New Electrical & Plumbing Results and Composite Floor Assessment

We have recently published the most considerable update to our passive fire testing literature to date. This update includes the expansion of our scope in fire testing into electrical penetrations as well as a comprehensive assessment of composite flooring. This advancement in Allproof’s tested installations increases the capability of its industry leading NZ made passive fire protection products.

The most noticeable evolution from the latest PFP literature update is the creation of an electrical testing document. This document solely focuses on a range of electrical and A/C mixed service penetrations. Tested solutions include paircoil, data cable bundles, optic fibre, TPS cables along with other common electrical services that require fire rating. The Allproof flush box intumescent pad (FBINT) has also been included within this document giving a clear overview of all fire rated electrical services. This development means that installers and engineers can now use the same supplier and product across a wider range of services while benefiting from Allproofs New Zealand made advanced intumescent technology. This refines the selection of passive fire products and aids the ordering and installation process whilst supporting local business.


Since its arrival in the market, composite floor systems had proven challenging to fire rate. Allproof lead the market and developed the Drop-In Fire Collar (DIFC) that overcomes installation challenges associated with the undulating profile on the underside of the floor slab and varying depths of concrete cover. This 100% New Zealand made product changed the industry, however as these flooring systems have advanced new profiles and depths have been released. There is a broad range of composite tray profiles that use different topping thickness depending on the span and structural engineering. Along with the different types of plumbing services, pipe material and dimensions it has been a challenge to achieve testing in each possible scenario. Allproof has now added an assessment to their literature allowing the application of DIFC’s on composite floor profile changes of 60, 80 and 210mm, the DIFC’s FRL is equal to that of the composite floor tray up to 120 minutes.

Allproof’s passive fire range is also BRANZ appraised. This provides confidence that the range has been rigorously examined by BRANZ, a trusted independent organisation. As part of this process, Branz methodically reviews Allproof’s test reports verifying the results and audits the technical manual to ensure compliance and technical accuracy. To provide additional assurance, Allproof’s quality system and manufacturing process are also evaluated to ensure ongoing product quality. The resulting BRANZ appraisal [No.1088] provides assurance to the passive fire industry that Allproof’s products provide outstanding performance and compliance.

Allproof manufactures and tests products with a clear objective in mind; to create systems that streamline specification and installation while achieving the highest result possible. This ultimately improves the cost by removing additional components or products and saving time. Allproof’s intumescent is known for its excellent performance, this means that Allproof don’t need to over-engineer their systems. Often a simple collar and a little sealant will provide ample protection. Allproof also publishes all their spec sheets, install information and test results on their website with no access restrictions. Allproof believes in removing barriers and making it as easy as possible for customers to research, select and install their products. There is a passive fire newsletter database that is optional; this provides notifications on new developments across this fast moving product range. Click here to sign up.
