Further to our previous announcement dated the 11th June concerning our FBLS fire block louvre system, we are pleased to advise that following a successful fire test, original assessment C129754 has now been re-issued (as issue 3) by Warringtonfire.
This means that with immediate effect all sizes, including the 4 sizes which were previously totally withdrawn from sale (254x1524mm, 305x1524mm, 457x914mm and 457x1524mm), can again be specified and used in previously tested steel doorsets for a duration of up to 240 minutes to BS 476: Part 22: 1987 (integrity only).
Therefore, our steel door BS476 evidence is now exactly as it was before, main criteria being; up to 240 minute duration, all sizes, and no below 1000mm fitting stipulation.
Furthermore, due to the size we tested, we have widened our scope and can now offer widths up to 813mm wide cut-out. Previously this was 610mm wide.
This is great news as I’m sure you’ll agree and emphasises our commitment to only offer product which you can rely on.
A copy of assessment report C129754 issue 3 is obviously available upon request for a full explanation of criteria.
Sorry for any inconvenience this temporary change in test evidence may have caused, but we hope you understand that it was totally out of our control, and we have addressed it as quickly as possible.
If you require any further clarification, please feel free to contact us.
We write to bring to your attention a very recent development with some of the test evidence relating to our FBLS fire block louvre system, for steel fire door applications.
The main evidence we use for our FBLS in steel fire doors is original assessment report C129754 to BS 476: Part 22: 1987. This report assesses all sizes of the system up to 457x1524mm (width x height) and for a duration of up to 240 minutes (integrity only). This report was up for review recently, and although it has been reviewed & revalidated on several occasions previously, unfortunately we have now been advised by Warringtonfire that they cannot produce a new revalidation and therefore we have to re-test.
We obviously asked for an explanation behind this decision and we were advised that assessments are conducted in line with the PFPF guidelines, this document is currently being updated/amended in light of recent events, with a general tightening up of the requirement when conducting assessments. The PFPF guide states that assessments shall be based on test reports, the assessment in question (C129754) does not actually use any test data, rather it is evaluation on expected performance. Therefore, in the current climate we must have some base test data on the louvre system to be able to assess the range of products currently included within C129754.
Unfortunately, until we re-test we are left in no position but to withdraw from sale with immediate effect any FBLS over a size of 610x610mm (area equivalent) and over a duration of 120 minutes, for steel fire door applications. This actually only withdraws 4 current stock sizes; 254x1524mm, 305x1524mm, 457x914mm and 457x1524mm (all width x height).
You may be wondering why we are not totally withdrawing the product from sale; this is because we do have assessment report number WF170066 to BS EN 1634-1: 2000, which is still validated and covers any size up to 610x610mm, and for a duration up to 120 minutes (integrity only), providing they are mounted below 1 metre from the threshold.
If you have actually carried out your own independent testing of our FBLS louvre system in your door, then this notice does not apply to you.
We are planning to carry out a test during the coming months with Warringtonfire to hopefully allow us to put the larger sizes back on sale. We will obviously keep you fully informed.
This is totally out of our control as we are sure you appreciate, but we are addressing it as our top priority. If you require any further clarification, please feel free to contact us.
Unfortunately, due to a decrease in demand, rising costs and short shelf life we are withdrawing from our range the intumescent sealant cartridges shown on page 72 of our latest no. 21 catalogue.
There is no set date for this as it will be as and when we run out of stock of each one, so please contact us if you have any immediate requirement as we do still have some stock.
We do hope this does not cause any inconvenience, and we haven’t made this decision lightly, but have just found ourselves in a position where this is the only commercially viable option.
Due to the recent increase in demand we have all seen for black architectural ironmongery, we’re excited to announce the launch of two new finishes to our range of Slimport circular vision frames; ZERO black and LITE black.
ZEROblack is a flat, matt style, finish giving a pure stunning black at all angles. LITEblack is a textured finish which enables light to catch the texture giving a multitude of black tones.
Why just have black lever handles when you can now compliment these with a contemporary black vision frame…
After the successful launch of the Anemostat LoPro-STC acoustic vision frame set, we decided to further increase its depth of testing by undertaking some acoustic tests with the bestselling glasses we supply here in the UK.
The LoPro has now been sound tested with our most popular glasses, in both single pane form and incorporated into double glazed units. The range of glasses tested included non-fire rated options such as 6mm toughened and 6.4mm laminated, and also fire rated options such as Pyrocet, Firelite and Pyroshield 2. We even tested 7.5mm thick Anti-Bandit laminated glass.
Now we have a UK tested solution where an acoustic rated vision frame is required, with the glass you use. Full details of the testing carried out can be found here.
We are excited to announce that our Finprotect Plus range of finger protection devices are now tested to the new British Standard BS 8613:2017 “Finger Protection Devices for Pedestrian Doors”.
Furthermore, the range was tested to the more onerous Class 2 of the standard, which tests the ability of the device in preventing fingers entering the gap between the door and frame when force is used. Class 1 devices would not undergo this part of the testing.
BS 8613 was written to provide guidance on the best finger protection devices for doors. With a variety of products already on the market, it was felt that there was no guidance as to what works well, what fails easily, what is durable and what is truly safe in use.
