Flexible sheets for waterproofing - Bitumen sheets for roof waterproofing - Determination of form stability under cyclical temperature changes

This European Standard describes the test for form stability of metal faced and/or metal cored bitumen sheets fully bonded to a substrate. Other types of bitumen sheets can also be tested in accordance with this standard where appropriate.

Abdichtungsbahnen - Bitumenbahnen für Dachabdichtungen - Bestimmung der Formstabilität bei zyklischer Temperaturänderung

Diese Europäische Norm beschreibt die Bestimmung der Formstabilität bei zyklischer Temperaturänderung. Diese Prüfung ist hauptsächlich anwendbar für Bitumenbahnen mit Kaschierungen und/oder Einlagen aus Metallbändern, die vollflächig mit ihrer Unterlage verklebt werden. Diese Prüfung ist nicht zur Anwendung auf Dampfsperrbahnen bestimmt.

Feuilles souples d'étanchéité - Feuilles d'étanchéité de toiture bitumineuses - Détermination de la stabilité de forme lors d'une variation cyclique de température

La présente norme europénne décrit l'essai permettant de déterminer la stabilité de forme de feuilles d'étanchéité bitumineuses sous l'effet de variation de température cycliques. Elle s'applique principalement aux feuilles protégées ou armées avec des feuilles métalliques en adhérence totale avec leur support. Cet essai n'est pas applicable aux pare-vapeurs.

Overview

EN 1108:1999 is a CEN (European) standard for flexible sheets for waterproofing - specifically bitumen sheets for roof waterproofing - that defines the procedure for the determination of form stability under cyclical temperature changes. The standard is aimed primarily at metal-faced and/or metal-cored bitumen sheets that are fully bonded to a substrate, but it also allows testing of other bitumen sheet types where appropriate. The standard has been adopted nationally (e.g., SIST EN 1108:2000).

Key Topics

• Scope and applicability
  • Defines the sheets and construction types covered (metal-faced / metal-cored, fully bonded).
  • Notes applicability to other bitumen sheets where relevant.
• Test purpose
  • Measures the sheet’s ability to retain shape and adhesion when exposed to repeated temperature cycles (thermal cycling / cyclical temperature changes).
• Specimen preparation
  • Addresses testing of sheets bonded to an appropriate substrate to reproduce in-service assembly.
• Test procedure and equipment
  • Describes the thermal cycling regime, observation points and the method to record form changes (dimensional change, buckling, detachment).
• Assessment and acceptance
  • Provides criteria for assessing form stability and identifying failure modes relevant to roof waterproofing performance.
• Standard identifiers
  • ICS classification: 91.100.50 (Binders, sealing materials), 91.060.20 (Roofs).

(Note: EN 1108:1999 focuses on test method requirements rather than prescriptive product performance values.)

Applications

EN 1108:1999 is used by:

• Manufacturers for product development, quality control, and demonstrating resistance to thermal cycling for metal-faced / metal-cored bitumen roofing sheets.
• Independent testing laboratories to perform standardized form-stability testing used in certification and type approval.
• Specification writers, architects and roofing contractors who require evidence that a membrane will maintain form and adhesion under temperature fluctuations common in roof assemblies.
• Certification bodies and regulatory authorities for compliance assessment and labeling of roof waterproofing materials.

Practical benefits include improved long-term roof performance, reduced risk of thermal-induced deformation or detachment, and clearer evidence for product selection in climates with large diurnal or seasonal temperature swings.

Related standards

• EN 1108:1999 should be used alongside other European standards covering flexible sheets for waterproofing and bituminous roof products. Consult the CEN catalogue or national standards body for the relevant companion standards and national implementations (e.g., SIST EN adoptions).
