NES 711 Issue 2 (Reformatted)
SCOPE
1. This NES gives details of one of a series of test methods for determining the combustion characteristics of materials. The test explores the smoke production potential of a small sample of material under specified conditions of pyrolysis and combustion. It does not necessarily indicate the smoke production under other thermal exposure conditions. The test is useful for the quality control of materials and for research and development. It may be used to compare the combustion characteristic of a series of materials. Combustion characteristics tests alone are not suitable for assessing the total fire hazard of products but may be used to specify a quality of a raw material or product. The method is based on that developed by the American National Bureau of Standards and described by Gross D, Loftus J J and Robertson A F in ASTM Special Technical Publication No 422, 166−204(1967), but modifications have been incorporated as a result of work carried out at AMTE (Dockyard Laboratory), Portsmouth. NOTE. STP No 422, 166−204(1967) is superseded by ASTM E662:1979 Specific Optional Density of smoke generated by solid materials.
The issue and use of this Standard is authorized for use in MOD contracts by MOD(PE) Sea Systems and the Naval Support Command

FOREWORD Sponsorship
1. 2. This Standard is sponsored by the Procurement Executive, Ministry of Defence, Ship Department, Section D 123a, Foxhill, Bath BA1 5AB. This Naval Engineering Standard (NES) is to be applied as required by any Procurement Executive, Ministry of Defence contract for determining the Smoke Index of the products of combustion from small specimens of materials. If this Standard is found to be technically unsuitable for any particular requirement the sponsor is to be informed of the circumstances with a copy to Ship Department Section D 191a. Any user of this Standard either within MOD or in outside industry may propose a change to an NES. Proposals for changes which are: a. b. 5. 6. not directly applicable to a particular contract are to be made to the sponsor or the NES directly applicable to a particular contract are to be dealt with using existing departmental procedures or as specified in the contract.
