Glossary of Terms

  EMC (ElectroMagnetic Compatibility) - the study of the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (Electromagnetic interference, or EMI) may induce.

With reference to low voltage power supplies, compliance with a recognised EMC standards is not only a legal requirement, but ensures that the equipment is neither susceptible to interference from surrounding electronic devices nor causes interference to the operation of other electronic devices in the surrounding area.

Products manufactured by Tactical have been designed to comply with not only industrial (lowest) Australian & NZ EMC standards, but the extremely stringent domestic, scientific and medical standards - making them suitable for installation and operation in homes, laboratories and hospitals.

  EMI (ElectroMagnetic Interference) - also known as RFI (Radio Frequency Interference) at higher frequencies - is disturbance that affects the operation of electronic devices due to either electromagnetic induction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the device. These effects can range from a simple degradation of data to a total loss of data.

EMI can be intentionally used for radio jamming, as in some forms of electronic warfare, or can occur unintentionally as the result of spurious emissions from poorly designed or low quality electronic equipment. It frequently affects mobile phones , AM & FM radio and television reception and the operation of medical monitoring equipment.

As outlined in EMC above, Tactical products have been designed to comply with the highest EMC Standards.

  NATA - (National Association of Testing Authorities) is the authority in Australia responsible for the accreditation of laboratories, inspection bodies, calibration services, producers of certified reference materials and proficiency testing scheme providers throughout Australia. It is also Australia's compliance monitoring authority for the OECD Principles of GLP.

NATA provides independent assurance of technical competence through a proven network of best practice industry experts for customers who require confidence in the delivery of their products and services. NATA formally recognises that these facilities produce reliable technical results which make the world a safer and more certain place. NATA's work increases community confidence and trust in a facility's services, mitigates risk, improves tendering success and facilitates trade.

NATA is a not-for-profit company operating as an association owned and governed by its members and representatives from industry, government and professional bodies. The Australian Government uses NATA accredited facilities wherever possible and encourages state and territory governments and other instrumentalities to do likewise.

NATA employs around 175 staff in Sydney (head office), Melbourne, Brisbane, Adelaide and Perth. It is supported by some 3000 volunteer technical experts who assist with NATA's various technical committees and the evaluation of facilities.

  Standards Australia - Standards Australia is an independent, not-for-profit organisation, recognised by the Australian Government as the peak non-government Standards body in Australia. Standards Australia develops internationally aligned Australian Standards® that deliver Net Benefit to Australia and is the Australian member of ISO and IEC.  Website:
