ISO 15029-1-1999 PDF

Full title and description

Petroleum and related products — Determination of spray ignition characteristics of fire-resistant fluids — Part 1: Spray flame persistence — Hollow-cone nozzle method. This International Standard specifies a laboratory test procedure using a hollow‑cone nozzle to assess the persistence of a spray flame produced from fire‑resistant (difficult‑to‑ignite) fluids when dispersed as an atomised spray.

Abstract

ISO 15029-1:1999 defines a standardized method to determine whether and for how long a spray of a fire‑resistant fluid will sustain a flame after ignition when discharged through a hollow‑cone nozzle. The method yields comparative information on spray ignition behaviour useful for product characterization, classification and safety assessment in handling and fire‑risk evaluations.

Scope

This part of ISO 15029 applies to the determination of spray flame persistence of fire‑resistant fluids when atomised by a hollow‑cone nozzle under specified laboratory conditions. It is intended for comparative laboratory evaluation of spray ignition behaviour and is not intended to cover other forms of ignition testing (for example bulk liquid pool fires) or other nozzle types. The standard gives the apparatus arrangement, test procedure, and interpretation of results for the hollow‑cone nozzle method.

Key topics and requirements

• Specification of test apparatus and hollow‑cone nozzle geometry and positioning.
• Controlled spray generation and ignition procedure to produce repeatable atomised sprays.
• Measurement and recording of flame persistence (duration of sustained combustion) following ignition.
• Conditions for acceptance, reproducibility, and reporting of test results.
• Safety and handling notes for working with pressurised sprays and ignitable fluids in the laboratory.

Typical use and users

Used by petroleum and lubricant laboratories, product development teams, regulatory bodies, test houses and safety engineers to compare the spray ignition tendencies of fire‑resistant fluids, support hazard assessments, and inform handling/storage recommendations. Also used by standards committees and manufacturers for product specification and conformity testing.

Related standards

ISO 15029 is a multi‑part series addressing spray ignition characteristics of fire‑resistant fluids. Part 2 of the series (ISO 15029-2:2018) covers a complementary spray test using a stabilised flame heat‑release method; earlier technical specifications and revisions have been issued for Part 2 before the 2018 publication. ISO/TC 28 (petroleum products) is the responsible committee for the series.

FAQ

Q: What is this standard?

A: ISO 15029-1:1999 is an International Standard that specifies a laboratory method (hollow‑cone nozzle method) for determining the persistence of flames produced by sprays of fire‑resistant fluids.

Q: What does it cover?

A: It covers test apparatus, nozzle arrangement, test procedure and reporting for measuring spray flame persistence of atomised fire‑resistant fluids. It is focused on spray ignition behaviour, not bulk liquid fire tests.

Q: Who typically uses it?

A: Test laboratories, manufacturers of fire‑resistant fluids, product safety engineers, regulatory and standards bodies, and researchers assessing spray ignition hazards.

Q: Is it current or superseded?

A: ISO 15029-1:1999 remains the published Part 1 edition from 1999; the ISO entry indicates the publication and review history and confirms the document status following periodic review.

Q: Is it part of a series?

A: Yes — ISO 15029 is a series. Part 2 (ISO 15029-2:2018) provides an alternate/complementary spray test (stabilised flame heat‑release method); other related technical specifications and national/adopted versions exist for different regions.

Q: What are the key keywords?

A: Spray ignition, flame persistence, hollow‑cone nozzle, fire‑resistant fluids, petroleum products, ignitability, spray test.
