Full title and description

STB BS EN ISO 10370-2014 (BS 2000-398-2014) — Petroleum products. Determination of carbon residue — Micro method. This publication is the British adoption of ISO 10370:2014 and specifies a laboratory micro-method to determine the amount of carbon residue left after evaporation and pyrolysis of petroleum products under defined conditions.

Abstract

Specifies a micro method for determining carbon residue in petroleum products over the range 0.10 % (m/m) to 30.0 % (m/m). The measured carbon residue approximates the tendency of a product to form carbonaceous deposits; results above 0.10 % (m/m) are equivalent to the Conradson carbon residue test (ISO 6615) in the 0.10–25.0 % range. The procedure includes preparation of a 10 % (V/V) distillation residue for very low-residue distillate materials and notes the influence of ash-forming constituents and non‑volatile additives on the reported residue. Precautions are given for products containing organic (alkyl) nitrates.

Scope

Defines a laboratory micro-method for quantifying carbon residue left after controlled evaporation and pyrolysis of petroleum products. Applicable to a wide range of hydrocarbon materials (including distillate materials, where a 10 % (V/V) distillation residue is prepared prior to test). The method provides results that are comparable to the Conradson test over a specified range and includes guidance on factors (ash-forming constituents, non‑volatile additives, organic nitrates) that affect the measured residue.

Key topics and requirements

• Sample preparation and, where necessary, preparation of a 10 % (V/V) distillation residue for low-residue distillates.
• Apparatus and equipment: micro vials, controlled furnace program to about 500 °C, inert gas (nitrogen) flow to sweep volatiles, weighing procedures.
• Measurement range: nominally 0.10 % (m/m) to 30.0 % (m/m).
• Equivalence and correlation: results comparable to Conradson carbon residue (ISO 6615) in the 0.10–25.0 % range; see informative annex for details.
• Reporting considerations: carbon residue includes contributions from ash-forming constituents and non-volatile additives (ISO 6245 referenced).
• Interferences and checks: organic/alkyl nitrates can give abnormally high residues — detection referenced to ISO 13759.
• Precision, repeatability and measurement uncertainty guidance appropriate for routine petroleum laboratory quality control.

Typical use and users

Used by petroleum and fuel testing laboratories, refinery quality-control units, petrochemical producers, additive manufacturers, research and development groups, and regulatory/standards bodies concerned with fuel and lubricant deposit-forming tendencies. Typical applications include product quality control, comparative screening of fuels/lubricants, and formulation or stability studies.

Related standards

Commonly referenced/related documents include ISO 6615 (Conradson carbon residue), ISO 6245 (determination of ash-forming constituents), ISO 13759 (detection of organic nitrates / alkyl nitrates), and ISO 3405 (distillation procedures used when preparing distillation residues). The BS/EN adoption aligns this document with the EN/ISO family for petroleum product test methods.

FAQ

Q: What is this standard?

A: BS EN ISO 10370:2014 (BS 2000-398:2014) is the British adoption of ISO 10370:2014 — an international standard that specifies a micro-method for determining carbon residue in petroleum products after controlled evaporation and pyrolysis.

Q: What does it cover?

A: It covers sample preparation, apparatus, heating program (to ~500 °C under inert gas), measurement procedures, reporting, and factors affecting results (including ash-formers, non-volatile additives and organic nitrates). It gives a measurement range (0.10–30.0 % m/m) and notes equivalence to the Conradson method over a defined range.

Q: Who typically uses it?

A: Routine and specialized petroleum testing laboratories, refineries, fuel and lubricant manufacturers, additive suppliers, R&D groups and regulatory laboratories that assess deposit-forming tendencies and perform quality control on hydrocarbon products.

Q: Is it current or superseded?

A: The 2014 edition (ISO edition 2) is the current edition as published; ISO records show the 2014 edition confirmed in periodic reviews and corrective information recorded where applicable. The BS adoption (BS EN ISO 10370:2014 / BS 2000-398:2014) reflects that adoption. Users should check with the national standards body or publisher for any more recent amendments or national corrigenda.

Q: Is it part of a series?

A: It belongs to the family of petroleum product test methods and is related to other residue and characterization standards (for example ISO 6615 for Conradson carbon residue). It is commonly published alongside other EN/ISO petroleum testing standards.

Q: What are the key keywords?

A: Carbon residue, micro method, petroleum products, Conradson equivalence, pyrolysis, deposit tendency, fuel testing, ash-forming constituents.
