BM TRADA – the new name for Chiltern International Fire Ltd.

From July 1st 2013, Chiltern International Fire Ltd. commenced trading under the name of its parent company BM TRADA and at the same time adopted a brand new visual identity.

Historically, the group has delivered its services through a number of individual companies: BM TRADA Certification Ltd, TRADA Technology Ltd, Chiltern International Fire Ltd. (including Chiltern Dynamics) and a network of international offices. Both BM TRADA Group and these individual companies will now trade under the same name - BM TRADA - and adopt the new visual identity.

To coincide with this change, our Technical Reports, Test Reports, Products Assessments, company stationery and marketing collateral have been re-designed to carry the new branding and visual identity.

The validity of all documents previously issued by the individual companies including certificates, test reports and product assessments is unaffected by this change and a letter to this effect will be available to download from our website www.bmtradagroup.com.

About BM TRADA

With origins dating back to 1934, we have a deep history and services which are highly valued by our customers. We offer independent certification, testing, inspection, training and technical services around the world. In all these areas we continue to use industry-leading experts in their chosen fields to develop and deliver services – an ethos that has been at the heart of our approach since we began.

A recent review of our businesses and customers revealed that the individual identities sometimes make communications confusing, and that in an already complex business area, clarity and simplicity in communications is rare, but valued. It also revealed that a single identity and combined offer would help us strengthen our appeal.

With this in mind, we brought the companies together under the name BM TRADA and took the opportunity to create a fresh new visual identity.

We have modernised our image and combined our strengths. However, our values, our people and the integrity of our services remain the same. I hope you will welcome these changes and the improvements they will bring.

1 Introduction

This document constitutes a global assessment relating to Eurospan FD60 fire resisting doorsets, for Egger (UK) Ltd. The assessment uses established extrapolation and interpretation techniques in order to extend the scope of application by determining the limits for the design based on the tested constructions and performances obtained. The assessment is an evaluation of the potential fire resistance performance, if the elements were to be tested in accordance with BS 476: Part 22: 1987.

2 General Description of Construction

The construction for door leaves covered by this assessment comprises the following:

Element Species/type Dimensions (mm) Density (kg/m³)

Stiles & rails None fitted - -

FD60 particleboard 38 thick 576

Facings Egger Eurospan

FD60 particleboard 8 thick 666

Adhesive Lipping

Polyurethane - - Core

Lippings Sapele 8 thick 640

3 Leaf Sizes

Assessment for increased leaf dimensions is based on the design’s performance and the characteristics exhibited during test. Data sheets specifying the maximum assessed leaf sizes and graphs showing the permitted gradient between maximum height and width are contained in appendix D.

Unequal leaf double doorsets are covered by this assessment with no restriction on the smaller leaf dimensions. Doorsets containing leaves with smaller dimensions than those stated are deemed to be less onerous and are therefore automatically covered.

4 Configurations

Based on the test evidence listed in appendix A, this assessment covers the following doorset configurations:

Abbreviation Description

LSASD & ULSASD Latched & unlatched, single acting, single doorset

DASD Double acting, single doorset

5 Leaf Size Adjustment

Eurospan FD60 door leaves of this design may be altered as follows:

Element Reduction

Leaf The manufactured size of the leaf may be reduced in height or width without restriction

Timber lippings The dimensions stated in section 10 may be reduced by 20% for fitting purposes

6 Overpanels

6.1 Solid

Overpanels of the same construction as the door leaves may be used only when separated by a transom. The overpanel must be fully contained within the door frame (see following diagram).

The transom must be to the same specification as the door frame.

Door frame joints must utilise one of the following four methods: mortise and tenon joints, half lapped joints, mitre joints or butt joints (see section 8.2).

All methods require joints to be tight, with no gaps, and require mechanical fixing with the appropriate size ring shank nails or screws. Butt joints must be additionally bonded with urea formaldehyde or equivalent.

Overpanels must be fixed by screwing through the rear of the frame with steel screws passing at least 30mm into the centre line of the overpanel. Fixings must be no more than 100mm from each corner and a maximum of 250mm centres in between.

