NATA Accreditation — Independent Testing Australia
Independent Testing Australia (ITA) is an AS/ISO 17025 and NATA-accredited precision material testing laboratory, specialising in the analysis of membranes and coatings used in the Australian construction industry.
ITA's newly awarded NATA accreditation for AS 4654.1 strengthens our capability in waterproofing membrane testing and confirms that all AS 4654.1 testing we perform is now fully NATA-endorsed. This milestone reinforces our commitment to delivering reliable, independently verified results and gives our clients greater confidence in the quality, credibility, and compliance of their products.
Under the Building Code of Australia (BCA), external above-ground waterproofing systems must comply with AS 4654.1 and AS 4654.2 to meet nationally recognised performance requirements for durability, weatherproofing, and long-term protection of building elements. Fully NATA-endorsed AS 4654.1 testing provides the independent verification needed to demonstrate compliance with these requirements, reducing regulatory risk and ensuring that waterproofing systems meet the expected standards for performance and reliability.
What This Accreditation Means For You
For Manufacturers
Fully NATA-endorsed AS 4654.1 testing provides a powerful validation of product performance and a clear competitive advantage in the market. It demonstrates that a membrane has met the rigorous requirements of the Australian Standard, supporting stronger product claims, smoother market acceptance, and increased confidence from specifiers, builders, and regulatory bodies. It enables manufacturers to present independently verified evidence of quality and durability, strengthening their position in both domestic and international markets.
For Building Specifiers & Architects
Fully NATA-endorsed AS 4654.1 testing ensures that membrane performance claims are independently validated, reducing risk and supporting more robust specification decisions. It strengthens the chain of assurance from product selection through to on-site performance, helping design professionals meet compliance requirements with confidence.
For Builders
Using products that have been tested and fully endorsed under AS 4654.1 means greater confidence that the membranes installed meet the performance requirements expected on Australian job sites. Accredited testing helps reduce the risk of product failure, rework, and costly defects by ensuring the materials used have been independently verified for durability, adhesion, and long-term waterproofing performance — supporting builders in delivering compliant, reliable outcomes.
For Waterproofing Installers
AS 4654.1-tested and NATA-endorsed membranes provide assurance that the products applied have been independently validated for performance and durability before reaching the job site. This reduces uncertainty around product suitability, supports correct system selection, and helps installers deliver work that aligns with both manufacturer requirements and BCA expectations. Using membranes backed by accredited testing also strengthens installers' documentation and quality assurance processes, helping protect against disputes, callbacks, and warranty issues.
CodeMark Certification Support
AS 4654.1 testing plays an important supporting role for manufacturers pursuing CodeMark certification. CodeMark assessors rely on robust, independently verified evidence of compliance with the relevant Australian Standards. While CodeMark is a broader conformity scheme, AS 4654.1 testing provides the critical technical foundation that underpins the product's performance claims and strengthens the credibility of the certification process.
