Off spec意思

"Off spec" is a term commonly used in various industries, particularly in manufacturing, quality control, and engineering, to indicate that a product, material, or component does not meet the specifications or standards set for it. The term "spec" is short for "specification," which refers to the detailed technical requirements that a product or service must meet.

When something is "off spec," it means that it falls outside the acceptable range of characteristics, dimensions, performance criteria, or other parameters that are defined in the specifications. This can happen due to various reasons, such as manufacturing errors, incorrect ingredients, deviations in the production process, or failure to meet quality standards.

In the context of manufacturing, for example, off-spec products may not be fit for their intended purpose and may need to be reworked, discarded, or sold at a lower price if they can be used for other purposes. In the chemical industry, off-spec materials may not meet the required purity levels or have an incorrect concentration of active ingredients.

The term can also be used in more general contexts, such as in project management or software development, to indicate that a deliverable does not meet the specified requirements or design criteria.

It's important to note that being off-spec is generally considered negative, as it indicates a failure to meet the expected standards. However, in some cases, off-spec products may still be usable or marketable if they can be used for alternative purposes or if they only slightly deviate from the specifications.
