Membran Testleri — EN 13707 / EN 13956 / EN 1928

What Is Membrane?

Waterproofing membrane tests determine the performance of membranes used in roof and foundation waterproofing. Water impermeability (EN 1928), tensile properties (EN 12311), static and dynamic puncture resistance (EN 12730, EN 12691), dimensional stability, low temperature bending and behavior after artificial aging are measured.

Purpose of Membrane

The aim is to demonstrate that the membrane will remain waterproof under application and service conditions. Waterproofing is one of the most expensive building components to repair.

Ek yerleri: Membrane insert performance is evaluated in separate experiments

Equipment for Membrane

Water impermeability test setup
Tensile tester
Dynamic and static puncture devices
UV and thermal aging cabinets
Low temperature bending device

Sample Requirements for Membrane

Samples taken from the roll in accordance with the standard
Membrane type, thickness and carrier structure must be declared
If additional performance is desired, an additional sample must be sent.
Samples should not contain any fold marks or damage.

Duration of Membrane

Basic feature experiments are completed within a few days. Artificial aging experiments span weeks due to exposure time and determine the total timetable.

Membrane Procedure

1Samples are taken from the roll in accordance with the standard and conditioned.
2Thickness and mass are measured.
3Water impermeability test is applied.
4Tensile and puncture resistance are measured.
5Low temperature bending is evaluated.
6After aging, the experiments are repeated.

Membrane Acceptance Criteria

EN 13707, EN 13956 and EN 13967 define the properties and test methods to be declared according to the product type; The required level of performance is determined by the application and project specifications. Within the scope of (EU) 305/2011, the test result is not a pass/fail decision, but the performance value to be announced in the Declaration of Performance (DoP). The national regulations and project specifications of the country where the structure where the product will be used determine which performance level is sufficient.

Evaluation of Results

Results after aging are more informative than initial results: many membranes perform well when new but quickly become brittle under the influence of UV and heat. Moreover, even if the membrane itself is impermeable, water enters through the joints and details; Additional performance should be evaluated separately.

Accreditation

EUROLAB holds internationally recognised accreditation obtained from accreditation bodies party to the IAF and ILAC multilateral recognition arrangements, under ISO/IEC 17025 for laboratory testing, ISO/IEC 17020 for inspection and surveillance, and ISO/IEC 17021-1 and ISO/IEC 17065 for system and product certification. This chain ensures the reports and certificates issued are accepted worldwide.

Whether this test can be offered within accredited scope depends on your product and the standard applied; since accreditation is method-based, the scope is confirmed in writing at the quotation stage.

Construction Materials Testing — What Does This Testing Field Cover?

The section below describes the field that the Membrane test belongs to; the conditions and acceptance criteria of this particular test are given in the sections above. The scope specific to your product is confirmed in writing at the quotation stage.

Construction materials testing shows whether a product performs the function it takes on within the structure. A wide field is gathered in this family, from the compressive strength of concrete to the thermal transmittance of glass, from sieve analysis of aggregate to the watertightness of windows.

What sets this family apart from the others is that the result turns directly into a REGULATORY DECLARATION. For products covered by construction products legislation a declaration of performance (DoP) is mandatory, and every essential characteristic in the declaration rests on a test result. Reaction-to-fire class, thermal conductivity, compressive strength, water permeability and release of dangerous substances are declared in this way. The declaration is a legal text carrying the manufacturer's signature; the test record behind it is the first document requested in an inspection.

The second distinguishing feature is that the product is assessed over its SERVICE LIFE. An electronic device runs for five years; a building component stays in place for fifty and is exposed throughout that time to freeze-thaw cycles, UV, moisture, chemical attack and load. Durability tests (freeze-thaw, carbonation, alkali-silica reaction, ageing) therefore carry as much weight in this field as classical strength tests.

Tests are separated by material type and each group has its own set of standards: cement and concrete, aggregate, masonry units, wood-based panels, thermal insulation, glass and glazing units, ceramic tiles, floor coverings, screeds, joint fillers and coating systems. Where the product will be installed determines which set applies — the same panel is assessed against different standards on a wall and on a floor.

Factory production control (FPC) is a continuous component of the field. CE marking on a construction product is not obtained with a single test and then left; the manufacturer must set up a system showing that it monitors production consistency, takes samples regularly and intervenes when there is a deviation. Depending on the product group, this system may have to be audited by a notified body.

Site testing is a separate body of work. In the laboratory the product is approved; on site it is checked that the product really is of the declared class and that it has been applied correctly. Fresh concrete slump, cylinder sampling, aggregate sieve analysis and in-situ watertightness tests fall within this scope.

Method groups in this field

Concrete and cement
Slump, air content and unit weight in fresh concrete; compressive and flexural strength, water permeability and freeze-thaw resistance in hardened concrete. For cement, compressive strength, setting time and composition analysis.
Aggregate
Sieve analysis, particle shape, Los Angeles abrasion resistance, freeze-thaw, alkali reactivity and density/water absorption.
Thermal and energy performance
Thermal conductivity and thermal resistance, calculation of thermal transmittance (U value) in glazing units, solar energy transmittance.
Facade and joinery
Air permeability, watertightness and wind load resistance in windows and doors; fire performance in facade systems.
Fire performance
Reaction-to-fire classification and fire resistance tests; these are two separate concepts and are addressed by separate standards.
Masonry, tile and flooring
Compressive strength, water absorption, abrasion resistance, slip resistance, stain and chemical resistance.
Emissions and dangerous substances
Formaldehyde release from wood-based panels, VOC emissions from construction products, leaching behaviour of aggregates and waste.

Commonly confused in this field

REACTION to fire and RESISTANCE to fire are different concepts: one describes the material's contribution to a fire, the other how long a component holds the fire back.
A declaration of performance is not a certificate; it is the manufacturer's declaration. Notified body involvement varies with the product group and the assessment system.
A test result is valid for the mounting arrangement in which the product was tested. A different substrate, a different thickness or a different joint detail may require reassessment.
A site sample and a laboratory sample are not the same thing. A concrete cylinder taken on site also reflects application and curing conditions; it does not replace product approval.
ASTM and EN construction standards measure similar quantities with different specimens and scales; the results cannot be converted one-to-one.

Which decisions these results support

Declaration of performance (DoP) and CE marking
Establishing and maintaining the factory production control system
On-site conformity control of concrete, aggregate and workmanship
Meeting fire and energy performance requirements
Verifying the technical items in the project and tender specification

Frequently Asked Questions About Membrane

The membrane passed the test but the roof is getting water, why?

Membrane experiments measure material performance; Most of the leaks are caused by joints, details and application errors. Material suitability does not indicate the accuracy of the application.
