What term is used for a product that does not meet specified requirements?

The term that accurately describes a product that does not meet specified requirements is "Non conforming Product." This terminology is rooted in quality management and compliance standards, signifying that the product falls short of meeting predetermined criteria or specifications, which could include dimensions, performance characteristics, or other quality standards.

The use of "Non conforming Product" is essential in quality control processes, as it allows organizations to identify and address issues associated with products that deviate from their expected performance or quality. This concept is critical in manufacturing and industry, where maintaining product quality is paramount for customer satisfaction and regulatory compliance.

Other terms like "Out of Specification," "Defective Product," and "Substandard Product" might seem similar but can imply slightly different issues. "Out of Specification" is often used in specific contexts to refer to testing results that exceed acceptable limits. "Defective Product" typically refers to a product that has a flaw or fault making it unsafe or unusable. Conversely, "Substandard Product" may indicate a general failure to meet certain quality benchmarks but is less specific than nonconformance, which is demonstrated through established protocols and standards. Thus, the precision of the term "Non conforming Product" makes it the most appropriate choice in this context.
