Par ailleurs ce document inclut des dispositions additionnelles pour des robinets déjà commercialisés et installés mais non prévues par la version antérieure 2011 ; une section spécifique sur les aspects dimensionnels, de construction, de fonctionnement, de marquage et de notices d'installation pour les robinets de coupure destinés à être assemblés exclusivement à des appareils à gaz de production de chaud, de froid ou d'électricité est rajoutée.
