Stafford Bridge is the leading manufacturer of high security doorsets, bullet resistant doorsets and blast resistant doorsets. Forming part of the Surelock McGill Group, Stafford Bridge naturally adopted the group culture and belief in that products which are ‘fit for purpose’ should be tested and certified to the appropriate standards.

This process is a continuous cycle to ensure that we meet the latest standards providing protection against the latest attack tools and scenario’s.
The company attitude doesn’t change even in relation to new products such as high security windows, ballistic resistant windows and blast resistant windows which have or are currently being tested to meet the required performance standards.

Below, is information relating to some of the significant test standards we have tested against.
Should you require any further information in relation to the products or indeed the test standards please do not hesitate to contact our sales or technical departments.

LPCB LPS 1175 Physical Security Standards for Testing Doorsets

Standard	Title	Scope
LPS 1175	Requirements and testing procedures for the LPCB approval and listing of intruder resistant building components, strongpoints, security enclosures and free-standing barriers	This standard describes tests for classifying the intruder resistance of building components, strongpoints, security enclosures and free-standing barriers. The scope includes the following types of product and system: Access covers and hatches Secondary glazing systems Cladding systems Security grilles Conservatories Security screens Containers Sheds and tool stores Curtain walling systems Shutters Display cases and cabinets Sliding doorsets Hinged and pivot doorsets Strongpoints Fences and gates Temporary buildings Folding doorsets Tool containers Garage doorsets Turnstiles Partitioning systems Void protection screens Roofing systems Windows Roof lights and skylights Walls The intruder resistance of the product itself plus any in-situ hardware, such as locks and hinges, and any associated form of locking, such as padlocks, are tested. The intruder resistance of the complete building component, strongpoint, security enclosure or free-standing barriers, and any associated hardware is classified regardless of design or materials used in their construction. Where the product comprises an opening element and a frame or retaining guides, the element and its frame or guides are tested as a combination, locked accordingly. Each opening configuration is subject to a separate evaluation. The adequacy of the installation/fixing method defined by the manufacturer is assessed. However, it is assumed that the substrate onto which the product is fitted provides a resistance to attack at least equivalent to that afforded by the product itself. The standard does not cover the classification of individual components such as glass, infill materials or locks in their own right, other than as part of the products tested. Classification of the intruder resistance afforded by such components is covered by other Loss Prevention Standards, including: • LPS 1242 - Requirements and testing procedures for the LPCB approval and listing of cylinders for locks • LPS 1270 - Requirements and testing procedures for the LPCB approval and listing of intruder resistant security glazing Resistance to electrical manipulation is not tested other than by attack methods possible using the tools defined within this standard. It is therefore recommended that electronic components used to operate the product are also tested and approved to relevant operational and safety standards. Resistance to thermal shock attack, chemical attack, vehicle impact, explosion and ballistics are outside the scope of this standard, as is durability and other general performance. The resistances to scaling over and tunnelling under free-standing barriers are also outside the scope of this standard. Notes: i) For guidance, the security rating system is loosely based upon domestic risks (1 and 2), commercial risks (2, 3 and 4), high security risks (5 and 6) and extremely high security facilities (7 and 8). ii) The security rating applies to the prime barrier. No provision is made for enhancement of a product by means of a secondary barrier and it is not the intention of this standard to prohibit such an arrangement. iii) Other LPS and EN standards exist for classification of security products not covered by LPS 1175, e.g. safe storage units, strongrooms, protection devices for personal computers, office furniture, high security locks, thief resistant locks etc. iv) The performance of building components, strongpoints, security enclosures and free-standing barriers to other characteristics such as fire resistance, acoustics, durability and weathertightness, may be covered by other LPS, BS, EN and ISO standards. Contact LPCB for further information.

LPCB LPS 1673 Physical Security Standards for High-Risk Individuals

What is LPS 1673?

Developed by LPCB, the standard draws on extensive research conducted by the National Protective Security Authority (NPSA), the UK government’s national technical authority for physical and personnel protective security. The standard’s development was also supported by National Counter Terrorism Security Office and the US Bureau of Diplomatic Security.

