loadrated

Loadrated is a term used in engineering and product documentation to describe a component or device that has been tested and assigned a maximum load it can safely bear under defined conditions. In some texts, the term appears as load-rated or load rating; elsewhere it is used informally to indicate that a part is capable of supporting a specified load.

The load rating (or load-rated status) is typically determined through static and dynamic testing, material property evaluation, and consideration of additional factors such as fatigue, temperature, and duty cycle. The rating may be expressed as a maximum static load, a safe working load, or a safety factor applied to expected service loads.

Relation to standards: The precise terminology varies by industry and region. Many applications use terms such as safe working load (SWL) or working load limit (WLL), and these are defined by standards from bodies such as ISO, ASTM, or EN. The informal term "loadrated" is not universally standardized and should be accompanied by explicit test methods and numerical values.

In practice, when selecting a load-rated component, buyers should review the stated load value, the applicable standards, installation and service conditions, and any de-rating factors. The terminology can differ; documentation should clarify whether the rating is for static, dynamic, or fatigue loading.
