Head injuries are the principal cause of motorbike-related fatalities. Wearing a helmet reduces the need for post-accident hospitalization by 50%. Not wearing helmets increases the probability of suffering serious head injury by 40%
The entire range of LEM products is guaranteed by the European code of standardisation ECE22, the development and implantation of which was made possible by LEM’s collaboration.

In addition, in order to guarantee the quality of its products, LEM carries out a series of quality control tests:
- Required by European regulation ECE22.05, every 3,200 produced units, per model, are subject to routine tests, in addition to the annual audits carried out by the centre of standardisation.
- Volunteer tests for each manufactured batch and for material verification.

I.- External casing
Is the most rigid part:
• Purpose: Spread the energy of the impact over the entire surface so that it does not concentrate in only one area.
• Block any exterior objects from penetrating the helmet and directly impacting the user’s head.
Can consist of thermoplastic materials or compacted fibres with resin.
II.- Internal casing:
• Purpose: absorb the maximum amount of energy of the impact, keeping it from reaching the user’s head
• Material: concave cells of expanded polystyrene (EPS)
• Varying densities are used depending on the part of the helmet. After an impact, they are compressed and stop working adequately, which is why the helmet should be replaced.
III.- Support system:
• Purpose: Should keep the helmet from slipping from the motorist’s head, in case of a fall or impact. Attention: the helmet should always be fastened and well-adjusted.
• Parts: straps, buckles and closing system
• Types of closing systems: double ring, automatic clip and micrometric

IV.- Interior filling:
• Purpose: provide comfort.
• Should provide ventilation and absorb perspiration.
• The most practical: they can be taken apart and are washable.
V- Screen:
• Purpose: protection of eyes and respiratory passages
• Material: polycarbonate, which provides the best flexibility-resistance ratio when impacted.
• In order to be standardised they should offer:
- Scratch-resistant treatment
- Neutral optics
• The Anti-fog system: the use of an anti-fog film allows users to close the screen without it fogging up, resulting in clear vision while blocking water and wind from entering
• Peripheral vision: for safety reasons, the helmet opening near the screen should provide peripheral vision both laterally as well as if the user looks to the rear of the motorbike.

The current European regulation in terms of helmet standardisation is ECE22.05. It is the most commonly followed regulation internationally.
Helmets and screens are subjected to a series of tests in the most extreme of conditions for helmets at – 20 ºC and at + 50 ºC.
Helmets are assigned a letter according to their level of protection.
P: Protective ( Integrated and openable with protective chin strap)
J : Jet ( Open helmet Jets and Demi-jets )
NP: Jet + Non-protective chin strap (Openable with non-protective chin strap).
Every European country has its own centre of standardisation and the country of origin is declared on helmet and screen with the letter E and a number.

Some examples of centres of standardisation:
• E1 Germany
• E2 France
• E3 Italy
• E9 Spain
• E13 Luxemburg
• E21 Portugal

What helmet standardization tags indicate:
b: 05 : Indicates revision of current regulation.
c: 4 consecutive numbers: standardisation number assigned to this helmet.
d: Letters (J – P – N/P) Indicates standardisation depending on level of safety.
e: Production series number: with which production control and trackability are carried out.
