ISO 10221:1993 PDF

Scope: This International Standard lays down the material specifications of solid vulcanized rubber sealing rings used in ductile iron pipelines carrying potable water. It also specifies requirements for their effect on the organoleptic properties (colour, taste and odour) and the total organic carbon content of water. In the case of composite seals (which comprise, for example, both rubbers which are rigid and rubbers which are flexible), this International Standard is ap- plicable only to the requirement for their effect on the total organic carbon content of water. Cellular and closed-cell rubber seals are not covered by this International Standard. NOTE 1 This International Standard is applicable only in the absence of more stringent national standards and regu- lations.
