SIST EN 1107-1:2000

SIST EN 1107-1:2000 is the Slovenian adoption of EN 1107-1:1999. It specifies a method for determining the dimensional stability of bitumen sheets for roof waterproofing, mainly sheets with flexible plastic-based reinforcement. It is meant for manufacturers, laboratories, and quality control teams that need a repeatable way to check how these sheets change size or shape.

What does SIST EN 1107-1:2000 specify?

SIST EN 1107-1:2000 specifies the determination of dimensional stability for bitumen sheets used in roof waterproofing. In practice, that means it is a test standard for checking whether a sheet keeps its dimensions under the test conditions defined by the standard.

The standard applies primarily to bitumen sheets with flexible plastic-based reinforcement. Sheets with other bases, and sheets without reinforcement, may also be tested using the same method, which makes the document useful beyond one narrow product type.

SIST EN 1107-1:2000 does not apply to bitumen sheets with metal internal foils or with metal facings. For buyers and specifiers, that exclusion matters because it tells you when this test method is not the right one for the product in hand.

What are the key requirements of SIST EN 1107-1:2000?

SIST EN 1107-1:2000 focuses on one main task: determining dimensional stability. The practical point is to verify whether a roofing sheet remains dimensionally sound enough for its intended use, rather than to assess appearance or general durability.

• Check the right product family. The standard is aimed at bitumen sheets for roof waterproofing, especially those with flexible plastic-based reinforcement. This helps a lab or purchaser choose the correct test for the material being evaluated.
• Use the method for compatible variants too. Sheets with different bases, and sheets without reinforcement, may also be tested. In practice, this broadens the method’s usefulness when a supplier offers more than one reinforcement type.
• Exclude metal-faced products from use. Sheets with metal internal foils or metal facings are outside the scope. That matters because using the wrong method can produce results that are not meaningful for acceptance or comparison.
• Work with a dimensional stability test. The standard is about how the sheet behaves dimensionally under test, so the outcome is a measurement or assessment of size change. This is important for roofing because movement in service can affect fit, overlaps, and detailing.
• Use it for comparability. Because the method is standardized, different laboratories can apply the same approach and compare results more reliably. That supports incoming inspection, product development, and supplier qualification.
• Apply it to roof waterproofing materials. The scope is specific to roofing sheets, so it is a material test for roofing applications rather than a general plastics or polymer standard.

What terms does SIST EN 1107-1:2000 define?

Dimensional stability - the ability of a sheet to keep its dimensions when tested, which matters because excessive change can affect installation and long-term performance.

Bitumen sheets - waterproofing sheets made with bitumen as the key waterproofing material, used here for roof applications.

Flexible sheets for waterproofing - sheets designed to stop water ingress while still being flexible enough to handle and install on roofs.

Flexible plastic-based reinforcement - a reinforcement layer based on flexible plastic material that supports the bitumen sheet and helps it perform in use.

Roof waterproofing - the application area covered by the standard, where the sheet is used as part of a roof system to resist water penetration.

Metal internal foils - metal layers inside a sheet that are excluded from the scope of this test method.

Metal facings - metal outer facing layers that also place a product outside the scope of this standard.

Who uses SIST EN 1107-1:2000?

SIST EN 1107-1:2000 is used by manufacturers of bitumen roofing sheets, testing laboratories, quality assurance teams, and technical buyers. It is relevant when a supplier needs to show that a roof waterproofing sheet meets a dimensional stability requirement, or when a buyer wants a consistent test basis for comparing products.

Roofing product developers use it during formulation and reinforcement selection. Inspection and purchasing teams use it when checking technical documentation or acceptance test results for flexible sheets for waterproofing.

What does the SIST EN 1107-1:2000 document contain?

SIST EN 1107-1:2000 contains a focused test method for determining dimensional stability in bitumen sheets for roof waterproofing. The document also sets the scope boundaries by identifying the sheet types included and excluded, which is important for correct application.

As a laboratory or quality document, it is intended for testing and product verification rather than for installation guidance. Its value is in giving a common method so that results from different tests can be compared on the same basis.
