The Martindale is a unit for quantifying the abrasion resistance of textiles, especially when used for upholstery. The Martindale method, also known as the Martindale rub test, simulates natural wear of a seat cover, where the textile sample is rubbed against a standard abrasive surface with a specified force. The test equipment works in intervals of 5000 cycles, totalling the ''wear number'' (unit: Martindale) of abrasion cycles that leads to the material being worn to a specified degree. The higher the value, the more resistant the material is to abrasion. The national German textile institute specifies a minimum requirement for various applications, and here are some examples: Consoles for use by police or emergency services may require values of 200,000 to 500,000. In the US, the Wyzenbeek test is often used instead of the Martindale. == External links == * ''(Abrasion Resistance by the Martindale Method ASTM D4966-98 Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method) )'' (PDF) * (Martindale Rub Test ) by Kothea Limited * (Table of contents of DIN EN ISO 12947-1:2007-04 by Beuth-Verlag ) 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「Martindale (unit)」の詳細全文を読む スポンサード リンク
