Elastomeric Seals - Materials requirements for pipe joint seals used in water and drainage applications - Part 2: Thermoplastic elastomers

This standard specifies requirements for materials used for moulded seals only of thermoplastic elastomers (TPE) used in joints of:
1) thermoplastic piping systems for non pressure waste water discharge (intermittent flow up to 95°C) inside buildings; 2) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow up to 45°C and intermittent flow up to 95°C);
3) thermoplastic rainwater piping systems. General requirements for finished joint seals are also given; any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design.

Elastomer-Dichtungen - Werkstoff-Anforderungen für Rohrleitungs-Dichtungen für Anwendungen in der Wasserversorgung und Entwässerung - Teil 2: Thermoplastische Elastomere

Diese Norm spezifiziert die Anforderungen an die Werkstoffe für Dichtungen aus thermoplastischen Elastomeren (TPE), die für die folgenden Verbindungen verwendet werden: 1) Rohrleitungssysteme aus thermoplastischen Rohren für drucklos betriebene
Abwasserleitungen in Gebäuden (zeitweiliger Durchfluß bis 95°C), 2 ) Rohrleitungssysteme aus thermoplastischen Rohren für drucklos betriebene unterirdische Abflußleitungen und Abwasserkanäle (ununterbrochener Durchfluß bis 45°C und zeitweilig bis 95°C), 3) Rohrleitungssysteme aus thermoplastischen Rohren für die Regenwasser-ableitung. Allgemeine Anforderungen an die fertigen Dichtungen werden ebenfalls angegeben. Alle zusätzlichen Anforderungen, die für die jeweilige Anwendung erforderlich sind, sind in den
einschlägigen Produktnormen spezifiziert; dabei wird berücksichtigt, daß die Leistungs-fähigkeit einer Rohrleitungsdichtung eine Funktion der Werkstoffeigenschaften des Dicht-rings, der geometrischen Form des Dichtrings und der Konstruktion der Rohrverbindung ist.

Garnitures d'étanchéité en caoutchouc - Spécification des matériaux pour garnitures d'étanchéité utilisées dans le domaine de l'eau et du drainage - Partie 2: Elastomeres thermoplastiques

Cette norme détermine les spécifications pour les matériaux utilisés dans les garnitures d'étanchéité uniquement en caoutchouc thermoplastique pour : 1) les réseaux d'évacuation sans pression en thermoplastiques (écoulement intermittent jusqu'à 95°C) à
l'intérieur des bâtiments 2) les réseaux d'évacuation et d'assainissement sans pression, enterrés (écoulement continu jusqu'à 45°C et
intermittent jusqu'à 95°C); 3) les réseaux d'évacuation d'eaux pluviales. Des spécifications générales pour les garnitures d'étanchéité finies sont également données. Des exigences supplémentaires imposées par une application particulière sont spécifiées dans les normes de produit correspondantes, en tenant compte que la performance des joints de canalisations dépend des propriétés du matériau de la garniture d'étanchéité, de la géométrie de cette garniture d'étanchéité et de la conception du joint.

Overview

EN 681-2:2000 - Elastomeric Seals: Materials requirements for pipe joint seals used in water and drainage applications - Part 2: Thermoplastic Elastomers (TPE) - specifies material requirements for moulded TPE seals used in non-pressure thermoplastic piping systems. The standard addresses seals for indoor wastewater (intermittent flow up to 95°C), underground drainage and sewerage (continuous up to 45°C, intermittent up to 95°C), and thermoplastic rainwater piping. It also provides general requirements for finished joint seals while noting that additional, application-specific requirements are set out in relevant product standards.

Key Topics

• Scope & applicability
  • Material requirements limited to moulded TPE seals for non-pressure thermoplastic piping systems.
  • Applications include non-pressure wastewater, underground drainage/sewerage, and rainwater systems.
• Temperature performance limits
  • Intermittent service up to 95°C (indoor wastewater and intermittent flow cases).
  • Continuous underground drainage up to 45°C; intermittent exposure up to 95°C.
• Material characteristics
  • Requirements focus on the suitability of thermoplastic elastomers (TPE) for long-term sealing performance.
  • Emphasis on properties that influence sealing: compound quality, aging resistance, and dimensional stability.
• Design interaction
  • Recognises that joint performance depends on seal material properties, seal geometry, and pipe joint design.
• Finished seal requirements
  • General provisions for finished joint seals are included; product standards provide any additional application-specific criteria.

Applications

• Building services: internal waste and soil stacks, sanitary appliance connections where non-pressure wastewater flows intermittently at elevated temperatures.
• Civil drainage: underground non-pressure drainage and sewer systems where continuous service temperatures are typically lower.
• Rainwater systems: external thermoplastic rainwater piping where TPE seals resist environmental exposure and provide reliable joints.
• Who uses this standard
  • Seal and TPE manufacturers (material selection and compound specification)
  • Pipe and joint system designers (ensuring compatibility of seal material and geometry)
  • Testing laboratories and certification bodies (material compliance checks)
  • Specifiers, installers, and authorities responsible for water and drainage systems

Related Standards

• EN 681 series (other parts cover different elastomer types and requirements)
• Relevant product and piping standards that define joint performance criteria and application-specific tests

EN 681-2:2000 is essential for ensuring that TPE pipe joint seals meet recognized material requirements for reliable performance in water and drainage applications.
