What is a security door, and why do we require them?
Simply put, and as the name indicates, a security door provides boosted defense and protecting from numerous undesirable circumstances and circumstances; as an effect they are most likely to be sturdy and of very solid (frequently but not always metal) building, and excellent care will have been taken on their style. There are numerous reasons we may need them, chief among which are:
preventing undesirable access (mindful as always of emergency situation evacuations).
preventing or decreasing the passage of fire and/or smoke.
safety-- a design that gets rid of the possibility of fingers getting trapped in the door.
Implications of not setting up security doors ...
Well, there are numerous, and they all hinge (no pun planned) on being not able to avoid the undesirable things happening: if your doors are not protect then it's simpler for people to ΠΟΡΤΑ ΑΣΦΑΛΕΙΑΣ break in and steal or harm your products and residential or commercial property; fire and smoke will spread out far more rapidly; and people's fingers can get caught in closing doors. So we're discussing various points on the scale which vary from real loss of life through breaking the law and contravening policies through significantly harmed hands and fingers through loss/damage of/to important properties to raised insurance premiums ... with all sorts of industrial implications.
Need we state more?
PAS 24.
This is your guarantee that the door is being kept an eye on by a UKAS accredited accreditation body to make sure compliance with PAS 24:201.
Enhanced security performance requirements for doorsets and windows in the UK. External doorsets and windows planned to use a level of security appropriate for houses and other buildings exposed to similar risk and the specific and the appropriate product specific requirement for general performance referenced in BS 6375 Components 1, 2 and 3.
PAS 24, like many British Standards, is a minimum requirement. In other words it doesn't consist of higher or lower grades for security, therefore doors that are tested to the requirements of the basic either pass or stop working. Although a few of the doorsets that pass will be a little stronger than the minimum required, a minimum basic motivates engineers to design the door to pass at the minimum requirements. This makes economic and environmental sense and the effectiveness of doors certificated to this requirement has actually proven that the minimum levels set by the British Standards were just about spot on.
Classes of use.
Since there are all sorts of different environments where security doors are required, many of which are used by the general public, as you may expect there is a British Standard to help assist you through what http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/ΠΟΡΤΕΣ ΑΣΦΑΛΕΙΑΣ kind of door you need: DD171:1987.
The standard sets out 4 levels or classes of use:.
Light task-- radio frequency of use and probably not that severe, such as in a private home.
Medium task-- medium frequency of use, some possibility of a mishap, however the door is not normally used by the public-- for example an internal workplace door.
Heavy duty-- lots of usage, consisting of by the public, and a fairly high possibility of a mishap-- for instance in a retail outlet.
Severe duty-- the only image you require to have in your mind here is a school when the bell opts for playtime and all the children run towards the door. Enough stated!
