Whether you’re validating products, troubleshooting failures, demonstrating compliance or supporting research, we offer equipment and expertise to help you achieve your desired outcomes.

Supporting your goals

Manufacturers and suppliers 
Verify material and product performance, compare options and generate evidence for product information and market acceptance.

Designers and engineers 
Get robust test data to support design decisions, assess fitness for purpose and reduce uncertainty around performance and durability.

Regulators and agencies 
Use independent testing to support compliance decisions, investigate issues and help ensure products meet expected safety and performance requirements.

Researchers 
Extend your own lab capability and collaborate with us to investigate material behaviour, degradation and system performance. 

A smarter materials testing lab

  • Independent testing backed by BRANZ expertise in building science and product performance.
  • Ability to tailor test programmes to your product, use case and applicable standards.
  • Instrumentation and analysis support to help you interpret results and apply them to design, compliance or product development.
  • Option to integrate materials testing with other testing (e.g. structural or fire) when your project spans multiple performance requirements.

Types of materials testing on offer

Mechanical testing 
Mechanical testing examines material strength, stiffness and potential points of failure to ensure products meet performance requirements.

Moisture and water interaction 
Moisture and water interaction testing includes evaluating absorption, permeability and wetting/drying effects, where relevant to your application.

Durability and weathering 
Durability and weathering assessments help you understand how materials perform over time when exposed to environmental conditions.

Comparative testing 
Comparative testing assists in material selection, validating design changes or benchmarking performance against industry standards.

Investigative testing 
Investigative testing is used for root-cause analysis to diagnose and resolve issues occurring during manufacturing or on-site installation.
