Flexible sheets for waterproofing - Determination of peel resistance of joints - Part 2: Plastic and rubber sheets for roof waterproofing

This European Standard specifies a method for determining the resistance to peeling of joints between two adjacent sheets of the same plastic or rubber sheets for waterproofing.
This test method will be used mainly for testing the joints in mechanically fastened plastic or rubber sheets for waterproofing.
The peel strength characterises the optimum joint strength which can be reached for a membrane and a joint technique under laboratory conditions. On roofs the joint strength could be clearly reduced due to the non-optimal conditions (e.g. pressure, temperature, humidity, pollution, workmanship). The requirement for the joint technique at the site is to ensure a permanently tight joint.

Abdichtungsbahnen - Bestimmung des Schälwiderstandes der Fügenähte - Teil 2: Kunststoff- und Elastomerbahnen für Dachabdichtungen

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Schälwiderstandes der Fügenähte zwischen zwei benachbarten Dachabdichtungsbahnen fest, die aus dem gleichen Kunststoff oder Elastomer bestehen.
Dieses Prüfverfahren wird im Wesentlichen zur Prüfung der Fügenähte von Dachabdichtungsbahnen aus Kunststoff oder Elastomer angewendet.
Der Schälwiderstand kennzeichnet die optimale Festigkeit der Fügenaht, die für eine Abdichtungsbahn unter Laborbedingungen mit einem Fügeverfahren erreicht werden kann. Auf Dächern könnte die Festigkeit der Fügenaht aufgrund suboptimaler Bedingungen (z. B. Druck, Temperatur, Feuchtigkeit, Verschmutzung, Ausführung der Arbeit) deutlich verringert sein. Das auf der Baustelle angewendete Fügeverfahren muss sicherstellen, dass die Fügenaht dicht ist.

Feuilles souples d'étanchéité - Détermination de la résistance au pelage des joints - Partie 2 : Feuilles d'étanchéité de toiture plastiques et élastomères

La présente Norme européenne spécifie une méthode de détermination de la résistance au pelage des joints formés entre deux feuilles d'étanchéité plastiques ou élastomères, attenantes et du même type.
Cette méthode d’essai est principalement utilisée pour soumettre à l'essai les joints des feuilles d’étanchéité plastiques et élastomères fixées mécaniquement.
La résistance au pelage caractérise la résistance optimale du joint, pour une membrane ou une technique de jonction donnée, qui peut être atteinte dans des conditions de laboratoire. Sur les toitures, des conditions non optimales (qui peuvent être liées par exemple à la pression, à la température, à l'humidité, à la pollution, à la main d'oeuvre) peuvent provoquer une nette réduction de la résistance des joints. L'exigence applicable à la technique de jonction sur site a pour but de s'assurer que les joints sont étanches de manière permanente.

Hidroizolacijski trakovi - Ugotavljanje odpornosti proti razslojevanju spojev - 2. del: Polimerni in elastomerni trakovi za tesnjenje streh

Ta evropski standard določa metodo za ugotavljanje odpornosti proti razslojevanju spojev med po dvema enakima polimernima oziroma elastomernima trakovoma za tesnjenje. Ta preskusna metoda se uporablja predvsem za preskušanje spojev v mehansko pritrjenih polimernih oziroma elastomernih trakovih za tesnjenje. Odpornost proti razslojevanju označuje optimalno trdnost spoja, ki jo je mogoče doseči za membrano in tehnologijo izdelave spoja pod laboratorijskimi pogoji. Na strehah bi se lahko trdnost spoja občutno zmanjšala zaradi neoptimalnih pogojev (npr. tlak, temperatura, vlaga, onesnaženost, izvedba). Tehnologija izdelave spoja na mestu samem mora zagotavljati trajno tesnjenje spoja.

Overview

EN 12316-2:2013 is a European Standard developed by CEN that specifies a precise test method for determining the peel resistance of joints between adjacent plastic or rubber sheets used in roof waterproofing. This standard primarily focuses on mechanically fastened sheets and evaluates the optimum joint strength achievable under controlled laboratory conditions. It highlights the importance of assessing peel resistance to ensure that waterproofing membranes maintain a permanently tight joint during their service life, despite varying environmental and workmanship conditions on site.

Understanding joint peel resistance is crucial for manufacturers, installers, and quality controllers involved in roof waterproofing projects. EN 12316-2:2013 provides a reproducible and reliable testing procedure for plastic and rubber sheets that supports high-quality roofing installations.

Key Topics

• Scope:
  The standard applies to plastic and rubber waterproofing sheets for roofs, focusing on the peel resistance of their joints. It evaluates joints formed by the intended installation methods, mainly for mechanically fastened membranes.

• Test Principle:
  A tensile testing machine peels the joint at a constant speed, measuring the tensile force needed to separate the sheets. This force, recorded continuously, characterizes the joint's peel resistance.

• Test Specimen Preparation:
  Test joints are created by manufacturer-recommended methods and conditioned at 23 ± 2 °C for at least 16 hours. Five specimens (50 mm wide) are cut per joint, perpendicular to the overlap.

• Failure Modes:

  • A: Peel of the joint
  • B: Break outside the joint
  • C: Delamination of the sheet (>5% joint area)
    These modes help interpret test results and inform joint durability.

• Results Evaluation:
  The standard defines how to calculate average peel resistance or classify “no failure of the joint” when specimens fail outside the joint area. An average peel resistance is calculated using ten equidistant force values, excluding the first and last quarters of the force-extension graph to ensure accuracy.

• Precision:
  Estimated test variability is about ±10%, making this a reliable method for quality assurance.

• Testing Conditions:
  The test is conducted at standard laboratory conditions (23 ± 2 °C), with a grip separation speed of 100 ± 10 mm/min and specific requirements for gripping and load measurement precision.

Applications

• Roofing Material Quality Control:
  Manufacturers use this standard to verify the joint strength of plastic and rubber waterproofing membranes before release to market, ensuring product compliance and performance.

• Installation Validation:
  Roofing contractors and specifiers assess jointing techniques under controlled conditions to select appropriate methods that guarantee long-term watertightness.

• Research and Development:
  Material developers employ EN 12316-2:2013 to compare adhesive or mechanical joint methods and optimize membrane formulations to improve peel resistance.

• Compliance and Certification:
  Meets European regulatory and industry demands for consistent waterproofing membrane joint testing, supporting CE marking and quality declarations.

Related Standards

• EN 13416 – Sampling for Flexible Sheets:
  Establishes procedures for random and representative sampling of roofing membranes, ensuring test specimens comply with statistical accuracy requirements.

• EN ISO 7500-1 – Force-Measurement Verification:
  Defines calibration and verification processes for tensile testing machines, which are critical for the accuracy of peel resistance tests.

• EN 12316-1 – Bitumen Sheets Peel Resistance:
  A complementary standard for testing peel resistance of bitumen-based waterproofing membranes, useful where multi-material roofing systems are employed.

• Other CEN Standards for Waterproofing:
  EN 13707 (Reinforced Bitumen Sheets) and EN 13956 (Plastic Sheets) provide additional guidance on performance and testing related to flexible waterproofing sheets.