With this new testing you can now specify and use Finprotect Plus with confidence.
Full details of the Finprotect Plus range can be found on our website at www.zeroplus.co.uk/finprotect and a copy of the test report is available upon request.
Following a recent successful fire test, we are pleased to report that the ZEROplus 7200 Series lockcases are now positively assessed for use on 240 minute uninsulated steel fire doors.
The 7200 Series of Euro Profile DIN standard lockcases have been available from Zero for some time, but were previously only covered for 60 minute steel fire doors. Knowing the market calls for more than this, Zero re-tested, and are now excited to bring this development to you.
The 7200 Series is a range of high quality heavy-duty Euro Profile lockcases, with 60mm backset and 72mm centres. Manufactured in accordance with DIN 18251 and CE marked to EN 12209:2003, with a supporting DoP. Modular in design meaning one door prep suits all functions. The range offers a heavy sprung stainless steel clamping follower, solid stainless steel latch and deadbolts, reversible latchbolt and a one piece stainless steel square or radius forend. The latchbolt is light sprung for easy operation and is also guided, while the deadbolt has a 20mm double throw. The existing range offers the four main functions; sashlock, deadlock, latch and nightlatch.
Furthermore, and to complement the 7200 series, we are excited to advise that our ranges of lever handles, escutcheons and euro profile cylinders are now also positively assessed for 240 minute steel fire doors. Therefore, we can offer a complete tested lock set.
ZEROplus has introduced a range of fire and smoke tested self-adhesive silicone fin seals, to complement its popular teardrop seals, 188S, 488S and 388S.
The 1771S (single fin) and 1772S (twin fin) have been developed specifically as meeting stile seals in response to requests from steel door manufacturers to solve the problem of sealing meeting stiles on pairs of fire rated doors. With Tee fins at 90 degrees, both can be fitted to either the astragal or the leading edge on a pair of doors. The 1773S (available soon) and 1777S have Tee fins at 75 degrees and can be used as perimeter seals fitting into the rebate across the head and down both sides of the frame.
All four seals have been positively assessed for use on insulated or uninsulated fire rated steel doors, for a duration up to 240 minutes to BS EN 1634-1. This new range has also recently been included in a series of smoke leakage tests and achieved the requirements of BS EN 1634-3. Copies of all reports are available upon request.
They are all supplied with double sided backed PSA (pressure sensitive adhesive) tape and are suitable for internal and external doors. These products are currently only available in black, although they may be available in dark bronze, white and grey depending on quantity.
Please contact us for more information.
With many of our products being fitted to both the external and internal faces of outward opening doors, we are often asked for information regarding a products resistance to the elements, and in particular, corrosion. Test data relating to corrosion resistance may already be available for some of the specialist door hardware we distribute, especially the CE marked items, but for a lot of products it’s not. Although not an essential characteristic for most items, we at Zero like to have the answer!
Therefore, across a wide range of products, we have carried out some independent Corrosion Resistance testing to BS EN 1670:2007 at a UKAS accredited laboratory. BS EN 1670:2007 specifies the requirements for the corrosion resistance of building hardware for doors, windows, shutters and curtain walling. It provides a method of classification of corrosion resistance of building hardware based on its performance in a neutral salt spray test. BS EN 1670:2007 is the standard used for corrosion resistance testing in many harmonised European door hardware standards such as BS EN 1125 and BS EN 12209 for instance.
Briefly, testing involves placing products in a chamber ready to be sprayed with a salt water solution for a set number of hours. We decided to test for Grade 4 corrosion resistance, which is a 240 hour duration test, and classified as Very High Corrosion Resistance. We opted for Grade 4 as it is rarely tested to for door hardware with Grade 3 (96 hours) seeming to be the norm.
We are pleased to advise that the following products were successfully tested to Grade 4; Outside Access Devices for panic & emergency exit hardware, surface mounted Door Stays, Door Stops, Lever Handles, Escutcheons, Pull Handles, Cylinder Pulls, Door Viewers, Gate Fittings, Vision Frames both square and circular, Door Louvres, Door Loops both surface mounted and concealed, Flush Bolts, Thresholds, Automatic Door Bottoms, Frame Seals, Rain Deflectors, Brush Strips, Door Selectors and Finger Protection.
We believe having such a broad scope of products tested to Grade 4 will enable them to be specified and used with confidence in general external situations. Please contact us for details on exact products tested, and equally a full test report is available on request.
In recently undertaken independent laboratory Anti-Slip testing, our Modular Thresholds, 6.4mm Low Flat Thresholds and Traction Tread™ Thresholds achieved a ‘low risk’ classification to BS 7976-2.
We are pleased to report that every Zero threshold tested received a ‘low risk’ (lowest possible) classification (36+ PTV) in dry conditions, with the majority of those thresholds tested also receiving this classification in wet conditions. Test evidence in regards to the slip rating of thresholds is regularly asked for in public transport applications.
Testing covered Zero’s wide range of Modular Thresholds, 6.4mm Low Flat Thresholds and their Traction Tread™ Thresholds which have various infill’s to aid grip.
A copy of the test report is available upon request.
