Standards, Part 3: What the standards are good for

The last in the series of posts from my Nov 2013 article on equipment standards. See part 1 and part 2 for the rest.

Now we turn to the big question: Are any of the aspects of the FIE homologation standard (EN13567) actually relevant to our needs in HES? This question is tricky to answer fully, and is one reason I am hoping to get folks interested in better understanding the protective needs of our community. This blog is part of that effort.



 
As mentioned earlier, standards are developed with a specific intended working environment for an item in mind. Based on the CEN standard described in previous sections, I think we can rest assured that most HES applications are quite different than the environment of Olympic fencing (except perhaps the later period point weapons). For starters, most of our longsword and even rapier trainers weigh two to three times what the Olympic fencer’s weapons weigh, and cutting is quite common (as opposed to only with the saber in modern fencing). Further, based on measurements of actual HES trainers the blade stiffness may be three to five times higher than the acceptable range for Olympic fencing (see References 3 & 4).  This is before we even get into things like the possibility of grappling and strikes. Though, to be fair, there is also the fact that not all fencing masks are created equal (EN13567 is a lower limit). Certainly, prices and features vary widely even amongst FIE homologated masks (quick search turns up a price range of $145-$500).

Let’s look at the applicability of the CEN (and therefore FIE) standards based on equipment, and discuss a bit of the current trends in HES:

Body protection (jackets, leg coverings)
Currently, I’d classify the trend in body coverings in HES into 3 categories:
1)   Historical/Historically inspired garments
2)   Modern fencing garments modified based on experience to suit HES
3)   Minimalist (t-shirt, sweats, etc.)

The first two are most common in competitions and fencing. In both cases, the garments can be either homemade, custom produced by a clothing manufacturer or produced commercially. There is a wide variation in the construction of these garments. The last category is mainly present in drilling, in which contact is minimal, or the users are willing to give up some protective qualities. Some groups advocate wearing modern fencing equipment under something more like (1), as a sort of intermediate solution.

For some weapons practiced in HES, such as the smallsword or rapier (largely thrusting weapons, with possibility for cuts), it becomes a pretty straight projection to EN13567 as possibly being sufficient. Those weapons still differ from those that the FIE body coverings are intended to protect against. The flexibility and size of point, for example, are not the same as the weapons used in sport fencing.  Further, the penetrator used in EN13567 is similar to the minimum dimension of a foil (~3mm square with chamfered corners), a rather different cross-section than that of a typical rapier trainer’s blade form (1-3mm x 9-10mm diamond profile).

For other weapons, such as the longsword, arming sword and other primarily cutting weapons used in an ‘unarmored’ context, an extension of EN13567 is a bit less clear. First, as is abundantly obvious to practitioners, modern fencing clothing provides very little in the way of blunt impact energy reduction, especially against the sorts of cuts that may be readily delivered with a 3.5 lb steel longsword trainer. For this reason padded garments are usually preferred, if only to take the edge off most blows and reduce bruising. From a standard standpoint, there is no requirement for energy reduction in FIE homologated garments, only penetration resistance. But penetration resistance is still the more reasonable safety limit to put into place as ‘allowable pain and injury’ from cuts, and even the energy required to cause injury is quite variable. Therefore, EN13567 can act as a good start to developing a penetration resistance standard. Like the rapier compared to the foil above, however, the cutting weapon trainers have a different typical cross-section, varying levels of flexibility, etc., that would need to be accounted for in any newly developed tests or standards.

In Olympic fencing garments, the combination of the jacket collar and the bib of the mask protect the throat, with no rigid defense present or required. However, due to certain techniques in HES that specifically target the throat and neck, as well as the increased stiffness of HES trainers, this is one other area where EN13567 may not be sufficient. In practice, many practitioners wear a rigid, padded or combination defense on the throat and base of the neck. Some even extend to cover portions of the clavicle, sternum and cervical vertebrae. In SCA heavy combat and rapier, there are rules outlining additional neck defenses, the heavier of which requires rigid coverage of the throat and cervical vertebrae. Many HES events, practitioners and schools follow similar rules.

A final important point: in Olympic fencing, not all weapons have the entire body as a target. Typically in HES, all weapons allow strikes to all areas of the body. Therefore, it is prudent to take this aspect into account when considering the applicability of EN13567 to HES equipment. While the protective zones outlined would likely make a suitable minimum, a recommendation for greater coverage would be prudent. Examples of additional coverage would be shin protection or additional protection for the elbows and knees, an area where some organizations, such as the SCA and some HES groups, stipulate hard protection when cutting weapons are being used.

Head/face protection (mask)
Much like the body coverings, there are several trends for head protection in HES:
1)   Historical/Historically inspired full head protection (steel helmets and padded liners with formed steel or perforated plate face protection)
2)   Fencing Masks (with no additions)
3)   Fencing Masks with additional protection added (e.g. padding to the top, back of the head coverage, padded cap under mask, etc.)
4)   Custom/repurposed protection (perforated plate fencing masks, tactical gear, etc.)
5)   No protection or eye/nose protection only.

As with body coverings, there tends to be a wide variety of the particular protection used, but the trends are fairly few. Few groups favor options (2) and  (5) outside of drilling or special conditions fencing (such as that between two highly experienced fencers). Option (4) and (1) gained some traction in the last few years as readily available commercial options that weren’t custom made armor appeared. For option 4, which appears to be the most common arrangement based on event pictures, the base mask is typically a ‘3-weapon’ mask, though not always an FIE homologated one. To the base mask can be added a combination of: a padded cap (coif) under the mask, a ‘coach’s mask protector’ (add-on padding with a cloth or leather outer layer that is slipped onto a regular fencing mask), and some form of back-of-head protection.

For the additional padding added to the standard fencing masks, there is no corresponding portion of EN13567, as the standard requires the mask itself to pass. Further, these protectors are not allowed in FIE competition, so their homologation becomes completely unnecessary. Similarly for the back-of-head protection: these are not something used in sport fencing competition. In other words: we have no standard on which to base our judgment of these items.

For the creation of a rule for back of the head protection, a good start would be the garment penetration requirements of EN13567. The padded covers and coifs, however, would be entirely a new thing for which the only relevant aspects of EN13567 is that the fit is not adversely affected, and that it does not allow the mask to come into contact with the wearer’s face. Much like padding in garments to reduce the impact of blows, a new recommendation based on energy reduction would likely prove useful. This recommendation would also prove useful for padding and suspension systems in the other types of head protection. In the development of a new standard, information from other activities, such as kendo or SCA heavy combat, may be of limited use as the nature of their weapons, targets and strikes differ significantly and therefore the equipment rules may not be entirely relevant to HES.