Products tested and certified to LPS 1673 carry third-party approval for the effective levels of protection against these fast-moving, violent forced entry attempts. This covers targeted attacks on high profile individuals in their homes or places of work, as well as marauding terrorist attacks.

European Standard for Fire Resistance of Doorsets

Standard	Title	Scope
EN 1634-1	Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware Part 1: Fire resistance test for door and shutter assemblies and openable windows	This European Standard specifies a method for determining the fire resistance of door and shutter assemblies and openable windows designed for installation within openings incorporated in vertical separating elements, such as: a) hinged and pivoted doors; b) horizontally sliding and vertically sliding doors including articulated sliding doors and sectional doors; c) folding doors, sliding folding doors /shutters; d) tilting doors; e) rolling shutter doors; f) openable windows; g) operable fabric curtains. This European Standard is used in conjunction with EN 1363-1. The testing of fire dampers is covered by EN 1366-2. The testing of closures for conveyor systems is covered by EN 1366-7. By prior agreement with the test sponsor, additional information may be gained for individual elements of building hardware in order to fulfil the performance criteria identified in EN 1634-2. Based on the observations recorded during the test, the results may be presented in a separate report which should be in accordance with the requirements of EN 1634-2.

European Standards for Bullet Resistance

Standard	Title	Scope
EN 1522	Windows, doors, shutters and blinds - bullet resistance - Requirements and classification	This standard defines the requirements and classification that windows, doors, shutters and blinds must satisfy when tested in accordance with EN 1523. This standard is applicable to attacks by hand guns, rifles and shotguns on windows, doors, shutters and blinds complete with their frames and infills, for use in both internal and external locations in buildings. Shutters and blinds must be tested separately and not in conjunction with a window or door, in order to achieve classification in terms of bullet resistance. This standard gives no information on the behaviour of the test item when subjected to other types of stresses. It gives no information on the bullet resistance of the junction between the frame and the wall or other surrounding structure.

Standard	Title	Scope
EN 1523	Windows, doors, shutters and blinds – Bullet resistance - Test method	This European Standard defines a test procedure to permit classification of the bullet resistance of windows, doors, shutters and blinds (complete with their infills). This European Standard concerns only behaviour in respect of the frame of the windows, doors, shutters or blinds, their infills and the junctions between the infills and frames. If the windows and doors are subjected to specific conditions of climate, specific conditions of test may be required. It does not apply to the testing of glass infills. For the testing of glass infills refer to prEN 1063. This European Standard gives no information on the behaviour of the frame subjected to other types of stresses. It gives no information on the bullet resistance of the junction between the frame and the wall or other surrounding structure. Shutters and blinds must be tested separately and not in conjunction with a window or door, in order to achieve classification in terms of bullet resistance. NOTE Care should be taken to ensure that all joints between the surrounding wall and the window, door, shutter or blind will have bullet resistance at least equal to that of the window, door, shutter or blind.

European Standards for Blast Resistance

Standard	Title	Scope
EN 13123-2	Windows, doors, and shutters — Explosion resistance — Requirements and classification — Part 2: Range test	This European Standard specifies the criteria which windows, doors and shutters shall satisfy to achieve a classification when submitted to the test method described in EN 13124-2. This European Standard concerns a test method against blast waves in open air resulting from high explosives that can be carried by hand and placed a few metres from a target. At such close distances blast values vary across an attack face. Controlled measurement of the actual blast on the face of the test specimen being difficult, costly and subject to inaccuracy, consistency of the blast forces is therefore controlled in this European Standard by the characteristics of the explosive charge and its location. This European Standard covers only the behaviour of the complete unit including infill, frame and fixings as tested. It gives no information on the ability of the surrounding wall or building structure to resist the direct or transmitted forces. If the windows, doors and shutters are intended for specific conditions of climate, specific test conditions can be required (see clause 4). This European Standard gives no information on the explosion resistance capacity of the wall or other surrounding structure.

