Various documents, including BS 8214, stress the importance of specifying the appropriate classification of doors to ensure long-term performance under anticipated uses. At the time of publication of this document these classifications are best derived from tests described in BS DD 171 : 1987, ‘Guide to specifying performance requirements for hinged or pivoted doors (including test methods)’, although equivalent European standards are now available.
The following classifications apply:
LD light duty
Low frequency of use by those with a high incentive to exercise care, e.g. private house owners.
MD medium duty
Medium frequency of use primarily by those with some incentive to exercise care, although with some chance of accidents or misuse.
HD heavy duty
High frequency of use by the public and others with little incentive to exercise care where accidents or misuse could occur.
SD severe duty
Subject to frequent violent usage.
All Leaderflush Shapland doors and doosrets are either HD or SD rated.
