This document specifies a method for the assessment of the persistence of a flame applied to the edge of a wick of non-flammable material immersed in fire-resistant fluid. The test relates to the bulk behaviour of a fluid, which may provide pertinent information for safe transportation and storage.

This test does not determine the behaviour of a spray of fire-resistant fluid (see Introduction).

This document establishes one of two basic measures of fire-resistance, and may be called up in regulations governing the use of fire resistant hydraulic fluids under ISO 12922 [1].

This document does not apply to certain water-containing fluids or emulsions that do not adhere to the test board.

1   This document describes the design, use and calibration of volumetric measures (capacity measures) which are intended for use in fixed locations in a laboratory or in the field. It also covers portable and mobile measures. The scope covers applications particularly, but not exclusively, in the petroleum industry. Volumetric measures are classified as test measures or prover tanks depending on capacity and design.  

1.2   The document excludes pressurised measures as used for LPG and LNG and measures for cryogenic liquids. Measures described in this document are primarily designed, calibrated and used to measure volumes "to deliver", i.e. wetted and drained for a specified time before use. Many of the provisions will however apply equally to measures which are used "to contain", i.e. to measure a volume using a clean and dry measure.

1.3   Annex A provides a reference for formulae describing the properties of water and other materials used to define volume. This includes density, thermal expansion, compressibility and viscosity for pure, impure and saline water. It also provides property information for hydrocarbon liquids and materials used to construct measures.

1.4 Guidance is given regarding commonly expected uncertainties and calibration specifications.
