IEC 60071-5:2014 provides guidance on the procedures for insulation co-ordination of high-voltage direct current (HVDC) converter stations, without prescribing standardized insulation levels. This standard applies only for HVDC applications in high-voltage a.c. power systems and not for industrial conversion equipment. Principles and guidance given are for insulation co-ordination purposes only.…

IEC 60684-3-284:2014 gives the requirements for heat-shrinkable sleevings for oil barrier, medium voltage cable jointing and termination applications, with nominal shrink ratios of up to 3:1. These sleevings have been found suitable for use up to temperatures of 80 °C. Included are Type A: polyolefin based and Type B: fluoropolymer based, enhanced oil resistance. These sleevings are normally…

IEC 60684-3-285:2014 gives the requirements for heat-shrinkable sleeving for medium voltage joint insulation, with a range of shrink ratios. This sleeving has been found suitable up to temperatures of 100 °C. These sleevings are normally supplied in colour, red or brown. Since this type of sleevings covers a significantly large range of sizes and wall thicknesses, the actual size will be agreed…

IEC 60115-8-1:2014 is applicable to the drafting of detail specifications for fixed surface mount (SMD) low-power film resistors in rectangular chip shape (styles RR) or in cylindrical MELF shape (styles RC) classified to level G, which is defined in IEC 60115-8:2009, 1.5 for general electronic equipment, typically operated under benign or moderate environmental conditions, where the major…

1 Scope 1.1 This Standard describes zinc-coated steel wire strand suitable for use as guys, suspension strand, span wires, and overhead ground wire strand. Overhead ground wire strand for electric power transmission is produced free of wire joints. Included are requirements for Grades 800, 1100, 1300, and 1500 (110, 160, 180, and 220). Zinc coatings for all grades include hot-dip Class A and…

1 Scope 1.1 This Standard applies to portable type gas water heaters (herein after referred to as appliance or water heater) for use with propane, butane, or liquefied petroleum gases and mixtures thereof having: a) a regulated pressure; b) a non-regulated pressure. 1.2 Portable type water heaters and components employing materials or having forms of construction differing from those…

1 Scope 1.1 This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for plant-applied fusion bond epoxy (FBE) coating applied externally to bare steel pipe. The coated pipe is intended primarily for buried or submerged service for oil or gas pipeline systems. 1.2 This Standard covers the following coating systems: (a) System 1A…

1 Scope 1.1 This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for coatings applied externally to steel piping in the field or a shop. Coated piping addressed by this Standard is intended primarily for buried or submerged service in oil or gas pipeline systems. 1.2 This Standard covers the following coating systems: a)…
