** We recommend performing what is known as the „crackling test" on helmets made of non glass fibre reinforced thermoplastic to
get a rough idea as to a helmet's state of embrittlement. To do this, lightly press the helmet shell inwards on the sides or slightly
bend the peak. If you hear a crackling or cracking sound with your ear pressed against the shell, do not use the helmet again.
In this case the safety helmet should no longer be used and should be destroyed. SCHUBERTH helmets of thermoplastic
material should be used for no more than 4 years. When defining the usable life of your helmets, make sure you
observe the relevant regulations that apply in the country in which the helmet is used and also recommendations of
responsible institutions on the usable life of safety helmets.
Notes on use
Correct handling of the safety helmet is essential to ensure that it functions perfectly. Check the helmet shell and
interior fitments regularly. If you find any damage, you should replace the helmet. After a heavy impact, the safety
helmet should no longer be used. This applies even if the safety helmet shows no visible damage. Electrically
insulating helmets should not be used on their own, but instead in conjunction with other, compatible PPE (personal
protective equipment) that is suited for protecting against the risks involved in the work in question. Before use, check
that your helmet's protection class is adequate for coping with the nominal voltage that is likely to be encountered
during the work in question. Insulating helmets should not be exposed to situations that entail the risk of a partial
reduction in the insulating properties. If the helmet has become dirty or soiled (oil, tar, paint, etc.) then it must
be cleaned carefully on the outside, particularly on the outside surface, in accordance with the manufacturer's
recommendations.
Warranty
SCHUBERTH offers the original purchaser a warranty against material and manufacturing defects of 2 (two) years from
the purchase date, provided that the helmet is used as directed. SCHUBERTH shall only assume limited liability, at
their own discretion, for either the repair or replacement of products which have been proven to be faulty within the
warranty period. The helmet must not have been modified and/or damaged through improper use.
Storage and transport
Safety helmets should be stored in a safe place under cool and dry conditions. Do not store the helmet in direct
sunlight. The helmet can be transported in its original carton provided it is adequately wrapped in packing paper.
Electrically insulating helmets should not be stored where it is under any pressure, compressed, or near any heat
source. We recommend a storage temperature of between around 20 ±15°C.
Applications and versions of safety helmets and their codes
All safety helmets are marked with their date of manufacture, code of the material used, type, size and codes for
additional safety requirements:
Explanation of material codes
Thermoplastic helmet shell material:
ABS = Helmet shell of acrylonitrile-butadiene-styrene copolymer
(HD)PE = Helmet shell of (high-pressure) polyethylene
The codes for the helmet shell material are located under the peak.
Explanation of codes for additional safety requirements:
Very low temperature (in accordance with DIN EN 397)
-20° C = helmet for use in low temperatures (e.g. outdoors in severe cold)
-30° C = helmet for use in cold stores, for example
Very high temperature (in accordance with DIN EN 397)
Safety helmet intended for use in high ambient temperatures (e.g. furnace work).
Electrical insulation (in accordance with DIN EN 397)
Helmet intended to protect the wearer from brief unintentional contact with a conductor
carrying an a.c. voltage of up to 440 volts.
Molten metal (in accordance with DIN EN 397)
Helmet intended for use involving molten metal (e.g. foundry work).
Lateral deformation (as per DIN EN 397)
Greater lateral rigidity.
Electrical insulation for work on low-voltage plant systems (as per DIN EN 50365)
Helmet designed for use in work under voltage or in the vicinity of parts under voltage of up
to AC 1000 V or DC 1500 V.
Forestry version (as per withdrawn standard DIN EN 4840)
