Dahlsens understands the important role product quality plays in building both your business’ success and reputation. That’s why you can count on us to source and supply the safest, and highest quality products on the market.
Building Standards in Australia
Australian building product standards and specifications are in place to ensure the quality and safety of residential and commercial construction. Developed by a committee of representatives including members from industry, manufacturers, government and consumers, Australian standards act as a benchmark for national product quality and performance.
While Australian building standards remain high, Dahslens is vigilant in monitoring the production standards of our suppliers, only offering product ranges that conform to the strictest standards.
How are Standards determined?
Acceptance tests
Acceptance tests are required to demonstrate compliance with standards on a routine basis. Products are classified into Types. “Type A” external use products and “Type B” internal use products. These are then further categorised according to minimum flexural strength.
Type characteristics tests
Type characteristics tests are designed to test the product properties. These relate to the performance of products when in service. All individual characteristic tests follow detailed procedures, and a minimum product performance level must be achieved before approval.
What is the difference between product conformance and compliance?
Non-conforming building products (NCBPs)
According to the Australian Building Codes Board(ABCB), NCBPs include:
- Products that claim to be something that they are not
- Products that don’t meet the required standards for their intended use
- Products marketed or supplied with the intent to deceive those who use them.
Example of a NCBP
A building product that is falsely labelled non-combustible when it is a combustible product.
Non-compliant products (NCPs)
A non-compliant product occurs when a product is used under circumstances that are not in accordance with the requirements outlined in the National Construction Code(NCC).
Example of a NCP
A product marked combustible that is used in circumstances that require a non-combustible product.
How do Dahlsens’ suppliers rate?
Dahlsens only deals with reputable suppliers. Each of our suppliers must produce superior products that meet or exceed relevant Australian standards and compliance measures.
Our experienced team vet each of our suppliers to determine their manufacturing processes and commitment to product safety.
Bradnams: leading the way in bushfire safety
In a dry and bushfire prone country like Australia, fire safety standards are particularly important to home owners. Dahlsens’ supplier, Bradnmans are leaders in the manufacture of widows and doors that conform to strict standards for construction and retrofitting on buildings in a bushfire-prone area.
Building products utilised in areas with a bushfire risk of BAL-12.5 or above, must comply with AS3959: 2009. These protective measures play a vital role in improving the ability of a structure to withstand fire and provide owner or occupant protection.
Bradmans’ exclusive FlameShield Range has received a safety rating that meets BAL-12.5, BAL-19, BAL-29 and BAL-40 standards. Their FlameShield range of bushfire doors and windows include louvre, sliding, awning, casement, double hung and bi-fold windows and sliding, hinged and bi-fold doors.
Technika gas cooktops: cutting-edge safety
Gas can be a silent killer, and this fact has driven recent changes to Australian and New Zealand safety standards. From 1 July 2017, all cooktops are required to include a flame failure device. This means cooktops should automatically cut out or re-ignite when a flame goes out to avoid any unnoticed gas release.
Technika are at the forefront of this technology and were early adopters of flame failure devices.
