Synergy are Setting the Standards

Product Standards

Offering solutions to suit all projects, applications and budgets our comprehensive range is designed and tested to perform to stringent international standards, providing customers with confidence when specifying the Synergy brand.  Here are details of some of the standards relevant to our products;

CE Marking

CE marking is mandatory to those products where the BS EN standard has been harmonised under the Construction Products Regulation (CPR). As of July 2013 it became compulsory for manufacturers to apply CE marking to any of their products if they fall within the scope of a harmonised EN standard before it can be made available on the market.

CE marking is the best way of demonstrating compliance with the latest legislation for hardware used on fire, smoke and escape doors. CE marking indicates that the product is fit for purpose and has been third party performance tested.

To adhere to the Construction Products Regulation, we have Declaration of Performance (DOP) documents for all of our CE marked products listed here.

BS EN1154:1997

The European standard for the performance of controlled door closing devices. It stipulates the minimum performance levels in relation to door width and mass as indicated in the table below. It also classifies products for general suitability for use on fire doors and corrosion resistance. Door Closers must complete 500,000 test cycles without loss of performance.

BS EN 1154:1997 stipulates that closers fitted to fire doors be no less than size EN3. Adjustable closers must be able to achieve this as a minimum.

Power Size Max Door Width Max Door Weight
2 850mm 40kg
3 950mm 60kg
4 1100mm 80kg
5 1250mm 100kg
6 1400mm 120kg

BS EN1155:1997

The standard covering Electronically Powered Hold Open Devices for Swing Doors. This European standard specifies requirements for both electro-magnetic devices incorporated into door closers and hold open magnets. To comply, closers manufactured according to this standard can hold a door at a fixed position or can allow the door to swing freely. In each case interruption to the electrical power supply will cause the door to close positively. Closers must also comply with BS EN 1154.

BS8300 and Approved Document M

The Equality Act provides legislation to remove physical barriers that may prevent people with disabilities from accessing a service and therefore requires service providers to make “reasonable adjustments to the physical features of their premises to overcome any barriers to access “

BS8300-2:2018 and Approved Document M (ADM) of the Building Regulations in England and Wales; specifies the recommended opening forces of door controls to assist less able users like the elderly, young children and the disabled i.e. a door closer must produce an opening force of below 30N between 0 and 30° and below 22.5N between 30° and 60°.

Synergy can provide a specific number of Door Closers to help meet the recommendations of BS8300/ADM. These products perform very efficiently and will ensure the required ease of opening and reliable closing forces are achieved to fulfil these requirements.

Our products have been third party tested and conform to BS EN1154 and BS EN1155 and are CE marked. This ensures you are using products that are fit for purpose and meet the legal requirements, particularly for fire doors.

It should be noted that it is necessary to ensure that the accompanying ironmongery such as hinges, locks, latches and intumescent seals are of high quality and have been installed accurately, therefore assisting the performance of the doorset in regard to achieving the required opening forces. It is recommended to contact the manufacturers directly for information regarding their product specification. Site conditions such as air pressure differentials should also be taken into consideration.

Opening and closing the door with optimum efficiency

Our product range consists of both rack and pinion and cam action type door closers. We are able to provide highly efficient products in both versions and importantly our torque curve graphs demonstrate a rapid decreasing force that is required during the opening cycle. The measurements are taken at a power setting EN3; the minimum requirement for fire doors as detailed in BS EN 1154.

BS EN12209

The European standard for mechanically operated locks, latches and locking plates. It specifies requirements and test methods for durability, strength, security, and function of mechanically operated locks and latches.

BS EN179 Emergency exit Devices

This standard covers devices to be used in emergency situations where the door is in a low occupancy environment where people are familiar with the emergency exit and its hardware and therefore a panic situation is unlikely to develop.

BS EN 179 classifies emergency exit devices by using a 10 digit grading system, each digit referring to a particular feature of the product measured against the standards performance requirement. The particular features in BS EN 179 are identical to BS EN 1125, with three differences affecting Security, Type of Operation and Field of Door Application.

BS EN1634 Part 1  Fire Safety

The European fire safety standard for determining the fire resistance of door and shutter assemblies including hardware designed for doorsets. This standard specifies the methods of tests for Fire Doors. The furnace performance and pressures are defined. Door Controls and Locks can be assessed to be suitable for use on fire doors and its performance is indicated by digit 4 of the classification coding.


Certifire is an independent third party certification scheme that assures performance, quality, reliability and traceability of fire protection products. Recognised by regulatory authorities worldwide, it is an internationally respected mark of fire safety and one of the most authoritative in the industry.

To gain Certifire approval the product must have been independently tested against the relevant BS EN standard to confirm their durability and safety as well as being included in successful fire door tests. They will have been manufactured in a facility that has a recognised Quality Management System in place and audited annually.
