gaseous fuels), 93/42/EEC (medical devices) and 73/23/EEC (electrical equipment designed for use within certain voltage limits). The size of the CE marking must be at least 5 mm, if enlarged its proportions have to be kept. If the appearance and workmanship of a product do not allow for the CE marking to be affixed on the product itself, the marking has to be affixed to its packaging or accompanying documents. If a norm requires the involvement of a Notified Body in the conformity assessment procedure, depending on the legislation, an identification number may need to be put behind the CE logo. This is done under the responsibility of the Notified Body. Misuse The European Commission is aware that CE markings, like other certifications marks, are misused. CE marking is sometimes affixed to products that do not fulfill the legal requirements and conditions, or it is affixed to products for which it is not required. In one case it was reported that "Chinese manufacturers were submitting well-engineered electrical products to obtain conformity testing reports, but then removing non-essential components in production to reduce costs". A test of 27 electrical chargers with UK sockets in 2008 found that all the eight legitimately branded ones with a reputable name met safety standards, but none of those unbranded or with minor names did, despite bearing the mark; non-compliant devices were actually potentially unreliable and dangerous, presenting electrical and fire hazards. There are also cases in which the product complies with the applicable requirements, but the form, dimensions, or proportions of the mark itself are not as specified in the legislation. "China Export" In 2008, a logo very similar to CE marking was alleged to exist and to stand for China Export because some Chinese manufacturers apply it to their products. However, the European Commission says that this is a misconception. The matter was raised at the European Parliament in 2008. The Commission responded that it was unaware of the existence of any "Chinese Export" mark and that, in its view, the misunderstanding had arisen because a producer had failed to respect the precise dimensions and proportions of the mark as prescribed in the legislation. The commission was also aware of fraudulent misuse of the mark on products that did not comply with the standards, but that this is a separate issue. It had initiated the procedure to register CE marking as a Community collective
