Durability can be defined "the ability of a product to perform its required function over a lengthy period under normal conditions of use without excessive expenditure on maintenance or repair". Several units may be used to measure the durability of a product according to its field of application such as years of existence, hours of use and operational cycles.
Product life spans and sustainable consumption The life span of household goods is significant for
sustainable consumption. The longer product life spans could contribute to eco-efficiency and sufficiency, thus slowing consumption in order to progress towards a sustainable consumption. Cooper (2005) proposed a model to demonstrate the crucial role of product life spans for sustainable production and consumption. Durability, as a characteristic relating to the quality of goods that can be demanded by consumers, was not clear until an amendment of the law in 1994 relating to the quality standards for supplied goods. The condition of the economy is one of the biggest factors as well as the philosophy of money. Consumers want to use their money effectively and essentially get what they paid for, and in the best-case scenario, get more than what they paid for. In the pursuit of durable goods through the lifespans of the products and consumption of those products money and price dictate two of the biggest factors other than supply and demand. Durable goods fall into this category, as ease of commerce and convenience are key factors in making it a good product to buy. == See also ==
