Product lifetime
Product lifetime or product lifespan is the time interval from when a product is sold to when it is discarded. Product lifetime is slightly different from service life because the latter considers only the effective time the product is used. It is also different from product economic life which refers to the point where maintaining a product is more expensive than replacing it; from product technical life which refers to the maximum period during which a product has the physical capacity to function; and from the functional life which is the time a product should last regardless of external intervention to increase its lifespan.
Throw-away society
The throw-away society is a generalised description of human social concept strongly influenced by consumerism, whereby the society tends to use items once only, from disposable packaging, and consumer products are not designed for reuse or lifetime use. The term describes a critical view of overconsumption and excessive production of short-lived or disposable items over durable goods that can be repaired, but at its origins, it was viewed as a positive attribute. In its 1 August 1955 issue, Life published an article titled "Throwaway Living".
Durabilité (produit)
La durabilité est la capacité d'un produit physique à rester fonctionnel, sans nécessiter de maintenance ou de réparation excessive, lorsqu'il est confronté aux défis d'un fonctionnement normal au cours de sa . Il existe plusieurs mesures de durabilité en cours d'utilisation, y compris la durée de vie, la durée d'utilisation et le nombre de cycles opérationnels. En économie, les biens à longue durée de vie sont appelés biens durables. La durabilité du produit est conditionnée par une bonne réparabilité et en conjonction avec la maintenance.
Service life
A product's service life is its period of use in service. Several related terms describe more precisely a product's life, from the point of manufacture, storage, and distribution, and eventual use. Service life has been defined as "a product's total life in use from the point of sale to the point of discard" and distinguished from replacement life, "the period after which the initial purchaser returns to the shop for a replacement".
