Measurements are made over the frequency range of 10 Hz to 400kHz. The measurements are relatively simple requiring various faces of the product to be tested. The limit and test distance varies depending on the potential exposure a human operator might experience. For example, appliances where a person might be in direct contact such as a electric blanket, dental hygiene appliances, body worn vacuum cleaners are required to be tested at 0 cm test distance. Products where an operator is some distance away and not in direct contact such as battery chargers, deep fat fryers, floor polishers, food processors, ice-cream makers, vacuum cleaners, and toasters are all tested at 50 cm. An intermediate distance of 30 cm is used for handheld tools, induction hobs, hotplates, microwave, standard ovens, refrigeration appliances, etc.

Other devices not described are covered by the default clause "Appliances not mentioned require a distance determined by the Operator distance".

D.L.S. has the capability to assist all appliance manufactures with this special offer. For manufacturers having many different physically large products, arrangements are being made to perform on site-testing.
