Durability

Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime.[1]:5 Several units may be used to measure the durability of a product according to its field of application, such as years of life, hours of use, and operational cycles.[2] In economics, good with a long usable life are referred to as durable goods.

Requirements for product durability[edit]

Product durability is predicated by good reparability and regenerability in conjunction with maintenance.[3] Every durable product must be capable of adapting to technical, technological and design developments.[3] This must be accompanied by a willingness on the part of consumers to forego having the "very latest" version of a product.

Durability as a characteristic relating to the quality of goods that can be demanded by consumers was not clearly established until an amendment of the law[which?] relating to the quality standards for supplied goods in 1994.[4]

Product life spans and sustainable consumption[edit]

The lifespan of household goods is a significant factor in sustainable consumption.[5] Longer product life spans can contribute to eco-efficiency and sufficiency, thus slowing consumption in order to progress towards a sustainable level of consumption.[6] Cooper (2005) proposed a model to demonstrate the crucial role of product life spans to sustainable production and consumption.[6]

Types of durability[edit]

Durability can encompass several specific physical properties of designed products, including:
