified percent recoveries and presentation of results (boiling-point curve/boiling-range table).
• Precision, repeatability considerations and basic statements on sources of error and test limitations.

Typical use and users

Used by petrochemical and fuel testing laboratories, refineries, fuel producers, quality assurance groups, regulatory bodies and standards organizations. Typical applications include product specification verification, incoming‑goods inspection, blend control, research into distillation behaviour and comparison of fuels and solvents. National translation/adoption (St ISO 3405-1975 rus) makes the method accessible to Russian‑language users for routine laboratory work.

Related standards

Later revisions of the same ISO series (for example ISO 3405:1988 and subsequent editions) update and replace the 1975 text. Comparable test methods from other bodies include ASTM D86 (Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure) and national adoptions/variants that adapt detail or reporting conventions. For up‑to‑date practice consult the most recent ISO 3405 edition.

FAQ

Q: What is this standard?

A: ISO 3405:1975 is an international laboratory method for determining the distillation (boiling‑range) characteristics of petroleum products. "St ISO 3405-1975 rus" denotes a Russian-language adoption/translation of that 1975 ISO edition.

Q: What does it cover?

A: It covers apparatus, sample preparation, the stepwise atmospheric distillation procedure, temperature measurement and correction, calculation and reporting of distillation data (temperatures at specified volume recoveries and overall boiling-range information).

Q: Who typically uses it?

A: Fuel and petrochemical testing laboratories, refineries, product manufacturers, quality control personnel, and regulators use the method to characterise fuels and distillates and to verify compliance with product specifications. The Russian edition is intended for Russian‑language users in the same roles.

Q: Is it current or superseded?

A: The 1975 edition has been withdrawn and revised by later editions (for example ISO 3405:1988 and further updates). Users should adopt the latest published edition of ISO 3405 for current testing practice and regulatory compliance.

Q: Is it part of a series?

A: Yes — ISO 3405 is part of a family of standards and test methods dealing with petroleum product properties and test procedures; the document has later revisions and is complemented by related standards (including national and ASTM methods) covering distillation and other fuel properties.

Q: What are the key keywords?

A: Distillation, boiling-range, petroleum products, volatility, atmospheric distillation, ISO 3405, fuel testing, Ст ISO 3405-1975.
