EN 1848-1 Flexible Sheets for Waterproofing - Test for Determination of Width and Flatness

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1848-1 testing. This European standard specifies a method for determining the length, width and flatness of bituminous sheets for roofing.

EN 1848-1 is a European standard that specifies the test method for determining the length, width and flatness of bituminous sheets used for roof waterproofing. The standard is part of the EN 1848 series covering flexible sheets for waterproofing. The test method described in EN 1848-1 involves measuring the dimensions of bituminous sheets and evaluating their flatness.

Below is a summary of the test method:

• Sample preparation: A representative sample of the bitumen sheets is taken and stored in a horizontal position for at least 24 hours prior to testing.
• Length and Width Measurement: The length and width of each sheet are measured with an accuracy of 1 mm using a tape measure or other suitable equipment. Measurements are taken at three different points along the width and length of the plate and the average value is calculated.
• Measuring Accuracy: The flatness of each plate is assessed by placing a ruler across the length and width of the plate and measuring the maximum distance between the ruler and the plate surface. Measurements are taken from three different points along the width and length of the plate and the maximum value is recorded.
• Length, Width and Flatness Evaluation: Measured values ​​for length, width and flatness are compared with the requirements specified in the relevant product standard or technical specification. If the measured values ​​are within the stated requirements, the plate passes the test.

It is important to note that the EN 1848-1 standard also specifies other test methods for sampling, conditioning and packaging of bituminous sheets, as well as evaluating the physical and mechanical properties of the sheets.
