Requirements & testing procedures for the LPCB approval & Listing of intruder resistant security glazing unit
Alongside the BS EN356 you have an alternative type of Security Glass, LPS1270. The standard for the glass runs alongside LPS 1175, and is referenced as LPS 1270. This glass has been tested against intruders that are more calculative and use specialised tools to gain entrance.
The tools used are categorised and time limits are given when the test is carried out, indicated by the table below.
To view the products that can incorporate LPS 1270 glazing, see the below links.
Security Counters and Screens - Physical, Ballistic or Blast Resistant Counters for any application to keep staff secure
Attack/Intruder Resistant Windows - EN356 rated attack resistant windows protecting against planned or surprise attacks.
Attack/Intruder Resistant Doors - LPS1175 rated doors for multi-purposes. Manufactured bespoke to customers requirements.
Below is an indication of the types of tools/categories that are covered in the LPS 1270 standard
Tool Category A – The tools of this category are selected in order to simulate an opportunist attack by bodily physical force and by stealth using minimal tools, and includes knives, levers, glass cutters, and punches.
Tool Category B – This tool category provides a more determined opportunist attack by physical force and tools with a higher mechanical advantage, and includes claw hammers, hand drills, and junior hack saws.
Tool Category C – This tool category is for deliberate forced entry of well-protected premises using bodily physical force and a wide selection of attack options, and includes axes, cold chisels, crowbars, cordless electric drills, and wood chisels.
Tool Category D – This tool category is for experienced attempts at forced entry, and includes disc grinders, fire axes, hooligan bars, cordless jig saws, and sledgehammers.
Tool Category D+ – This tool category is for experienced attempts at forced entry, and includes circular saws, reciprocating saws, and 18 volt drills.
The glass is coded with three numbers, when referring to the frame rating e.g. LPS1175 SR3 it usually denotes the last number in the code so a 013 or 123 glass would provide the corresponding security rating.
1st Digit - Local Penetration - 8 mm (-0 mm/+3 mm) by 25 mm (-0 mm/+3 mm) rectangular section.
Note: This is to determine resistance to creation of a hole through which a piece of wire, screwdriver lever, or other such device can be passed.
2nd Digit - Hand Hole - 60 mm (-0 mm/+3 mm) diameter.
Note: This is to determine resistance to creation of a hand hole through which to operate an unprotected thumb turn to release the bolt work.
3rd Digit - Complete Access - Elliptical section of 400 mm (-0 mm/+3 mm) major axis by 225 mm (-0 mm/+3 mm) minor axis.
Note: This directly reflects the size of aperture specified in LPS 1175 and ensures the glazing offers resistance to complete access through the glass
Once again this product can be incorporated into secondary or primary glazing and can be sealed into a double glazed unit to offer insulation and acoustic properties.
