Roughness measurements reveal surface topography variations that influence fouling development and solute interactions. Zeta potential measurement quantifies surface charge magnitude and sign, with highly charged surfaces showing enhanced resistance to colloidal fouling but potentially increased organic macromolecule attraction. Narrow PSD distributions support high selectivity for separation applications, while broader distributions accommodate feeds with variable particle sizes. Pore size distribution (PSD) characterization identifies the distribution of pore diameters throughout the membrane, typically ranging from 0.001 to 10 micrometers depending on membrane type. This guide outlines essential characterization parameters, required instrumentation, standardized testing protocols, and proper interpretation of result
Our slip ratings that we apply to flooring surfaces are endorsed by the National Association of Testing Authorities (NATA) ensuring quality and consistency by qualified scientists that you can rely on. Get in touch using the form below and our experts will get in contact soon! Interested in slip resistance testing or consulting for your organisation? Tests and reports are conducted using Australian and International Standards as well as The National Construction Code. Working with QED, the only NATA accredited laboratory in WA to perform and report on slip tests means our reporting is assured by an independent third party. Ongoing monitoring of in-situ flooring is conducted according to AS 4663 Slip resistance measurement of existing pedestrian surface
By definition, waterproofing is the formation of an impervious barrier which is designed to prevent water entering or escaping from various sections of building structures. They have high adhesion to concrete, and excellent crack bridging capability at 3mm. Remedial waterproofing product solutions used Tensile Strength Testing on existing structures to prevent water ingres
AS/NZS 4858:2004 (R – Internal Wet Area Membranes
Equally important is the prevention of water damage to the internal components of the building, which can result in costly repairs and disruptions. Ensuring that the membrane that you are using complies with the regulatory requirements as outlined within the NCC (National Construction Code) is critically important. Adhesion testing is a destructive test method conducted using aluminium dollies connected to a hydraulic pump to discern the bond strength that a membrane has to the substrate. Adhesion testing is a destructive test most commonly applied on exposed areas such as rooftops and podiums. Australian Standards, the National Construction Code and Housing Provisions outline minimum requirements to be adhered to waterproofing system installations. Holiday Testing is most commonly used on Waterproofing Integrity projects as an efficient testing on exposed membrane.

The samples used in this case are flat bars cut out of larger material using a water jet saw. The load is converted to a stress value and the displacement is converted to a strain value. If one pulls on a material until it breaks, one can find out lots of information about the various strengths and mechanical behaviors of a material. Other information about the mechanical response of a material can also be gathered from a fracture test. Therefore, the atoms elastically stretched will return to their non-loaded position

Scope of Accreditati
Alfa Laval offers a versatile range of small-scale LabStak™ plate-and-frame modules for on-site membrane testing. Advanced capabilities including AFM, zeta potential analysis, and specialized microscopy reveal fundamental mechanisms governing membrane behavior. Contact angle measurement and SEM analysis form the basic toolkit, enabling rapid morphological assessment. Chemical compatibility testing exposes membranes to cleaning chemicals and operational solutions, assessing durability and dimensional stability. Mechanical stability assessment cycles membranes between operational and rest conditions, identifying potential failure modes. This fundamental parameter enables meaningful comparison between membranes of different materials and structures.
