A definição padrão nacional para PN é um número adimensional; o PN, que não possui unidade de medida, é apenas uma combinação de letras e números utilizada como referência, relacionada às propriedades mecânicas e dimensionais dos componentes do sistema de tubulações.

A norma HG/T20592 não especifica unidades, mas a norma nacional sim
