GCR 105.5
105.5. The use of a back & chest protectors is compulsory at all Tarmac events.
105.5.1 Minimum Requirements
Use of a chest and back protector is compulsory and must be clearly marked with the following norms:
a) The back protector must comply with EN1621-2, CB (“central back”) or FB (“full back”) Level 1 or 2.
b) The chest protector must be:
a) “Full chest protectors” (protector designed as a single piece) and “Divided chest protectors” (protector designed in two separate halves) are permitted. All types of chest protectors (full or divided) must have a minimum protection (total) area of no less than 230cm²
b) Only protectors and in conformity with prEN 1621-3 (level 1 or 2) are admitted.
The “EN” stands for “European Norm.” You might also notice armor listed as “CE”. The letters “CE” are the abbreviation of the French phrase “Conformité Européene” which literally means “European Conformity”. The term initially used was “EC Mark” and it was officially replaced by “CE Marking” in the Directive 93/68/EEC in 1993. “CE Marking” is now used in all EU official documents. All of this has to do with the European motorcycle safety standards. America has unofficially adopted these standards, but they are not required by law for street use. In contrast, to ride a motorcycle in Europe, you have to have protective apparel that meets these standards.
105.5.2
Here’s the “code” for the rating numbering system: Let’s take a rating of “EN1621-2:2014” The numbers following the “EN” are an indication of what the protector is rated for. The “1621” indicates the item is rated for motorcycle use and the “-2” tells us the area of protection. A protector labeled EN1621-1:2012 is going to be for pretty much anywhere but the back. A protector labeled EN1621-2:2014 is going to be for back protection only. There are two levels of CE protection: CE level 1 and CE level 2 protectors. Typically, you only need a CE level 1 for most tracks. However, some more advanced and higher speed track schools or races require CE level 2.
Finally, the “2014” refers to the year when the standard was implemented. The standards have to be reviewed or updated every few years.
Level 1 protectors: The maximum transmitted force must be below 18 kN, and no single value shall exceed 24 kN
Level 2 protectors: The maximum transmitted force must be below 9 kN, and no single value shall exceed 12 kN.
A lesser used rating you may see sometimes included with the EN1621 rating is “EN340:2003.” The “340” is just a general standard that is not specific to a specific sport or job. So when you see both the 340 and 1621 on a piece of armor, the 340 is really pointless because the 1621 already covers all the requirements for the 340.
The important things you want to look for is the CE level 1 or CE level 2. The CE level 2 is going to offer you the best impact protection for your spine. But above all else, the most important thing to look for is the shape and size of the back protector. A CE level 2 back protector is not going to do you any good if you can’t fit it in your jacket or if the pocket is too big and it moves around on you.
105.5.3
Here’s a further breakdown of the general labelling requirements for protective clothing using the EN340 standard:
EN 340:2003 – Protective clothing – General requirements
· Mark identifying the manufacturer
· Product identifying mark
· Size or size range designation
· EN ### – specific Standard number
· Pictogram – for specific hazard protection, plus performance levels, where applicable
· Care labelling. May include a maximum number of cleaning cycles (max ## x)
· Single use PPE to be marked “DO NOT RE-USE”
For the EN1621 standard, the labelling requirements are as follows: EN 1621-1:2012 – Motorcyclists’ protective clothing against mechanical impact. Impact protectors
Type of protector: S – Shoulder E – Elbow H – Hip K – Knee K + L – Knee + Upper and Middle Tibia L – Front of leg below a K protector KP –Knuckle Protection
Plus, an indication of the covered area: A – reduced coverage for specialized applications B – normal coverage EN 1621-2:2014 – Motorcyclists’ protective clothing against mechanical impact. Motorcyclists back protectors
Type of protector: B or FB – Full back protector (central back and scapuae) CB – Central Back L or LB – Lumbar protection only
Performance level 1 or 2 Abrasion resistance level 1 or 2 Impact cut resistance level 1 or 2 Burst strength level 1 or 2 Level 2 is more protective in all cases
89/686/EEC – Personal protective equipment.
