normy

Normy (from norma) is a Polish term used to refer to rules, standards, and conventions across different domains. The word can denote socially accepted behavior, technical specifications, or mathematical measures of size and length. Its precise meaning depends on the field in which it is used.

In sociology and everyday life, normy describe social norms—unwritten rules that guide behavior, communication, and expectations within a group. They are reinforced by social sanctions, imitation, and education, and may vary across cultures, subcultures, and situations. Norms can be prescriptive (what one should do) or proscriptive (what one should not do).

In engineering, manufacturing, and public standards, normy are formal normative documents that specify requirements, test methods, and quality criteria for products and processes. They are issued by standardization bodies such as ISO, EN, or national committees. Compliance with normy enables interoperability, safety, and market access; they may be normative (mandatory) or informative (guidance).

In mathematics, norma is a function that assigns a nonnegative length or size to vectors or functions. For a vector x, a norm satisfies non-negativity, definiteness, scalability, and the triangle inequality. Common examples include the Euclidean norm (L2), the Manhattan norm (L1), and the maximum norm (L∞).

In medicine and biology, normy often appear as reference ranges or normal values for laboratory tests, used to interpret results. In linguistics, normative grammars or dictionaries describe standard language forms. Across disciplines, normy convey a sense of standard, benchmark, or acceptable criterion against which other things are compared.
