The work of preparing International Standards is normally carried out through isO technical liaison withIsO,also takepart inthework.IsO collaboratesclosely withtheInternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3 Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. International Standard ISO 15029-1 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants. ISO 15029 consists of the following parts, under the general title Petroleum and related products - Determination ofsprayignitioncharacteristicsoffire-resistantfluids: Part 1: Spray flame persistence -Hollow-cone nozzle method Part 2: Spray test - Stabilized flame heat release method Part 3: Spray test Large scale method In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. One type of such a liquid is fire-resistant fluid. The following International Standards are suitable for the classification, specification and guidance for use of such fluids: ISO 6743-4:1999, Lubricants, industrial oils and related products (class L) — Classification — Part 4: Family H (Hydraulic systems). ISO 7745:1989, Hydraulic fluid power Fire-resistant (FR) fluids — Guidelines for use. ISO 12922:1999, Lubricants, industrial oils and related products (class L) — Family H (Hydraulic systems) - Specifications for categories HFAE, HFAS, HFB, HFC, HFDR and HFDU. The following International Standard may be useful for the assessment of the flame propagation and persistence of a flame applied to the edge of a wick of non-flammable material immersed in fire-resistant fluid: @ISO1999 All rights reserved.

This part of Iso 15029 does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This part of isO 15029 specifies a hollow-cone nozzle method for the assessment of the persistence of a flame applied to various points within a pressurized spray of fire-resistant fluid. This part of IsO 15029 is one of two basic measures of fire-resistance, and may be called up in regulations governing their use under the 7th edition of the Luxembourg Report1). 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of
