Appliance classes (also known as protection classes) specify measures to prevent dangerous contact voltages on unenergized parts, such as the metallic casing, of an electronic device. In the electrical appliance manufacturing industry, the following appliance classes are defined in IEC 61140 and used to differentiate between the protective ...
IEC 60211 Maximum demand indicators, Class 1.0; IEC 60212 Standard conditions for use prior to and during the testing of solid electrical insulating materials; IEC 60214 Tap-changers; IEC 60215 Safety requirements for radio transmitting equipment; IEC 60216 Electrical insulating materials – Thermal endurance properties
IPC standards are used by the electronics manufacturing industry. IPC-A-610, [4] Acceptability of Electronic Assemblies, is used worldwide by original equipment manufacturers and EMS companies. There are more than 3600 trainers worldwide who are certified to train and test on the standard. Standards are created by committees of industry volunteers.
The different classes are defined by NEMA, [1] Underwriters Laboratories (UL), [2] and IEC standards. For complete electrically operated appliances, the "insulation system" is the overall design of electrical insulation of the energized components to ensure correct function of the device and protection of the user from electric shock .
[12] [13] The standards mandated by the IPC differ based on a product's classification under one of three defined product classes. [12] [13] These classes are: Class 1: general electronic products, for objects where the functionality of the final product is the major requirement.
Hence a wide range of solder alloys exist, and only major ones are listed below. Since early 2000s the use of lead in solder alloys is discouraged by several governmental guidelines in the European Union, Japan and other countries, [1] such as Restriction of Hazardous Substances Directive and Waste Electrical and Electronic Equipment Directive.
The standard has withdrawn in favor of international standards IEC 60603-2 and EN 60603-2. DIN 41612 connectors are used in Pancon , [ 1 ] STEbus , [ 2 ] Futurebus , VMEbus , Multibus II, NuBus , Acorn Archimedes expansion bus, [ 3 ] VXI Bus, [ 4 ] eurocard TRAM motherboards, [ 5 ] and Europe Card Bus , all of which typically use male DIN 41612 ...
MIL-DTL-5015 is a United States Military Standard which covers heavy-duty circular electrical connectors with soldered or crimped contacts. [1] They are used for both digital and analog signals, as well as power distribution, and are common in various fields, including defense, aerospace, and industrial machinery. [2]
