Flexible sheets for waterproofing - Part 1: Bitumen sheets for roof waterproofing - Determination of dimensional stability

This European Standard specifies the determination of the dimensional stability of bitumen sheets with flexible plastic-based reinforcement. Sheets reinforced with different bases or those without reinforcement may also be tested using the standard. It is not applicable to bitumen sheets with metal internal foils or those with metal facings.

Overview

EN 1107-1:1999 is a CEN European Standard that defines how to determine the dimensional stability of bitumen sheets used for roof waterproofing. The standard focuses on bitumen sheets that are reinforced with a flexible plastic-based reinforcement, but it also permits testing of sheets reinforced with different bases or unreinforced sheets. It explicitly excludes bitumen sheets that incorporate metal internal foils or metal facings.

This standard is relevant to manufacturers, testing laboratories, specifiers and roofing contractors who require consistent, comparable data on how roofing membranes behave dimensionally under specified conditions.

Key Topics

• Scope and applicability: Dimensional stability testing for bitumen roof waterproofing sheets with plastic-based reinforcement; other base types and unreinforced sheets may be tested under the same standard where appropriate.
• Exclusions: Not applicable to bitumen sheets with metal internal foils or metal facings.
• Purpose: Provide reproducible measures of dimensional change to support product specification, quality control and conformity assessment.
• Stakeholders: Manufacturers, conformity assessment bodies, architects and roofing system designers.

Keywords: dimensional stability, bitumen sheets, roof waterproofing, plastic-based reinforcement, CEN, test methods, quality control.

Applications

This standard delivers practical value across the lifecycle of roofing materials and projects:

• Quality control: Manufacturers can use the standard to verify that production batches meet dimensional stability expectations and reduce product variability.
• Product specification: Architects and specifiers can reference EN 1107-1:1999 when selecting membranes for projects where dimensional behavior affects installation or performance.
• Performance assessment: Test laboratories and independent assessors can produce comparable results for durability evaluations and technical data sheets.
• Procurement and compliance: Contractors and owners can use the standard as part of acceptance criteria for supplied roofing membranes.

Related Standards

EN 1107-1:1999 sits within the family of European standards addressing flexible sheets for waterproofing and roofing materials. Users should consult CEN publications and national adoptions for complementary standards covering:

• Other test methods for mechanical, thermal and endurance properties of bitumen waterproofing sheets.
• Product specifications and nomenclature for roofing membranes and sealing materials.

Note: National adoption records (for example, SIST EN 1107-1:2000 in Slovenia) may exist; check the relevant national standards body for the officially endorsed text and any national annexes.

For implementation, refer to the official EN 1107-1:1999 document from CEN or your national standards body to ensure correct test procedures and interpretation.
