ISO 10054-1998 PDF

Full title and description

ISO 10054:1998 — Internal combustion compression-ignition engines — Measurement apparatus for smoke from engines operating under steady-state conditions — Filter-type smokemeter. This International Standard specifies the required characteristics, performance and use of filter-type smokemeters (instruments that determine soot content by blackening a filter) for steady‑state testing of compression‑ignition (diesel) engines.

Abstract

ISO 10054:1998 defines the physical and operational characteristics of filter-type smokemeters used to determine soot content of exhaust from reciprocating compression‑ignition engines under steady‑state conditions. It describes sampling and measurement principles, calibration and reporting (filter smoke number, FSN), and notes limitations (not intended for transient testing or aircraft engines).

• Edition / version: Edition 1 (1998).
• Number of pages: 16 pages (commonly listed as 16 pages in national catalogues).

Scope

Specifies characteristics required for apparatus to measure soot in exhaust gas of reciprocating compression‑ignition engines operating under steady‑state conditions by the filter‑blackening method (filter‑type smokemeters). It excludes apparatus intended for transient testing and excludes aircraft engines; when used under transient conditions results from different instrument types are not directly comparable unless sampling conditions are identical.

Key topics and requirements

• Definition and principle of filter‑type smokemeter (filter smoke number — FSN).
• Required physical characteristics of the sampling/filter assembly (filter area, swept volume, dead volume considerations).
• Sampling method and conditioning for steady‑state engine tests (probe/tube arrangement, flow control, temperature considerations).
• Calibration intervals and procedures (regular calibration recommended; calibration best practice noted).
• Reporting format and required test information (engine conditions, instrument details, ambient conditions, FSN reporting).
• Limitations and comparability statements — not for transient tests nor for aircraft engines; comparability requires identical sampling conditions.

Typical use and users

Used by engine and equipment manufacturers, emissions test laboratories, certification bodies, research institutes and regulatory authorities for steady‑state smoke testing of diesel/compression‑ignition engines. National and regional regulators and test programs may reference or recommend ISO 10054 for filter‑type smokemeter testing (for example in guidance on steady‑state smoke testing).

Related standards

Closely related documents include the ISO 8178 series (exhaust emission measurement methods, opacimeter and smoke measurement methods) and ISO 11614 (apparatus for opacity measurement and determination of light‑absorption coefficient). These standards are produced by the same ISO technical committee area and are commonly used together in engine emissions testing programs.

FAQ

Q: What is this standard?

A: ISO 10054:1998 is an International Standard that specifies the requirements and use of filter‑type smokemeters for measuring soot in the exhaust of compression‑ignition engines under steady‑state conditions.

Q: What does it cover?

A: It covers instrument characteristics, sampling arrangements, measurement and reporting of filter smoke number (FSN), calibration and limitations (not intended for transient tests or aircraft engines).

Q: Who typically uses it?

A: Engine and equipment manufacturers, test laboratories, regulatory and certification bodies, and research organisations involved in steady‑state smoke testing of diesel/compression‑ignition engines. Regulatory guidance may recommend or reference this ISO method for filter‑type smokemeter use.

Q: Is it current or superseded?
