NF ISO 6953-1, E49-330-1 (01/2024)

This document specifies which characteristics of compressed air pressure regulators are to be included in supplier documentation. It also applies to filter-regulators. This document applies to: — manual direct operated types (with exhaust device such as a pressure regulator, or without exhaust device), — manually operated internally piloted types (e.g. nozzle-paddle mechanism), and — pressure-controlled types. Additionally, it specifies product marking requirements for pressure regulators and filter-regulators. This document is applicable to pressure regulators for compressed air for an operating pressure (supply pressure) up to 2500 kPa (25 bar) and for an adjustable regulated outlet pressure up to 1600 kPa (16 bar ) and filter regulators for regulated operating pressure (supply pressure) and outlet pressure of up to 1,600 kPa (16 bar), in which larger impurities are mechanically removed. NOTE The main characteristics to be included in supplier documentation for electro-pneumatic distribution devices with continuous pressure control are specified in ISO 10094-1.
