scope:

This Defence Standard (Def Stan 47-032) specifies the requirements, for Material Performance Type Testing, Manufacture and Production Testing of wire braided rubber hose to operate over a temperature range from minus 40 to plus 100°C and spiral reinforced synthetic rubber hose to operate over temperature range from minus 40 and up to +120°C in hydraulic systems for use on Her Majesty's [HM] Surface Ships, Submarines and appropriate Shore Establishment application. The size ranges of these hoses are based upon ISO 1436 and ISO 3862.

The tests specified within this Standard reflect the most stringent performance requirements expected in service. The hose assemblies purchased to this Def Stan however may be used for less stringent applications. Alternative requirements will be specified within the Contract.

Hose Types

Type 1 - Hose with one layer of wire braid reinforcement -40°C to +100°C (Equivalent to ISO 1436 1ST).

Type 2 - Hose with two layers of wire braid reinforcement -40°C to +100°C (Equivalent to ISO 1436 2ST).

Type 3 - Hose with four or more spiral wound wire reinforcements -40°C to +100° (Equivalent to ISO 3862 4SP)

Type 4- Hose with four or more spiral wound wire reinforcements for Temperature Range -40°C to +100°C (Equivalent to ISO 3862 R12).
