This document specifies the performance requirements for metal halide lamps for general lighting purposes. For some of the requirements given in this document, reference is made to "the relevant lamp data sheet". For some lamps, these data sheets are contained in this document....
5.1 As stated in Terminology B542, contact resistance is comprised of a constriction resistance and a film resistance. When present, the latter of these is usually much greater in value and dominates the contact resistance. For a given contact spot, when the film resistance is zero or negligible...

2.1 Procedure A covers the determination of the equation of the curve relating resistance and temperature where the curve approximates a parabola. This test method may be used for wire of any metal or alloy over the temperature interval appropriate to the material. 2.2 Procedure B covers the...
This specification establishes the requirements for mat, bright, and flow-brightened electrodeposited tin-lead alloy coatings on fabricated articles of iron, steel, copper, and copper alloys to protect them against corrosion, to improve and preserve solderability over long periods of storage, and...

This specification gives the requirements for copper-clad Invar material for use in the fabrication of metal-clad laminated sheets, used for printed boards. The use of copper-clad Invar material boards modifies some properties of the boards, for example thermal capacity and...
This part of IEC 60747 gives details for the following categories of metal-oxide semiconductor field-effect transistors (MOSFETs) with inverse diodes. - Type B depletion (normally on) type. - Type C enhancement (normally off) type. NOTE 1 MOSFETs for some applications may not have inverse...
1.1 This test method covers the direct measurement of the sheet resistance and its variation for all but the periphery (amounting to three probe separations) for circular conducting layers pertinent to silicon semiconductor technology. These layers may be fabricated on substrates of any...
