The norms allow for a maximum of 275 g in any direction (for Snell – 300 g in the direction of the accelerometer settings). Further check the availability of different projections, rubber-like coating, flares and accessories. They should not obstruct the sliding of the helmet on the asphalt to eliminate the possibility of additional shocks falling into the potholes. A special device t hat to cover, reminiscent of sandpaper, and measures the rotational speed, which can cause potential harm. All tests are performed and with the integrals and with helmets with visors lift, which under no circumstances it should not open itself. Otherwise, the test will not be passed. Strap is tested separately: pre-load is pulled in the 30 kg (with strap should not stretch more than 35 mm), then an additional suspended load to 10 kg and dropped from a height of 75 cm, simulating the harsh burden on the break.

Permanent deformation should not exceed 25 mm. Straps with buckles, consisting of two metal rings, Recycle at break, after which the device must. Self-discovery and displacement of the strap fastener systems length adjustment is not allowed. Visor helmets must meet the requirements for the passage of ultraviolet rays, remain transparent and flexible at temperatures down to -20 C and withstand without failure impact test: the fall of the hammer weight pointed to three kilograms meter height. Other tests related to resistance to the abrasive effects, refraction (bending of the image), an adequate perception of red marks, yellow and blue. In our opinion, ECE standards are more realistic than Snell. Striving for perfection is infinite, and the technique will certainly become more complicated and cluttered with new requirements.

For example, based on measurements rotational acceleration of the head (as in car tests). And, of course, ventilation systems, such as medical tests prove that the increase in temperature of the head affects the reaction time and concentration. Today does not provide for ease of control helmet with glasses. Perhaps in the future will be measured and calculated as these aspects. As you can see, the current homologation ECE – not "for show", and only approved in this way can be considered a full copy protection. No matter how great the temptation to buy a helmet without the letter "E" in a circle, seduced by a ridiculous price or an interesting design in the style of Nazi helmets horns.
