Petroleum and related products - Determination of wick flame persistence of fire-resistant fluids (ISO/DIS 14935:2019)
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.
