This ensures the extra safety that our customers – rightly – expect from us. DIN EN 397 – Protection from falling objects ---------------------------------------------- Industrial safety helmets from uvex comply with standard DIN EN 397, which states that they must be designed to protect the wearer from falling objects. Protection against mechanical impacts to the head safeguards the user against possible consequences such as brain injuries or skull fractures. The standard also includes protection against lateral deformation of the helmet, as well as protecting the wearer from dangerous head injuries. Industrial safety helmets that comply with standard DIN EN 397 generally meet the following safety requirements: | Binding requirements | optional requirements | |---|---| | **All helmets certified according to EN 397 must meet these requirements.** | **A helmet certified in accordance with EN 397 may meet these requirements; they are, however, not mandatory requirements.** | | shock absorption, vertical | very low temperatures (-20 °C or -30 °C) | | penetration resistance (against sharp and pointed objects) | very high temperatures (+150 °C) | | flame resistance | electrical insulation (440 V) | | chin strap attachment: chin strap releases at minimum 150N and maximum 250 N | molten metal (MM) | | | lateral deformation | ### Model overview ![](https://d3rbxgeqn1ye9j.cloudfront.net/images/rDdhyc2dPPgGhmgcXPuNRI_oOhl0JKgdqI4YDJ_lpL4/w:345/h:221/fn:Y3NtX2VuLTM5Ny1oZWFkLXByb3RlY3Rpb24tc2FmZXR5LWhlbG1ldHMtb3ZlcnZpZXctdXZleC0yMDI0X2ExMjdjNmI5ZGE:t/cb:8e116f710966505cf182660483933aaaac469e89/el:1/fq:jpeg:85:avif:70:webp:80/aHR0cHM6Ly9kM3JieGdlcW4xeWU5ai5jbG91ZGZyb250Lm5ldC9maWxlYWRtaW4vd3d3LnV2ZXgtc2FmZXR5LmNvbS9Lbm93bGVkZ2Uvc2FmZXR5X3N0YW5kYXJkcy9lbi0zOTctaGVhZC1wcm90ZWN0aW9uLXNhZmV0eS1oZWxtZXRzLW92ZXJ2aWV3LXV2ZXgtMjAyNC5qcGc_MTcxMzg3NzgwMg) ![](https://d3rbxgeqn1ye9j.cloudfront.net/images/2WHQly_Nz8nNB1zh59xVIqRKDJSWKktSao3RnCVa3lE/w:537/h:537/fn:Y3NtX3NhZmV0eV9zdGFuZGFyZHNfaGVhZF9kaW5fZW5fMzk3X2FmMzIxM2E3NTI:t/cb:f2274aaf476335381da4f8771bb2fa685dfde306/el:1/fq:jpeg:85:avif:70:webp:80/c:915:915:fp:0.5:0.54656533526553/rt:force/aHR0cHM6Ly9kM3JieGdlcW4xeWU5ai5jbG91ZGZyb250Lm5ldC9maWxlYWRtaW4vd3d3LnV2ZXgtc2FmZXR5LmNvbS9Lbm93bGVkZ2Uvc2FmZXR5X3N0YW5kYXJkcy9zYWZldHlfc3RhbmRhcmRzX2hlYWRfZGluX2VuXzM5Ny5qcGc_MTQ3MzMyODM3Ng) [DIN EN 397-certified head protection from uvex](https://www.uvex-safety.com/en/products/safety-helmets/?smxfilter=1&f=613) EN 50365 – Insulating helmets for use on low voltage installations -------------------------------------------------------------------- ### Protection against electric shocks and prevention of dangerous electric current passing through the head **Requirements:** - All helmets must also meet the requirements in accordance with EN 397. - Protection against alternating voltage of up to 1000 V (AC) or direct voltage up to 1500 V (DC) - Insulating helmets must not contain any conductive parts. - Air vents (if available) must not allow any accidental contact with live parts.
