This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial type aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under pressure of 1800 to 2100 psig at 70 F. Upon opening the valve, oxygen will be permitted to discharge from the storage cylinder to the valve outlet and thence to other components of the oxygen system. It shall also be possible to recharge the cylinder through the valve.
This SAE Recommended Practice describes basic instrumentation system requirements for use in only those SAE laboratory impact tests which reference this report. Individual SAE laboratory impact test procedures may indicate required deviations from the specifications given here. The items to be measured in laboratory impact tests may include any or all of the following: accelerations, velocities, penetrations, distances, forces, and event timing.
Many of the lighting devices on motor vehicles are legally required and arc essential to safe operation on the highway. To maintain performance, it is important that the bulb and sealed unit types employed he readily available, when needed, throughout the country in normal service channels. Therefore, this SAE Standard lists an assortment of current popular types, together with their characteristics, which are recommended for use wherever practicable. It is recognized that because of constantly changing and improving technology, the list may be incomplete. Also, instances may arise in the design of some devices which require the employment of other types while achieving the desired performance.
