1.1 This specification establishes requirements and test methods for dimensions and tolerances of central-vacuum hose inlet valve sockets. 1.2 All notes and footnotes shall be considered as non-mandatory requirements of the specification. 1.3 This specification does not apply to inlet...

002600-000000-000000 1 Scope 1.1 These requirements cover valve equipment intended for installation in piping systems to supply water automatically to dry pipe, deluge, and pre-action sprinkler systems for fire-protection service. 1.2 Valves covered by these requirements may be a...

1.1 This specification covers the highest quality of round and shaped chromium-silicon and chromium-silicon-vanadium alloys of steel valve spring wire, uniform in quality and temper, intended for the manufacture of valve springs and other springs requiring high-fatigue properties when...

014860-000000-000000 1 Scope 1.1 This Standard covers quick opening devices intended for attachment to dry pipe valves to reduce the time delay in operation of the valve following opening of one or more sprinklers. The quick opening devices consist of accelerators and exhausters for...

This practice provides guidance in the selection of manual and power-actuated valve operators. The selection criteria for manual valve operators apply to handwheels and tee-wrenches. The selection criteria for power-actuated valve operators, on the other hand, apply to stem nut...

This SAE Aerospace Recommended Practice (ARP) applies to landing gear structures and mechanisms (excluding wheels, tires, and brakes and other landing gear systems) for all types and models of civil and military aircraft. All axles, wheel forks, links, arms, mechanical and gas/oil shock struts,...

This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's...

014680-000000-000000 1 Scope 1.1 These requirements cover direct-acting pressure-reducing and pressure- restricting valves intended to reduce the water pressure in standpipe systems or in the supply piping for sprinkler systems. These requirements also cover pressure- reducing valves...

This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under a nominal pressure of 12.76 MPa (1850 psig) at 21 °C (70 °F)....

1.1 This specification covers four different grades of round and shaped plain carbon and alloy steel spring wire, uniform in quality and temper, intended for the manufacture of mechanical springs that can withstand moderate fatigue stresses over some relatively low number of cycles. The quality...

5.1 This test method was developed to evaluate automotive lubricant's effect on controlling cam lobe wear for overhead valve-train equipped engines with sliding cam followers. Note 1: This test method may be used for engine oil specifications, such as Specification D4485, API 1509, SAE J183,...

The air cranking system components, which include the tank, valve, hose, and starter, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold...

1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in...

5.1 This practice is suitable for the removal of contaminants found on materials, parts, and components used in systems requiring a high level of cleanliness, such as oxygen. Parts shall have been precleaned to remove visible contaminants prior to using this procedure. Softgoods such as seals and...

5.1 This practice is suitable for the determination of extractable substances that may be found in materials used in systems or components requiring a high level of cleanliness, such as oxygen systems. Soft goods, such as seals and valve seats, may be tested as received. Gloves and wipes, or...

1.1 This test method is commonly referred to as the John Deere Cavitation Test.2 The test method defines a heavy-duty diesel engine to evaluate coolant protection as related to cylinder liner pitting caused by cavitation. 1.2 The values stated in SI units are to be regarded as the standard. The...

5.1 Excessive amounts of sodium can indicate the presence of materials that cause high wear of burner pumps and valves, and contribute to deposits of boiler heating surfaces.

1.1 This specification covers thermoplastic fluoropolymer-based materials, intended for use as an encapsulation material for downhole cables used during well completion by the petroleum and natural gas industries. 1.1.1 The fluoropolymer-based materials to be used for this purpose shall be virgin...
