Mortice Locks

Introduction

The EuroArt range of architectural locks is manufactured to the highest engineering standards and designed to offer a high price/performance ratio. They have been successfully type tested to all the requirements of BS EN12209.

Features & Functions

EuroArt DIN architectural range of Locks and latches designed to support the entire EuroArt range of levers, knobs and other unsprung furniture. The range is suitable for general commercial and heavy industrial use.

Offering complementary build quality, design integrity, and choice of external finishes, EuroArt guarantees the perfect match between form and function whenever you specify EuroArt architectural ironmongery. With fire safety and security in mind, EuroArt has design this series. Solid stainless steel latch bolts, deadbolts, followers, forend and strike plates provide enhanced durability and security.

Rebate conversion are available to allow locks to be fitted in most rebated door sections.

  • Stainless steel forend and strike plate.
  • Reversible latch bolt.
  • Solid stainless steel spindle follower.
  • Flush fitting case rivets and screws.
  • Solid stainless steel deadbolt.

BS EN12209 Building Hardware-mechanically operated locks, latches and locking plates.

BS EN 1906 classifies door furniture by using an 8 digit coding system. A similar classification applies to all building hardware product standard so that complementary items of hardware can be specified to, for instance, a common level of corrosion resistance, the category of use, etc. Each digit refers to a particular feature of the product measure against the standard's performance requirements.

1. Category of Use

Four grades are identified:

Grade 1:

Low frequency of use by people with high incentive to exercise care and a small chance of misuse, Eg: Internal residential doors

Grade 2:

Medium frequency of use by people with some incentive to exercise care but where there is some chance of misuse, Eg: Internal office doors

Grade 3:

High frequency of use by public or others with little incentive to exercise care and with a high chance of misuse, Eg: Public doors

2. Durability

Twelve grades are identified with minimum figures for deadbolt and snib operation, and latch bolt operation with and without side load, as shown. The side load is applied to the latch bolt when it is being withdrawn.

3. Door mass

Nine grades are identified with minimum figures for closing force at various door masses as shown. Note: closing force is from a standing start i.e. fully extended latch bolt in contact with the striking plate at the start of test.

4.Fire Resistance

Four grades are identified:

Grade 1:

Not approved for use on fire/smoke door assemblies

Grade 2:

Suitable for use on fire/smoke door assemblies

Note 1:

A grade 1 classification means only that the lock has been designed for use on fire/smoke control doors; the actual fire performance achieved(e.g fire integrity of 30 minutes on a partially glazed timber door etc.) will be contained in a separate fire test report.

Note 2:

Where a product is intended for fire/smoke door use (i.e a "1" in box 4), it must be possible to demonstrate compliance with the Essential Requirements of the Construction Products (Amendments) Regulations. It is recommended that the product should bear the CE mark (see section on CE marking).

5.Safety

No requirement, but note: a lock or latch conforming to this standard can, at the same time, also be part of an exit device conforming to BS EN 179 or BS EN 1125.

6. Corrosion resistance

Nine grades are identified with minimum figures for closing force at various door masses as shown. Note: closing force is from a standing start i.e. fully extended latch bolt in contact with the striking plate at the start of test.

7. Security and drill resistance

Seven grades are identified with minimum figures for requirements relating to physical attack, with or without drilling of the lock case, as shown

8. Field of door application

Fifteen grades are identified for differing applications-hinged or sliding doors with rim or mortice locks with either keyless egress from inside or key locking from both sides. The grading determines which application is appropriate. In addition, there is a requirement that lock/latch should not be removable from outside or, for grades K to R, from inside using "standard" tools. Grades H and P require support for the lock case when installed.

9. Type of Key operation and locking

Nine grades are identified for differing types of key operation. The grading determines how the lock is assessed for deadlocking requirement as shown. In addition, there is a maximum key torque operating requirement of 1.5 Nm and a minimum key strength requirement of 2.5 Nm.

Grade 0:

Not applicable;

Grade A:

Cylinder lock or latch; manually locking;

Grade B:

Cylinder lock or latch; automatically locking;

Grade C:

Cylinder lock or latch; manually locking with intermediate locking;

Grade D:

Lever lock or latch; manually locking;

Grade E:

Lever lock or latch; automatically locking;

Grade F:

Lever lock or latch; manually locking with intermediate locking;

Grade G:

Lock or latch without key operation; manually locking;

Grade H:

Lock without key operation; automatically locking;

10. Type of spindle operation

Five grades are identified

Grade 0:

lock without follower

Grade 1:

Lock with sprung lever or knob

Grade 2:

Lock with light unsprung lever

Grade 3:

Lock with heavy unsprung lever

Grade 4:

Lock with manufacturer's own specification furniture

11. Key identification

Nine grades are identified relating to the number of differs and levers. Grade 0 relates to a latch with no locking action: -

BS EN 1634 Part 1: 2000

Is the European Fire Safety Standard for determining the fire resistance of door and shutter assemblies including hardware designed for installations within openings incorporated in vertical separating elements (doorsets).

Fire Doors-Locks

The UK construction Products Regulations require locks for use on fire doors to be safe and durable. British/European standards BS EN 12209 is the recognized way of demonstrating compliance and requires that an official Notified Body proves both the product and the manufacturer's factory product controls are satisfactory before CE marking can be applied. It is recommended that locks fitted to Fire doors should be CE marked.

CE Marking

CE marking is the easiest and safest route to providing compliance with the latest UK Construction Products Regulations for hardware used on the fire, smoke and escape doors.

BS8300 & Approved Document "M" of the Building Regulations

These documents recommend that locks should have a minimum of a 55mm backset and that the centers should be a minimum of a 72mm. Locks with keyways above the cylinder are also suitable.