The intumescent seals specified for the jambs in appendix D may be fitted in the overpanel edges or frame reveal; in either case the frame to overpanel junction is permitted to have a maximum 2mm gap tolerance.

Maximum overpanel heights are as follows:

13.3.12 Letter Boxes/Plates

Letter boxes/plates may be fitted providing the product has demonstrated contribution to the required integrity performance of this type of doorset design, when tested to BS 476: Part 22: 1987 or BS EN 1634-1, when installed in a timber based doorset of comparable thickness. Products may be fitted up to 1200mm from floor level and no closer than 100mm to any leaf edge.

13.3.13 Air Transfer Grilles

Air transfer grilles may be fitted providing the product has suitable test evidence to BS 476: Part 22: 1987 or BS EN 1634-1, demonstrating a minimum 60 minutes integrity performance when installed within a timber based doorset of comparable thickness. Margins to leaf edges are as detailed for glazing and the position of the unit will be dictated by the pressure regime tested for the grille (normally below mid-height). The area occupied by the grille must not exceed 0.2m2 and must be deducted from the assessed glazing area, if both elements are fitted.

If it is required to fit air transfer grilles outside of the aforementioned scope, guidance and appropriate test evidence must be sought from the manufacturer of the grille, including permitted numbers of grilles, spacing within the door leaf, additional intumescents, aperture liners and location within the doorset (with respect to pressure regime).

Lorient Polyproducts Ltd. manufacture a range of intumescent air transfer grilles with an integral smoke control shutter tested to BS 476: Part 31: Section 31.1.



of 38

13.3.14 Cable-Way

Based on the integrity performance of the doorset construction, with no burn-through of the core material, we consider it acceptable to allow the provision for a concealed cable-way to facilitate electro-magnetic closing/latching mechanisms. The cable-way must be concealed in the following way:

1. A hole drilled centrally though the leaf of maximum 10mm diameter.

2. The cable for the electronic closing/latching mechanism must be no more than 2mm smaller in diameter than the hole through the leaf.

3. The cable for the electronic closing/latching mechanism must be PVC encased.

4. Cable-ways are only permitted for use with latched, single leaf, single acting doorsets with maximum leaf dimensions of 2100mm (h) x 900mm (w).

5. The hole must be located below 1500mm from the threshold and must be spaced a minimum of 90mm from any apertures within the leaf, e.g. glazing, air transfer grilles or letter plates, etc.

This approval is subject to the hardware manufacturer having the appropriate test evidence for the product for use with this type of 60 minute construction. Test evidence generated in steel doorsets is not acceptable. Any tested intumescent gaskets for the lockset, closing mechanism, receiver plate, cable loops, etc. must be replicated.

14 Door Gaps

For fire resisting applications, door edge gaps and alignment tolerances must be set within the range defined in the following table:

Location Dimensions

Door edge gaps A minimum of 2mm and a maximum of 4mm

Alignment tolerances Leaves must not be proud of each other or from the door frame by more than 1mm

Threshold 10mm between bottom of leaf and top of floor covering

15 Supporting Construction

The supporting construction must provide the required level of fire resistance designated for the doorset design and be a suitable medium to permit adequate fixity.

16 Fixings

The frame jambs are to be fixed to the supporting construction using steel fixings at 500mm maximum centres. The fixings must be of the appropriate type for the supporting construction and must penetrate to a minimum depth of 50mm. It is not necessary to fix the frame head, although packers must be inserted.

17 Sealing to Structural Opening

The door frame to structural opening gap must be protected using one of the following methods:

1. Gaps up to 10mm must be sealed on both sides with a 10mm depth of acrylic intumescent mastic, fire tested for this application to BS 476: Part 22: 1987 or BS EN 1634-1. Joint must be fitted with 15mm thick architraves overlapping at least 15mm each side.

2. Gaps between 10mm and 20mm must be tightly packed with mineral fibre capped on both sides with a 10mm depth of acrylic intumescent mastic, fire tested for this application to BS 476: Part 22: 1987 or BS EN 1634-1. Architraves are optional.

