Product testing, also called consumer testing or comparative testing, is a process of measuring the properties or performance of products. The theory is that since the advent of mass production manufacturers produce branded products which they assert and advertise to be identical within some technical standard. Product testing seeks to ensure that consumers can understand what products will do for them and which products are the best value. Product testing is a strategy to increase consumer protection by checking the claims made during marketing strategies such as advertising, which by their nature are in the interest of the entity distributing the service and not necessarily in the interest of the consumer. The advent of product testing was the beginning of the modern consumer movement. Product testing might be accomplished by a manufacturer, an independent laboratory, a government agency, etc. Often an existing formal test method is used as a basis for testing. Other times engineers develop methods of test which are suited to the specific purpose. Comparative testing subjects several replicate samples of similar products to identical test conditions. == Purposes == Product testing might have a variety of purposes, such as: * Determine if, or verify that, the requirements of a specification, regulation, or contract are met * Decide if a new product development program is on track: Demonstrate proof of concept * Provide standard data for other scientific, engineering, and quality assurance functions * Validate suitability for end-use * Provide a basis for technical communication * Provide a technical means of comparison of several options * Provide evidence in legal proceedings: product liability, patents, product claims, etc. * Help solve problems with current product * Help identify potential cost savings in products Product tests can be used for: * Subjecting products to stresses and dynamics expected in use * Reproducing the types of damage to products found from consumer usage * Controlling the uniformity of production of products or components 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「Product testing」の詳細全文を読む スポンサード リンク
