dated 22 June 1990
i This Defence Standard specifies the requirements for, and also lists,
equipment wires, having limited fire hazard (LFH) insulation, for Ministry
of Defence use.
ii It is a performance Standard, actual insulation material is not
specified and tests are included to control materials offered for approval.
With the development of new materials and/or constructions it is likely
that additional tests will require to be devised.
iii Tables I(A) to I(E) list the standard range of equipment wires and
cables having a toxicity level as defined in 11.4. Tables II(A) to II(E)
list the maintenance range of equipment wires and cables. They are
manufactured to Issue 2 of this Standard and differ in certain significant
features, including a higher toxicity level.
iv The items listed in this Standard should only be purchased from those
manufacturers holding a current Qualification Approval certificate
applicable to the cable or wire required. A list of manufacturers holding
approval to items specified in this Standard will be included in Def
Stan 59-59 and the EPIC/CODUS data bank.
v Users of this Standard are to note that these items may be claimed to be
subject to patent rights in this or in other countries.
vi This Standard has been agreed by the authorities concerned with its use
and is intended to be used whenever relevant in all future designs,
contracts, orders etc and whenever practicable by amendment to those
already in existence. If any difficulty arises which prevents application
of the Defence Standard, the Directorate of Standardization shall be
informed so that a remedy may be sought.
vii Any enquiries regarding this Standard in relation to an invitation to
tender or a contract in which it is incorporated are to be addressed to the
responsible technical or supervising authority named in that invitation to
tender or contract.
vii This Standard has been devised for the use of the Crown and its
contractors in the execution of contracts for the Crown. The Crown hereby

WARNING
2.1 This Standard calls for the use of substances and/or procedures that
may be injurious to health if adequate precautions are not taken. It
refers only to technical suitability and in no way absolves either the
designer, the producer, the supplier or the user from statutory and all
other legal obligations relating to health and safety at any stage of
manufacture or use.
2.2 Particular attention is drawn to the following hazards although the
list may not necessarily be exhaustive:
2.2.1 Flammable and/or toxic fumes may be given off from the specimens
when subjected to the fire hazard/flammability tests. Operators are to
take appropriate precautions to avoid exposure to the evolved fumes.
2.2.2 Compliance with 10.2.8 (resistance to fluids test) provides no
guarantee that the wires are suitable for continuous use in the specified
fluids.
2.2.2.1 It should be noted that isopropyl alcohol and aircraft fuel are
not specified for Type 2 wires and that certain Type 2 wire insulations are
adversely affected by these fluids.
2.2.3 Due to the wide variety of insulants which may meet this Standard,
particular attention is drawn to clause 5 especially with respect to
selection of Type and size of wire to be used.
