EN 13402 Size designation of clothes is a European standard for labelling clothes sizes. It is based on body dimensions, measured in centimetres. It replaces many older national dress-size systems in popular use before the year 2007. Acceptance of this form of standardisation varies from country to country. For example, the Spanish Ministry of Health and Consumer Affairs has commissioned a study to categorise female body types with a view to harmonising Spanish clothing sizes with EN-13402. Few other countries are known to have followed suit. ==Background== There are three approaches for size-labelling of clothes: ; Body dimensions: The label states the range of body measurements for which the product was designed. (For example: bike helmet label stating "head girth: 56–60 cm") ; Product dimensions: The label states characteristic dimensions of the product. (For example: jeans label stating inner leg length of the jeans in centimetres or inches (not inner leg measurement of the intended wearer)) ; Ad hoc size: The label states a size number or code with no obvious relationship to any measurement. (For example: Size 12, XL) Traditionally, clothes have been labelled using many different ad hoc size systems. This approach has led to a number of problems: * For many types of garments, size cannot be adequately described by a single number because a good fit requires a match between two (or sometimes three) independent body dimensions. This is a common issue in sizing jeans. * Ad hoc sizes have changed with time due to changing demographics and increasing rates of obesity. This is often portrayed in media as vanity sizing. * Scalar ad hoc sizes based on 1950s anthropometric studies are no longer adequate, as changes in nutrition and life style have shifted the distribution of body dimensions. * Mail order requires accurate methods for predicting the best-fitting size. * Country-specific and vendor-specific labels incur additional costs. Therefore, the European standards committee CEN/TC 248/WG 10 started in 1996 the process of designing a new modern system of labelling clothes sizes, resulting in the standard EN 13402 "Size designation of clothes". It is based on: * body-dimensions * the metric system (SI) * data from new anthropometric studies of the European population performed in the late 1990s * similar existing international standards (ISO 3635, etc.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EN 13402」の詳細全文を読む スポンサード リンク