3. Gaps up to 20mm filled with proprietary fire stopping product (e.g. expanding PU foam or preformed compressible intumescent foam). Products must be tested for this application to BS 476: Part 22: 1987 or BS EN 1634-1. Joint must be fitted with 15mm thick architraves overlapping at least 15mm each side.

4. Timber based or non-combustible subframe up to 50mm thick, with no gaps between the components. Joint must be fitted with 15mm thick architraves overlapping at least 15mm each side.

5. Timber based or non-combustible subframe up to 50mm thick, with gaps up to 10mm between the components filled on both sides with 10mm depth of acrylic intumescent mastic or full depth expanding PU foam, fire tested for this application to BS 476: Part 22: 1987 or BS EN 1634-1. Joint must be fitted with 15mm thick architraves overlapping at least 15mm each side.

Guidance for various methods of sealing the frame to structural opening gap is also given in BS 8214: 2008, Code of practice for timber fire doors, which may be referred to where appropriate.

Note: Drawings are representative of doorset installation only; actual installations must be as the text within this document specifies.

19 Smoke Control

19.1 General

If the doorset design is required to provide a smoke control function to comply with Building Regulations, the doorset must meet one of the following criteria (unless pressurization techniques complying with BS EN 1201-6 are used):

(a) have a leakage rate not exceeding 3m3/m/hour (head and jambs only) when tested at 25Pa under BS 476 Fire tests on building materials and structures, Section 31.1 - Methods for measuring smoke penetration through doorsets and shutter assemblies, Method of measurement under ambient temperature conditions; or

(b) meet the additional classification requirement of Sa when tested to BS EN 1634-3: 2004 - Fire resistance tests for door and shutter assemblies, Part 3 – Smoke control doors.

Smoke seals or combined intumescent/smoke seals that are fitted to the door to achieve the performance requirements specified above must have been tested in accordance with the associated test method. Providing the smoke seals, any interruptions, door gaps, and the type/configuration of the doorset are consistent with the detail tested, the doorset will comply with current smoke control legislation under Approved Document B, and a suffix ‘S’ or ‘Sa’, as appropriate, may be added to the designation. Any other components installed where smoke leakage may occur must also be taken into account.

Note: The incorrect specification and fitting of smoke seals may impair the operation of a doorset and therefore compromise the fire resistance performance. Advice should be sought from the seal manufacturers regarding the correct specification and installation of smoke seals or combined smoke and intumescent seals.

19.2 Further Considerations

Other guidance is available, including BS EN 9999-2008 - Code of practice for fire safety in the design, management and use of buildings, which may impose different or additional requirements. It is the responsibility of the relevant parties to stipulate the precise smoke control specification, prior to commencing manufacture and/or installation.

20 Conclusion

If the Egger Eurospan FD60 doorsets, constructed in accordance with the specification documented in this global assessment, were to be tested in accordance with BS 476: Part 22: 1987, it is our opinion that they would provide a minimum of 60 minutes integrity and insulation (subject to section 18).

Notes:

1. The premature failure at the top hanging corner of the doorset was due to inadequate sealing between the door frame and structural opening during installation. If the sealing had been to the required specification, the doorset would have achieved 61 minutes integrity.

2. Failure on doorset B occurred at the latch position – the latch keep fitted measured 235 x 50mm and fully interrupted both intumescent seals in the frame reveal; although it was bedded onto 1mm thick Interdens. The size of latch keep assessed in section 14.2 is limited to 235 x 25mm; a minimum of 5mm of each seal in the leaf edge must be intact, running past the keep. If a keep of these dimensions had been fitted it is our assessment the doorset would have achieved a minimum of 60 minutes integrity.



of 38

3. The premature failures witnessed at the meeting edges, above the latch position and from

the top hanging corners were not attributable to the glass or glazing system. The other tests conducted on this door core have proven that the door core is capable of performing for 60 minutes under fire test conditions. As no failures were attributable to the glass or glazing system, it is reasonable to assume that including the tested glass and glazing system with this door core will not adversely affect its performance.
