IECEE

The IECEE is the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components being a body of the International Electrotechnical Commission. The IEC uses the name IECEE for the IEC System for Conformity Testing and Certification of Electrotechnical Equipment and Components that is better known as the CB System

The predecessor of IECEE was a European body founded under the name of Commission internationale de réglementation en vue de l'approbation de l'équipement électrique (International commission on rules for the approval of electrical equipment) known as CEE. Historically this certification process goes back to 1929 based on an initiative by the German VDE (Verband der Elektrotechnik, Elektronik und Informationstechnik).

CEE also devised and published standards for electrical equipment, most of which have been superseded by IEC standards.

CB Scheme

The IEC CB Scheme is multilateral agreement to allow international certification of electrical and electronic products so that a single certification allows worldwide market access.

C

C is the third letter in the English alphabet and a letter of the alphabets of many other writing systems which inherited it from the Latin alphabet. It is also the third letter of the ISO basic Latin alphabet. It is named cee (pronounced /ˈsiː/) in English.

History

"C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name gimel. Another possibility is that it depicted a camel, the Semitic name for which was gamal. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)".

In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek 'Γ' (Gamma) was adopted into the Etruscan alphabet to represent /k/. Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etruscan. In Latin it eventually took the 'c' form in Classical Latin. In the earliest Latin inscriptions, the letters 'c k q' were used to represent the sounds /k/ and /ɡ/ (which were not differentiated in writing). Of these, 'q' was used to represent /k/ or /ɡ/ before a rounded vowel, 'k' before 'a', and 'c' elsewhere. During the 3rd century BC, a modified character was introduced for /ɡ/, and 'c' itself was retained for /k/. The use of 'c' (and its variant 'g') replaced most usages of 'k' and 'q'. Hence, in the classical period and after, 'g' was treated as the equivalent of Greek gamma, and 'c' as the equivalent of kappa; this shows in the romanization of Greek words, as in 'KAΔMOΣ', 'KYPOΣ', and 'ΦΩKIΣ' came into Latin as 'cadmvs', 'cyrvs' and 'phocis', respectively.
