Overview
EN 1848-1:2025 is a European standard developed by CEN that specifies the method for the determination of length, width, and straightness of bitumen sheets for roof waterproofing. This standard replaces the earlier EN 1848-1:1999 version and provides updated guidelines to ensure precise and consistent measurement practices for flexible waterproofing sheets used primarily on roofs. It supports quality control during manufacturing and installation by defining how dimensions and straightness should be accurately measured.
Key Topics
- Scope and Application: Applies to bitumen sheets used in roof waterproofing, focusing on dimensional accuracy (length, width) and physical straightness.
- Measurement Methods:
- Length: measured in the manufacturing direction using a metal tape or laser tool.
- Width: measured at right angles to manufacturing direction with a tape, ruler, or laser tool.
- Straightness: checked against a straight reference line to detect deviations using chalk or laser lines.
- Sampling and Preparation:
- Testing uses a complete undamaged roll, selected per EN 13416 sampling rules.
- Measurements are taken after the sheet has been unrolled on a flat surface and given time to rest.
- Apparatus:
- Metal measuring tapes, rulers, and optional laser measurement devices.
- Chalked or laser-marked reference lines for straightness assessment.
- Procedure:
- Length and width are measured at defined positions on the roll to obtain representative values.
- Straightness determination involves marking points along edges and measuring maximum deviation from a straight line.
- Expression of Results:
- Length and width results are averages of multiple measurements.
- Straightness results are reported as the maximum deviation found.
- Test Reporting:
- Reports must identify the product, reference the standard, detail sampling and test conditions, and provide measurement results.
Applications
EN 1848-1:2025 is essential for:
- Manufacturers of bitumen roof waterproofing sheets to verify dimensional compliance.
- Quality control laboratories performing standard testing and inspection of waterproofing materials.
- Roofing contractors and specifiers requiring assurance of material conformity before and during installation.
- Regulatory bodies and certification entities involved in construction material standards.
Ensuring accurate dimensions and straightness contributes to improved installation efficiency, waterproofing performance, and reduced material waste.
