AS 4654 is the primary Australian standard that relates to the physical performance properties of waterproofing membranes specified for use in external, above ground Independent Testing Australia waterproofing systems applied to roofs, decks, balconies and planter boxes in buildings to prevent water ingress and protect structures from moisture damage. It is essential to carefully consider each area of a building’s integral requirements when selecting a high-quality waterproofing membrane to ensure long-lasting protection against water ingress. Waterproofing membranes are crucial elements in construction projects, used to ensure the buildings, roofs, and other structures are protected from water damage whilst preventing dangerous conditions such as mould, mildew, corrosion, or rot. These standard covers test methods for both liquid and sheet waterproofing membranes. Compatibility between waterproofing membranes and substrates, primers, topcoats, sealants, et
Don’t risk your insurance claim, legal case, or property transaction with biased or non-accredited testing. More importantly, you get truly unbiased results — which is priceless when making decisions about your property. NATA accreditation involves ongoing assessment, not just a one-time audit. ISO certification typically covers management systems and processes, while NATA accreditation specifically assesses technical competence in testing and calibration. This eliminates any possibility of bias and ensures our results are truly objective.

It can be equipped with plate sets of different channel heights to optimize flow and pressure, with the M39L plate set designed for low to medium viscosity liquids and the M39H plate set for high viscosity liquids. All components are manufactured in compliance with FDA and EEC regulations, ensuring safe and reliable operation. With adjustable channel heights, it optimizes flow and pressure and supports the simultaneous testing of up to seven different membrane types. Engineered to support demanding research conditions, the Alfa Laval LabStak™ M20 module tolerates high operating temperatures and pressures and is compatible with the full portfolio of Alfa Laval flat sheet membranes. This flexible unit is designed for plate-and-frame operation and allows Independent Testing Australia you to adjust the membrane area quickly and easily using two external stay bolts and a low-end flange with full stroke. The membrane is mechanically supported by rigid hollow plates with numerous slots that allow the permeate to collect and be removed from the module via the permeate collecting tubes.

However, classification alone doesn’t indicate overall quality—a high-performing membrane is one that meets all the relevant testing criteria outlined in the standard. Wow, no wonder there’s so many waterproofing issues and “membrane breakdown” do you know if Aus standards are the same? So when you want to test the longer term performance of something in a really short time, you add heat. Many of these tests are done in less than a week, but as Grayson Wagner (GW)(see report below) comments, Independent Testing Australia it’s the long term absorption that is important and interesting to us. There are reams and reams of standards used to verify the water absorption rates which are acceptable for different membrane
Its extremely important to make sure that when deciding which technologies you are chosing to use on your next project that you are partnering with the right people. Independent Testing Australia (ITA) is equipped with specialised apparatus to test materials and provide data to coating manufacturers, specifiers, builders and waterproofers to determine product suitability for use in the Australian construction industry and satisfy documentation requirements of the Australian Building Code (BCA), the National Construction Code (NCC) and Australian Paint Approval Scheme specifications (APAS
As a result, our Australian and international clients have confidence that they will receive consistently reliable results and service that meet NPAAC, AS ISO and AS ISO/IEC standards. NATA accreditation is important in providing market confidence that our members have adhered to national accreditation standards. This continuous Independent Testing Australia oversight ensures that our partner laboratories maintain their standards over time. NATA accreditation is based on ISO/IEC 17025, which includes all ISO 9001 requirements plus additional technical requirements specific to testing laboratories. Know that your samples are analysed by independently assessed laboratories operating to ISO/IEC international standard
That is a made up link between a test and building code compliance using ‘that’s the way we’ve always done it’ and ‘it’s been working’ as supporting evidence. It’s then entirely unclear to me how this test is being applied and relied on as demonstration of building code compliance. For the correct membrane application, the moisture content of the substrate should be measured prior to any application. The selection of materials and waterproofing systems is critical in preventing differential movement caused by shrinkage and expansion of materials and finishes. This ensures that water splashing from the shower will be contained within the area and not damage the surrounding wall
