BS 2M 51:1989 download free.Classification for Pressure and temperature for fluid systems and components.
0 Introduction
Aerospace fluid systems and corn ponents are generally designed and marked for a specific fluid pressure and temperature type. The operating Iressures listed are selected from ISO 2944 as far as practical.
1 Scope and field of application
BS 2M 51 establishes the temperature types and pressure classes that are commonly used in aerospace fluid systems.
2 Reference
ISO 2944, Fluid power systems and components — Nominal pressures.
3 Temperature classification
System operating temperature ranges shall be classified as given in Table 1.
4 Nominal pressure classification
Nominal pressures shall be classified as given inb Table 2.
