Building hardware – Lever handles and knob furniture
What does the term “door furniture” mean?
Door furniture is a term in general use meaning handles that operate the wide variety of locks and latches in today’s market place. The locks could be either mortise (let into leading edge of the door) or rim (surface mounted). The furniture has to suit the type of lock specified. Upright mortise locks usually require lever handles. Knobs might be used on upright locks with deeper backsets, or on horizontal locks, to ensure the user will not ‘rap’ their knuckles against the doorframe whilst operating the knob.
It’s rare to specify knobs on commercial contracts these days, due to the introduction of the Equality Act 2010, as well as BS 8300:2009. Public buildings and workplaces must be accessible to people with disabilities, and knobs can pose problems for many users, because of the need to both grip and twist. A lever can often be operated by a closed fist, or even and elbow, making its operation much easier for many people BS 8300 states “it should be possible to operate all door opening furniture one-handed. Without the need to grasp or twist” It also states “Wherever possible, door opening furniture used in conjunction with locks and latches should have a lever action. Knobs with a spherical, circular or similar design… are difficult to use by people with limited dexterity, arthritis or a weak grip.”
Scope
The European standard specifies the performance requirements and test methods (i.e. durability, static strength, operating torque, corrosion, safety, etc.) for sprung and un-sprung lever handles and knobs for doors on backplates or roses. It applies only to lever handles and knobs that operate a lock or latch. The standard has 4 grades of performance. Compliance with the standard ensures a margin of strength in excess of that needed for normal operation. The standard has additional graded safety requirements where a high risk of failing exists.
Classification
Almost all European architectural hardware standards follow a common format to help ease their understanding by users. Each product is classified under a number of performance headings and, generally, these are the same for all products. All products are “marked” with a size or more digit classification coding which shows, in fine detail, just what levels of product performance are being claimed for the item. The classification system when applied to all items of architectural hardware, will enable complementary items all to be specified to, for instance, a common level of corrosion resistance, category of use, door mass, etc. BS EN 1906 classifies door furniture by using an 8-digit coding system.
