ITC Services focuses on ensuring compliance with electromagnetic compatibility (EMC) standards for businesses worldwide. They specialize in measuring RF emissions from cables, device under test and conducting immunity tests. There are numerous EMC standards that cater for almost any type of device. These product EMC standards provides limits and test levels, but in general, they refer back to a series of basic EMC standards containing the measurement methods.

Product EMC standards include Industrial, Scientific and medical (ISM) equipment (CISPR 11 / SANS 211), Broadcast receivers and associated equipment (CISPR 13 / SANS 213), Household appliances, electric tools and similar apparatus (CISPR 14 / SANS 214), Lighting equipment (CISPR 15 / SANS 215), Information technology equipment (ITE) (CISPR 22 / SANS 222), Equipment for measurement, control and laboratory use (SANS 61326-1 / IEC 61326-1), Detonators (SANS 1717-1), EMC for Radio equipment and services (ETSI EN 301 489-1), EMC and ERM for short range devices (ETSI EN 300 220-1), Essential requirements for GSM band 900 & 1800 (ETSI EN 301 511), IMT cellular networks essential requirements (ETSI EN 301 908), and Wide band transmission systems operating in the 2.4GHz ISM band (ETSI EN 300 328).

While basic EMC standards include Electro Static discharge immunity (IEC 61000-4-2 / SANS 61000-4-2), Radiated immunity (IEC 61000-4-3 / SANS 61000-4-3), Fast transient burst immunity (IEC 61000-4-4 / SANS 61000-4-4), Surge immunity (IEC 61000-4-5 / SANS 61000-4-5), Conducted immunity (IEC 61000-4-6 / SANS 61000-4-6), Power frequency magnetic immunity (IEC 61000-4-8 / SANS 61000-4-8), Pulse magnetic field immunity (IEC 61000-4-9 / SANS 61000-4-9), Voltage dips, short interruptions and voltage variations immunity test (IEC 61000-4-11 / SANS 61000-4-11).

The EMC Directive (2004/108/EC) sets the essential protection requirements for electrical and electronic equipment.

The EMC Directive limits electromagnetic emissions of equipment in order to ensure that, when used as intended, this equipment does not disturb radio and telecommunication and other related equipment. The Directive governs the immunity of these types of equipment to interference and seeks to ensure that this equipment is not disturbed by radio emissions when used as described.

In order to market your electrical device(s) within any of the member states of the European Union, your product must comply with harmonized standards (such as EN 55022 for IT Equipment). For the South African market we use the SANS equivalent specifications in place of EN 55022 / CISPR 22 and IEC.
