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 There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. [ 2 ]
A car is a durable good. The gasoline that powers it is a non-durable (or consumable) good.. In economics, a durable good or a hard good or consumer durable is a good that does not quickly wear out or, more specifically, one that yields utility over time rather than being completely consumed in one use.
A product's durability for example, can seldom be observed directly; it usually must be inferred from various tangible and intangible aspects of the product. In such circumstances, images, advertising and brand names -inferences about quality rather than the reality itself- can be critical.
Generally, actual product lifetimes refer to the actual time that a product exists in a particular state. [1] In contrast, expected product lifetimes refer to users' expectations for the lifetime of a product. [10] Additionally, actual and expected product lifetimes are influenced by durability and longevity; these concepts are briefly outlined ...
Atomicity, consistency, isolation (sometimes integrity), durability is a transaction metric. When dealing with safety-critical systems, the acronym reliability, availability, maintainability and safety is frequently used. [citation needed] Dependability is an aggregate of availability, reliability, safety, integrity and maintainability.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The ultimate examples of such design are single-use versions of traditionally durable goods, such as disposable cameras, where the customer must purchase entire new products after using them just once. Such products are often designed to be impossible to service; for example, a cheap throwaway digital watch may have a case which is sealed in ...
It also describes product manufactured for non-aesthetic purposes, where fitness for purpose is the primary criterion. [1] [2] Engineering of high-performance fabrics presents a unique set of challenges. [1] [3] The fitness for purpose of textile products is an important consideration for both producers and buyers.
