Date: 1979-01-01
Description: SCOPE AND FIELD OF APPLICATION This standard specifies torque-tension test requirements for prevailing-torque type steel metric hex nuts and hex flange nuts, - with hex nut nominal thread diameters M6 thru M24 - with hex flange nut nominal thread diameters M6 thru M20 - of property classes 9 and 10 - with mechanical and performance properties in conformance with ANSI B18.16.1M-1979.
AWWA M49 - BUTTERFLY VALVES: TORQUE, HEAD LOSS, AND CAVITATION ANALYSIS - SECOND EDITION Organization: AWWA
Date: 2012-01-01
Description: Actual flow, cavitation, or torque coefficients for a particular manufacturer's valve should be used in calculations for a specific valve and application to obtain the highest calculation accuracy The history of this manual is related to that of American National Standards Institute ANSI/AWWA C504, Standard for Rubber-Seated Butterfly Valves. Until the 1994 edition, ANSI/AWWA C504 included Appendix A, which described a recommended method of calculating torques for butterfly valves.
NAVISTAR - MPAPS S-EM-56.101-GS/PL - PREVAILING TORQUE HEX NUTS – ALL METAL – METRIC SERIES (NOUN CODE 5780) Organization: NAVISTAR
Date: 2015-06-01
Description: This specification contains elements of the following standards: American National Standards Institute: 18.16.3M International Organization for Standardization: ISO 2320, 7042, 7719 Prevailing torque type is a nut which is frictionally resistant to rotation due to a self-contained prevailing torque feature, and not because of a compressive load developed against the bearing surface of the nut. Prevailing torque is the torque necessary to rotate the nut on its mating externally threaded component, with the torque being measured while the nut is in motion, and with no axial load in the mating component.
NAVISTAR - MPAPS S-EM-58.101-GS/PL - PREVAILING TORQUE HEX FLANGE NUTS – ALL METAL – METRIC SERIES (NOUN CODE 5780) Organization: NAVISTAR
Date: 2015-06-01
Description: GENERAL: This specification is based on and contains elements of the following standards: American National Standard: ANSI B-18.16.1M, B-18.16.2M, B-18.16.3M International Organization for Standardization: ISO 7044 General specifications, mechanical and performance requirement, and test requirements for prevailing torque nuts outlined in MPAPS S-EM-56.101-GS/PL are also applicable to this standard.
ISA - 96.02.01 - GUIDELINES FOR THE SPECIFICATION OF ELECTRIC VALVE ACTUATORS Organization: ISA
Date: 2016-03-17
Description: This standard is not intended to address the range of compact, light duty low torque electric actuators typically rated for less than 5.65 Nm (50 in-lbs), and it is not intended for electrically powered actuators that use hydraulic fluid for power transmission (refer to ANSI/ISA-96.06.01).
ASME B1.12 - CLASS 5 INTERFERENCE-FIT THREAD Organization: ASME
Date: 1987-01-01
Description: It is intended that designs conforming with this Standard will provide adequate torque conditions which fall within the limits shown in Table 8. The minimum torques are intended to be sufficient to insure that externally threaded members will not loosen in service; the maximum torques establish a ceiling below which seizing, galling, or torsional failure of the externally threaded components is reduced.
AGMA 932 - RATING THE PITTING RESISTANCE AND BENDING STRENGTH OF HYPOID GEARS Organization: AGMA
Date: 2005-01-19
Description: Lengthwise sliding in hypoids reduces their efficiency. Torque losses between driving pinion and gear range from 2 to 15 percent depending on the offset, spiral angles, velocity and lubrication.
ASABE S604 - SAFETY FOR POWER TAKE-OFF (PTO), PTO DRIVE SHAFTS, AND POWER INPUT CONNECTION (PIC) FOR AGRICULTURAL FIELD EQUIPMENT Organization: ASABE
Date: 2014-09-01
Description: It is not applicable to PTO drive shafts guarded by location or to the mechanical characteristics of overrun devices and torque limiters, nor are environmental aspects considered; neither is it applicable to PTO drive shafts and their guards manufactured before the date of its publication, neither is it applicable to service parts for agricultural equipment for field or stationary operation manufactured before the date of this publication.
GMNA - 9985473 - PREAPPLIED THREAD SEALER - REVISION C Organization: GMNA
Date: 2005-04-01
Description: For more information see SAE J476 or ANSI B1.20.3. Each sealant has its own lubricity (k) factor reducing torque coefficient of threaded assemblies resulting in lower applied on-torques to achieve sealing or clamp load.
NAVISTAR - MPAPS S-F-16.101-GS/PL - HARDENED WASHERS – ENGLISH SERIES (NOUN CODE 9720) Organization: NAVISTAR
Date: 2015-06-01
Description: These washers are intended for use in high clamping loads, to minimize embedding, and to aid torquing.
SAE MA4535 - WRENCHES, BOX AND OPEN END COMBINATION TWELVE POINT, HIGH STRENGTH, THIN WALL, METRIC Organization: SAE
Date: 2013-02-01
Description: This SAE Metric Aerospace Standard (MA) provides dimensional, performance, testing and other requirements for high strength, thin wall, double head box and combination wrenches which possess an internal wrenching design so configured that, when mated with hexagon (6 point) fasteners, they shall transmit torque to the fastener without bearing on the apex of the fastener's wrenching points.
SAE MA4534 - SOCKET WRENCHES, HAND (METRIC) Organization: SAE
Date: 2013-02-01
Description: This SAE Aerospace Standard covers high strength commercial sockets and universal sockets which possess the strength, clearances, and internal wrenching design so configured that, when mated with hexagon (6 point) fasteners, they shall transmit torque to the fastener without bearing on the outer 5% of the fastener's wrenching points.
GMNA - 9985490 - THREAD SEALER, PREAPPLIED FOR VEHICLE APPLICATIONS - REVISION C Organization: GMNA
Date: 2004-12-01
Description: For more information see SAE J476 or ANSI B1.20.3. Each sealant has its own lubricity (k) factor reducing torque coefficient of threaded assemblies resulting in lower applied on-torques to achieve sealing or clamp load.
SAE J499 - PARALLEL SIDE SPLINES FOR SOFT BROACHED HOLES IN FITTINGS Organization: SAE
Date: 2014-06-01
Description: The method and amount of "breaking" sharp corners and edges also depend upon the conditions and requirements of each application. The formula for theoretical torque capacity (pressure on sides of spline) in inch-pounds per inch of bearing length (L) and at 1000 psi pressure is: The tolerances allowed are for good construction and may be readily maintained by usual broaching methods.
