Flexible sheets for waterproofing - Determination of shear resistance of joints - Part 2: Plastic and rubber sheets for roof waterproofing
This European Standard specifies a method for determining the resistance to shearing of joints between two adjacent sheets of the same plastic or rubber sheets for roof waterproofing.
NOTE The shearing characteristics of a joint between two widths of plastic or rubber sheets vary considerably depending on the material, method of jointing, the size of the overlap and the workmanship.

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Scherwiderstands der Fügenähte zwischen zwei benachbarten Dachabdichtungsbahnen fest, die aus dem gleichen Kunststoff oder Elastomer bestehen.
ANMERKUNG Die Scherkennwerte einer Fügenaht zwischen zwei Kunststoff oder Elastomerbahnen unterscheiden sich merklich in Abhängigkeit von Werkstoff, Fügeverfahren, Größe der Überlappung und Art der Arbeitsausführung.

Overview
EN 12317-2:2010 - "Flexible sheets for waterproofing - Determination of shear resistance of joints - Part 2: Plastic and rubber sheets for roof waterproofing" is a CEN European Standard that specifies a laboratory method for measuring the shear resistance (shear strength) of joints between adjacent plastic or rubber roofing membranes. The procedure characterises membranes and joints as supplied (product-level testing), and is intended to support quality control, product development and specification of roof waterproofing membranes.
Key topics and requirements
- Scope: Measurement of resistance to shearing of joints between two widths of the same plastic or rubber roof sheets. Not a system-level test for installed membranes.
- Test principle: Pull a prepared joint specimen in shear at constant speed until rupture; continuously record tensile force and failure mode.
- Specimen preparation & conditioning: Test pieces conditioned ≥20 h at (23 ± 2) °C, 30–70% RH; after jointing, condition ≥2 h at (23 ± 2) °C and (50 ± 5) % RH (unless manufacturer specifies otherwise). Five specimens (50 ± 1 mm wide) taken perpendicular to the joint.
- Apparatus & settings: Tensile testing machine with continuous force/extension recording, capacity > 2000 N, grip width ≥ 50 mm, grip separation speed (100 ± 10) mm/min. Force-measuring system must meet EN ISO 7500‑1 Class 2 (±2%).
- Test geometry & procedure: Initial grip separation so the joint is centred with an initial distance of (200 ± 5) mm; clear grip distance during test = 3–4 × joint width (min 120 mm, max 200 mm). No preload; record maximum force for each specimen.
- Evaluation: Report individual values (N) for five specimens, calculate mean and standard deviation. Record mode of failure (see Annex A). Discard tests with slippage > permitted limit or breaks < 10 mm from grips.
Applications and users
- Practical uses:
- Manufacturer quality control for production batches of plastic and rubber roof membranes.
- Product development and R&D to compare jointing methods, overlaps and materials.
- Third‑party testing laboratories for certification and conformity testing.
- Specifiers and consultants evaluating membrane performance and workmanship sensitivity.
- Contractors / roofers interested in joint performance data to inform installation methods.
- The standard helps assess how material, jointing method, overlap size and workmanship affect joint shear performance.
