Full title and description
ISO 10221:1993 — Ductile iron pipelines — Rubber sealing rings for pipelines carrying potable water. This International Standard specifies material requirements for solid vulcanized rubber sealing rings used with ductile iron pipe systems transporting drinking water, and addresses their potential effects on water organoleptic properties and total organic carbon content.
Abstract
The standard lays down the material specifications for solid vulcanized rubber sealing rings and specifies requirements for their influence on organoleptic properties (colour, taste and odour) and on total organic carbon (TOC) in potable water. For composite seals, the standard applies to the requirements concerning their effect on TOC. Cellular rubber seals without external communication are excluded.

Scope
Specifies requirements for rubber sealing rings used with ductile iron pipelines that convey potable water. The scope covers material characteristics of solid vulcanized rubber rings and their permissible effects on colour, taste, odour and total organic carbon of water used for drinking. The standard excludes cellular rubber or closed-cell foamed rubbers that have no communication with the outside. It also applies, for certain requirements (notably TOC), to composite seals that combine rigid and flexible rubber components.
Key topics and requirements
- Material specification for solid vulcanized rubber sealing rings for ductile iron pipelines.
- Limits and test requirements for effects on organoleptic properties: colour, taste and odour.
- Requirements and testing regarding total organic carbon (TOC) contribution to potable water.
- Applicability rules for composite seals (requirements focused on TOC effects).
- Exclusion of cellular rubber (closed-cell foam) seals that are not in communication with the exterior.
Test liquids, test procedures and references to related water-quality standards are identified or referenced within the standard text.
Typical use and users
Used by manufacturers of rubber sealing rings and gaskets for ductile iron pipe systems, pipeline designers, water utilities, quality-control laboratories and conformity assessment bodies who need to ensure sealing materials are compatible with potable water and do not adversely affect its taste, odour or organic carbon content. Engineers and procurement specialists in water distribution infrastructure consult the standard when specifying joint components.
Related standards
ISO 10221 references and relates to other standards covering rubber materials and water quality testing, for example ISO 4633 (rubber gasket material specifications), ISO 7887 (water — examination and determination of colour) and ISO 8245 (water — guide for TOC dosing and determination). Users often consider these alongside ISO 10221 when evaluating seals for potable water systems.

FAQ
Q: What is this standard?
A: ISO 10221:1993 is an International Standard that specified material and water-quality-related requirements for solid vulcanized rubber sealing rings used with ductile iron pipelines carrying potable water.
Q: What does it cover?
A: It covers material specifications for solid vulcanized rubber rings, and requirements/tests for their influence on organoleptic properties (colour, taste, odour) and on total organic carbon in drinking water; it also states how composite seals are treated and excludes certain closed-cell rubbers.
Q: Who typically uses it?
A: Manufacturers of pipe seals and gaskets, water utility engineers, pipeline designers, test laboratories and procurement/conformity bodies involved in potable water distribution systems.
Q: Is it current or superseded?
A: The ISO record shows ISO 10221:1993 has been withdrawn. Users should consult their national standards body or the ISO catalogue for information on any replacement or newer related standards.
Q: Is it part of a series?
A: It is a standalone International Standard addressing rubber sealing rings for ductile iron pipelines, but it is related to other ISO standards on rubber materials and water-quality testing (see Related standards above).
