ISO 6804:2016
Rubber and plastics inlet hoses and hose assemblies for washing-machines and dishwashers — Specification
ISO 6804:2016 specifies the requirements for three types of rubber or plastics inlet hoses and hose assemblies for washing-machines and dishwashers connected to the domestic water supply at a pressure not exceeding 1 MPa (10 bar).
It is applicable to the following types of hose:
- type 1: rubber hoses for unheated water supply (maximum temperature 70 °C);
- type 2: rubber hoses for heated water supply (maximum temperature 90 °C);
- type 3: plastics hoses for unheated water supply (maximum temperature 60 °C).
There may be national requirements for hose fittings and hoses conveying drinking water which must be complied with.
