Kamikadze-Ace> kolena atd. tj. velky kosti neresim, mam od nich chranice vseho a jsou vazne dobry, ale ty pateraky level 1, tj. pet let zpatky
btw. en 1621-1 je pro ochranu velkych kosti, tj. ramena, kolena atd.
en 1621-2 je pro pateraky, ktery ma L1 a L2
1621-1 zadnej L1 a L2 nema

pokud by meli zajem zustat na spici delaji pateraky s impact faktorem 4KN, coz je kriticka hodnota pro pater a mozna tak za pet let az se prodaji vsechny L1 ze vsech skladu vsech firem na svete i en 1621-2 L3,

Attempts to reduce the transmitted force requirement to 4 kN and to correspondingly reduce the 50 Joule impact energy requirement were strongly resisted by industry, who claimed consumers would be confused by different impact energy requirements between EN1621-1 and EN1621-2.
In truth, it was in the industry's commercial interests to test both types of protector at 50J, since they could then extol the efficacy of back protectors which, when struck with the same impact energy as limb protectors, transmitted only 9 or 18 kN compared to 35 kN. The consumer would be unaware that subtle differences in the impactor and anvil were responsible, and still less aware that 9 kN was still more than double the safe limit supported by medical experts. Furthermore, during the late 1990s, some companies had used the wholly inappropriate EN 1621-1 to CE mark their back protectors. Commercial objectives were given priority over consumer safety.
