Security buyers search by standard and rating, not by brand. This hub explains the standards ArxBridge works to, how their ratings map to products, and where to find the full reference guide for each one.

How the ratings map to products
Each standard answers a different threat. Forced entry standards rate how long a doorset, window or shutter resists attack. Ballistic standards rate which weapons the product stops. Blast standards rate the charge and the distance it was tested at. Fire standards rate how long the product holds back flame, heat and smoke. Vehicle impact standards rate what a barrier stops and how far the vehicle gets.
The table below links to the full guide for each standard. Each guide gives the rating tables, explains how the test works, shows how to read a rating on test evidence, and lists the ArxBridge products rated to it.
| Standard | What it rates | Typical products | Guide |
|---|---|---|---|
| LPS 1175 | Forced entry, tool attack | Security doors, windows, shutters, grilles | LPS 1175 security ratings |
| LPS 2081 | Stealth attack, quiet tools | Doorsets near sleeping or working people | LPS 2081 stealth attack |
| LPS 1270 | Security glazing, attack resistance | Display glazing, secure windows | LPS 1270 security glazing |
| EN 1522 and EN 1063 | Ballistic resistance | Bullet resistant doors, windows, glass | Ballistic ratings: EN 1522 and EN 1063 |
| ISO 16933 | Blast resistance of glazing | Blast resistant windows, curtain walling | Blast ratings: ISO 16933 |
| E and EI | Fire integrity and insulation | Fire rated steel doors, louvre doors | Fire ratings: E and EI |
| PAS 68 and IWA 14-1 | Vehicle impact | Bollards, gates, street furniture | Vehicle impact: PAS 68 and IWA 14-1 |
| Terrorism (Protection of Premises) Act 2025 | Duty to consider protective security | Entrances, barriers, controlled access | Martyn’s Law |
Start from the threat, not the product. Name the attack you need to resist, find the standard that rates against it, then choose the product. A rating is only useful when it answers your threat.
Who specifies these standards
Architects name ratings in the specification so every bidder prices the same performance. Security consultants map the threat assessment to the right standards. Main contractors check that what is delivered matches the test evidence. Facilities and procurement teams use ratings to compare like with like when they replace or upgrade.
For most UK projects the shortlist is small: LPS 1175 for forced entry, EN 1522 where firearms are a risk, ISO 16933 where blast is a risk, fire classifications for compartmentation, and PAS 68 or IWA 14-1 for vehicle mitigation. The products hub shows which product group each threat belongs to.
Frequently asked questions
Which standard do I need for a security door?
For forced entry, LPS 1175, usually SR2 to SR4 depending on the threat. For stealth attack near sleeping people, LPS 2081. Where fire compartmentation applies as well, a fire classification such as EI 60 alongside the security rating. Name the threat first and the standard follows.
What is the difference between a rating and a certificate?
The rating, such as C5 or FB6, is the performance level the product achieved. The test evidence, issued by an independent body such as LPCB, proves which product achieved it. Always ask for evidence naming the exact product, not just the rating in isolation.
Do ratings expire?
Ratings belong to the tested product design. If the design changes, the rating may no longer apply, which is why the evidence must name the exact product as supplied. Standards themselves are revised over time, so name the current issue, such as LPS 1175 Issue 8, in the specification.
