IEC Standards

This section of IEC 60534 specifies the mandatory and supplementary markings required for control valves. Some mandatory markings may not be suitable for certain valve designs, and some supplementary markings might only be appropriate for specific types of control valves. It is recommended that all valve markings adhere to this standard as much as possible

This section of IEC 60534 outlines the requirements for the inspection and routine testing of control valves that are produced in accordance with the other sections of IEC 60534. It is applicable to valves with pressure ratings up to Class 2500, and the requirements for actuators are limited to pneumatic types. This standard is not

This section of IEC 60534 is applicable to all varieties of industrial-process control valves (hereafter referred to as control valves). It establishes a partial basic terminology list and offers guidance on utilizing the other sections of IEC 60534.

This section of IEC 60519 pertains to industrial high-frequency dielectric heating installations designed for thermal applications such as melting, drying, welding, insect extermination, and the bonding of partially or non-conductive materials like plastics, wood, rubber, textiles, glass, ceramics, paper, bamboo, and food products, all within normal and protective atmospheres, including the use of inert gases

This part of IEC 60519 applies to electroheat installations for remelting and, in some cases, refining processes of metals through direct resistance heating of a conductive slag. The particular requirements for the safety of persons in or around an electroslag remelting furnace are the object of this standard. The general requirements are included in IEC

This section of IEC 60519 is applicable to installations for induction and conduction heating of solids at low, mains, medium, and high frequencies (for conduction heating, use of direct current is also included); installations for induction melting, holding, and superheating liquid metal at low, mains, medium, and high frequencies; and those parts of the conveying

This section of IEC 60519 is applicable to indirect resistance heating equipment and direct resistance heating equipment specified in items a) and b) below, respectively, operating in voltage bands 1 and 2. The objective of this standard is to standardize safety requirements for both indirect and direct resistance heating equipment described below. a) Indirect Resistance