European Standards for Acoustics

Standard	Title	Scope
EN ISO 717-1	Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation	This part of ISO 717: a) defines single-number quantities for airborne sound insulation in buildings and of building elements such as walls, floors, doors, and windows; b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building and traffic outside a building; c) gives rules for determining these quantities from the results of measurements carried out in one-third-octave or octave bands in accordance with ISO 10140-2, ISO 140-4, and ISO 140-5. The single-number quantities in accordance with this part of ISO 717 are intended for rating airborne sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty (except for spectrum adaptation terms). The required numerical values of the single-number quantities are specified according to varying needs. The single-number quantities are based on results of measurements in one-third-octave bands or octave bands. For laboratory measurements made in accordance with ISO 10140, single-number quantities should be calculated using one-third-octave bands only. The rating of results of measurements carried out over an enlarged frequency range is dealt with in Annex B.

CE MARKING OF DOOR HARDWARE

Standard	Title	Scope
EN 1125	Building hardware — Panic exit devices operated by a horizontal bar, for use on escape routes — Requirements and test methods	This European Standard specifies requirements for the manufacture, performance and testing of panic exit devices mechanically operated by either a horizontal push-bar or a horizontal touch-bar, specifically designed for use in a panic situation on escape routes. The suitability of a panic exit device for use on fire/smoke resisting door assemblies is determined by fire performance tests conducted in addition to the performance tests required by this European Standard. Annex B indicates additional requirements for these products. This European Standard covers panic exit devices which are either manufactured and placed on the market in their entirety by one producer or produced by more than one producer and subsequently placed on the market as a kit in a single transaction.

Standard	Title	Scope
EN 179	Building hardware — Emergency exit devices operated by a lever handle or push pad, for use on escape routes — Requirements and test methods	This European Standard specifies requirements for the manufacture, performance and testing of emergency exit devices mechanically operated by either a lever handle or a push pad for the purpose of achieving a safe exit under an emergency situation on escape routes. The suitability of an emergency exit device for use on smoke/fire-resisting door assemblies is determined by fire performance tests conducted in addition to the performance tests required by this European Standard. Annex B indicates additional requirements for these products. This European Standard covers emergency exit devices, which are either manufactured and placed on the market in their entirety by one producer, or produced by more than one producer and subsequently placed on the market as a kit in a single transaction.

Standard	Title	Scope
EN 1935	Building hardware — Single-axis hinges — Requirements and test methods	This European Standard specifies requirements for single-axis hinges, of lift-off or fixed pin type, for use on access windows and doors. Such windows and doors may or may not be fitted also with door closing devices. It includes tests for static loads, shear strength and allowable wear during durability cycling for the following hinges: a) mounted on the edge of the door leaf or window sash and opening in one direction only; b) whose axis of rotation is within 30 mm of an edge of the movable element for a door leaf mass of up to 160 kg; c) whose axis of rotation is within 30 mm of the edge for a window sash with a mass up to 60 kg. This European Standard classifies hinges for four categories of use (see annex A) and also specifies the maximum permissible torque arising from frictional resistance generated within the hinge during endurance testing. Corrosion protection requirements are specified for those hinges which are not intended to be protected after fitting. There are no restrictions on the materials or the methods of fabrication used providing the hinge conforms to the requirements relevant to its application. The suitability of single axis hinges for use on fire/smoke compartmentation door assemblies is determined by performance tests conducted in addition to the performance tests required by this European Standard. Annex B indicates additional requirements for these products. This European Standard does not apply to hinges incorporating spring-assisted door-closing mechanisms. Door closers incorporating door co-ordinator devices (with or without electrically powered hold-open devices) are covered by EN 1158. Although the fastenings used to fix hinges to window assemblies and door assemblies are not covered by this European Standard, if the type of fastening to be used is supplied or specified by the manufacturer, such fastenings are used for the tests. NOTE Performance standards for complete windows and door assemblies (in the course of preparation by CEN/TC 33/WG 1 and TC 33/WG 2) will ensure that the fastenings used to fix the hinge are adequate for their intended duty.
