Limited Flame Spread
This European Norm is often used for lower level Flame Resistant protective garments such
as Socks, Rainwear and Hi-Visibility Waistcoats. It is divided into 3 classes, where Index 3 is the
highest.
1. The flame does not spread, there are no flaming debris, no afterglow, a hole may be formed.
2. The flame does not spread, there are no flaming debris, no afterglow, no hole formation.
3. The flame does not spread, there are no flaming debris, no afterglow, no hole formation, the after-flame times
of each individual specimen is less than 2 seconds.
It is important to note that Index 3 garments should be worn in conjunction with EN ISO 11612 garments, and Index 1
garments should not be worn next to the skin.
EN 388
Protective Gloves against Mechanical Risks
EN 388 is the European standard used to evaluate mechanical risks for hand protection, and to
be legally sold in Europe, a glove has to be certified to this standard. Gloves with an EN 388 rating
must be third-party tested and are rated on a score of 1-4 for abrasion, cut, tear and puncture
resistance and on a scale of 1-5 for cut resistance.
It is well accepted that the majority of hand injuries are caused by cuts and abrasions, with the most serious being
cuts. As a result, the latest editon of this standard incorporates the Coup Test and the ISO 13997 standard which uses
a TDM-100 machine for a more accurate measure of cut resistance.
Gloves certified to the new standards will display 2 extra components to the markings as shown in the diagram.

LOI – LIMITED OXYGEN INDEX
LOI is the amount of oxygen you need in an atmosphere for a material to ignite. The LOI value is
one way to give an indication of the level of FR protection that a garment provides and makes it
easier for users to compare and choose the correct level of protection.
In our atmosphere there is 21% oxygen, so anything which has an LOI of less than 21 will burn
readily, such as cotton which has an LOI of 17. Protex Q is a popular modacrylic FR fibre and has an LOI of 34 and
aramid fibres often have an LOI of around 28-29.
