ČSN EN ISO 23553-1   (075870) Bezpečnostní a řídicí přístroje pro hořáky a spotřebiče na kapalná paliva - Zvláštní požadavky - Část 1: Automatické a poloautomatické uzavírací armatury

Anotace textu normy ČSN EN ISO 23553-1   (075870)

This document specifies safety, constructional and performance requirements and testing of automatic and semi-automatic valves for oil.

It applies to automatic and semi-automatic valves which are:

- normally closed,

- used in combustion plants to interrupt the oil flow with or without delay on closing,

- for use with oil types (e.g. middle distillate fuel oil, crude oil, heavy fuel oil or kerosene) without gasoline,

NOTE 1 - For other oil types (e.g. oil emulsions), additional test methods can be agreed between the manufacturer and the test authority.

NOTE 2 - Oil types from petroleum refining processes are classified ISO-F-D in ISO 8216-99 and form part of a device having other function(s), such as oil pumps. In this case, the test methods apply to those parts or components of the device forming the automatic and semi-automatic valves, i.e. those parts which are necessary for the closing function.

- for use on burners or in appliances using oil,

- directly or indirectly operated, electrically or by mechanical or hydraulic means,

- fitted with or without closed-position indicator switches.

This document covers type testing only.
