What is Mil specification?What is the military standard?The terms military standards and military norms can be used in exchange.They can be abbreviated as mil std, MIL-STD and mil specifications, respectively.Military Standards traditionally apply to anything of military orders, which gradually penetrate into many areas of government procurement and other products manufactured by defense contractors.
If it is expropriated by the Ministry of Defense, it must comply with military specifications, I .E.e.Military standards.If your drawings or test documents say that mil specification 1629 must be met, then it must meet military standard 1629, abbreviated as MIL-STD-1629 or mil std 1629.Many military standards are earlier than ISO and ANSI standards in the same region, and military standards such as documents and drawings have gradually been incorporated or replaced by groups such as ANSI International and international standards organizations.
Although common industry standards are gaining popularity, military standards in marking items and packaging remain primarily military specifications.MIL-STD-100 is the military standard for engineering drawing practice.MIL-STD-103 a standard abbreviation for electrical and electronic terms is given.
MIL-STD-106 mathematical symbols and symbols related to physical science are listed.MIL-STD-12 abbreviations used in military and defense department drawings, specifications and technical documents are given.MIL-STD-8 is the old military standard for size and tolerance.
MIL-STD-8 replaced by ASME/ANSI standard y14.5.MIL-STD-38784 is a military standard and style guide for technical manuals.This is different from a style guide like The Associated Press style guide.
MIL-STD-973 is the DoD standard for configuration management.Configuration management or CM refers to the process of managing changes in everything from drawings to technical specification files to test programs.Documents have unique identifiers assigned to them.
Review and approve changes to documents.
The updated document is reviewed before it is officially released with a new revised letter and release date attached so that readers can know the existence of the earlier version and when the version they are reading is released.For the drawings of many newer military and military contractors, the ISO standard for configuration management is specified, not the military standard.MIL-STD-1815 is a military standard for ADA programming languages.
MIL-STD-1840 is the military standard for automatic exchange of technical information.MIL-STD-2096 the data requirements of the micro circuit are given.Most of the other military standards for information technology and programming languages are now from IEEE and ISO.
Circuit cards and test equipment are now programmed in general technical languages, although CATLAS can be used to verify an automated test set for the correct configuration of PCB assembly.MIL-STD-101 The color code of the pipe and compressed gas cylinder is given.MIL-STD-102mm is standard defenseIdentification code for friction bearings.
MIL-STD-1247 is the standard for marking hoses and pipes according to their functions and the hazards they pose.MIL-STD-1285 is the standard for marking electrical and electronic parts.MIL-STD-1189 the bar code symbol standard of the Ministry of Defense is given.
MIL-STD-129 is the marking standard for shipment and storage of items.Military StandardsSTD-130 is the standard for identification marks placed in the United StatesS.Military property.MIL-STD-1458 is the standard for marking and labeling radioactive materials.
MIL-STD-190 is the standard for marking rubber products.MIL-STD-450 is the standard for marking marks of contaminated or hazardous areas.This is similar to ANSI z535.MIL-STD-456 is the standard of the date code used on the electronic part, indicating when the part is manufactured.
MIL-STD-595 is the color standard used in government procurement.The Federal Standard 595C replaces this military standard.MIL-STD-721 gives definitions of reliability and durability terms used in other DoD standards.
MIL-STD-2074 fault classification of reliability test is given.MIL-STD-470 the criteria for maintenance procedures are outlined.Maintenance is defined as the ability of the design to divide faults, for example, the circuit is short-circuited or has bullet holes through, the ability to close the damaged area, switch back to the circuit and continue to operate.
The device is easy to maintain as instead of having to turn it off, you take it apart all the way to fix it.MIL-STD-1390 describes the concept of a repair level and how to perform a repair level analysis or LORA.In the Repair Analysis level, perform a logical analysis to determine if it is best to fix a project, replace it, or throw it away.
LORA decisions must take into account the cost of each result and the performance of the part.For example, it may be cheap to choose to fix something and put it back on the plane, but it may not be safe.MIL-STD-2084 is the maintenance standard for avionics systems and electrical subsystems (such as PCB components and their shells) when used on aircraft.
MIL-STD-1629 the process of performing fault patterns, impacts, and critical analysis is given.This can also be called FMEAC analysis.This analysis is the process of determining the root cause of the failure or determining the way the design may fail in order to improve the design.For example, if the helicopter falls from the air, if one of the two wires on the rotor is cut off, the solution may be to add another or two wires.
MIL-STD-756 is the standard for system reliability modeling and forecasting.The estimated failure rate of the product can be used to determine whether it is reliable enough for military use before mechanical manufacturing and testing, and to test the reliability and safety of the design.The PCB assembly will be tested to determine if it can still pass the data to the pilot if a wire or circuit card burns out.
MIL-STD-2073 is the military packaging standard of the Ministry of Defense.MIL-STD-648 the design standards for military containers are given.MIL-STD-649 is the standard for preparing aluminum and magnesium products for shipment and storage.
MIL-STD-726 is the standard to outline the packaging requirements.MIL-STD-726 has been replaced by MILSTD-2073-2.MIL-STD-731 the quality of the wood components used in transport, such as the wood used to manufacture pallets and crates, is outlined.
MIL-STD-3010 described test procedures for packaging materials to verify that they can process the rough treatment they will see on site before military components are packed and shipped.MIL-STD-1313 is the standard for electronic technical terms and definitions.MIL-STD-1332 the definition of tactical terms is given.
MIL-STD-1241 the optical terms and definitions used in military standards are listed.MIL-STD-1309 the definition of the terms used in all other military standards for testing, measurement and diagnosis is given.MIL-STD-280 the definition used to explain the project level is given.
MIL-STD-280 also sets the standard for the exchange of items, a technical term used to remove and replace one part with another with the \"plug and play\" function.For example, Level 0 usually refers to top-level parts, while Level 1 refers to items assembled into the design.If Level 0 is a helicopter, Level 1 can refer to the rotor assembly or motor assembly.
The second level will consist of auto parts and rotor parts.For PCB components, the PCB housing will be level 1, while the final PCB assembly will be level 0
