EN 11495:2018 ELECTROSTATIC PROPERTIES
PART 5: MATERIAL PERFORMANCE AND
• The person wearing the electrostatic dissipative clothing shall be properly
earthed. The resistance between the person’s skin and earth shall be less than
108 Ω e.g. by wearing adequate footwear on dissipative or conductive oors.
• Electrostatic dissipative protective clothing shall not be open or removed whilst
in presence of ammable or explosive atmospheres or while handling ammable
or explosive substances.
• Electrostatic dissipative protective clothing is intended to be worn in Zones 1, 2,
20, 21 and 22 (see EN 60079-10-1  and EN 60079-10-2 ) in which the mini-
mum ignition energy of any explosive atmosphere is not less than 0.016 mJ.
• Electrostatic dissipative protective clothing shall not be used in oxygen enriched
atmospheres, or in zone 0 (see EN 60079-10-1 ) without prior approval of the
responsible safety engineer.
• The electrostatic dissipative performance of the electrostatic dissipative
protective clothing can be aected by wear and tear, laundering and possible
• Electrostatic dissipative protective clothing shall be worn in such a way that it
permanently covers all non-complying materials during normal use (including
• Metals in clothing, for example buttons and threads (used for antistatic eects),
should obviously be avoided. Voltage can be transferred from clothing to the
body, causing an electric shock. Exposed metal buttons must also be avoided as
they can cause short-circuiting.
• When properly earthed, the protective clothing possesses antistatic properties
as per EN 1149-5, and is suitable for use in explosive atmospheres (ATEX) (except
oxygen-enriched ammable atmospheres).
EN 13034+A1:2009 PROTECTION
FROM LIQUID CHEMICALS
• The clothing protects the wearer from a number of dierent chemicals.
EN 13034+A1:2009 tests the following: H
30% class 3/3, NaOH 10% class 3/2,
O-xylène No class, Butanol-l No class.
• The fabric is subjected to the following tests: Dimensional stability; approved,
wear resistance: Class 3, diagonal tear resistance: Class 2: tensile strength:
Class 5, penetrati on test: Class 2.
• Not suitable for use in areas where oxygen content exceeds 21% without the
approval of the safety ocer.
• In case of an accident involving liquid chemicals or ammable liquids, the aect-
ed clothing must be removed immediately and disposed of without coming into
contact with the skin.
• To reactivate the chemical-repellent properties of the fabric (EN13034+A1:2009),
the garments should be re-treated by means of tunnel-nishing or tumble-
drying at 90 °C (see ISO 15797 8A)
• Re-treat after every fth wash with HYDROB FC to meet EN13034+A1:2009
• We recommend that the garments’ protective properties are tested before
re-use to ensure the full level of protection is maintained.

• The environmental conditions and the risks at the working site shall be regarded.
• Deviations from the parameters in this document may result in more severe
• Protective clothing shall be worn in the closed state.
• Protective clothing according to this standard is not intended to be used as
electrical insulating protective clothing and does not provide protection against
• Protective clothing that becomes contaminated with grease, oil or ammable
liquids or combustible materials should not be used.
• Protective clothing that is damaged to the extent that its protective qualities are
impaired (e.g. holes in garment, not functioning closures) should not be used.
• For full body protection suitable additional protective equipment (helmet with
protective face screen, protective gloves, and footwear (boots)) shall be used.
• No garments like shirts, undergarments or underwear made of for example
polyamide, polyester or acrylic bres which melts under arc exposures, should
• The clothing must be stored in a dry, dark and well-ventilated room.
• In the event of tearing or other damage, the clothing must not be repaired by
EN ISO 20471: PROTECTION & CLASSIFICATION
• Several items of Safety+ EN ISO 20471 clothing can be worn together for greater
• A class 3 garment must meet the following: Safety Class 2 top must be worn with
an Safety Class 2 pants or bib-pants with two reectors.
• Safety+ EN ISO 20471 protective clothing is CE-approved and approved in
accordance with EN ISO 20471. The upper gure (X) in the pictogram indicates
its class and the lower gure (Y) refers to its reective value. The class of the
safety clothing indicates the minimum requirements of uorescent and reective
material required on the safety clothing.
• Protection may be reduced when the clothing is dirty.
• See washing instructions for fabric qualities and classication.
