EN 14126:2003 + AC:2004 is a European standard that specifies performance requirements and test methods for protective clothing materials to ensure they provide effective barriers against biological hazards.

This standard applies to single-use or reusable protective clothing.

The AC in +AC:2004 stands for Amendment Correction, referring to minor updates or clarifications that were made to the original 2003 version in 2004 to correct or clarify certain aspects of the standard.

• Type 3B: Protects against pressurized liquid chemicals, preventing penetration and skin contact.
• Type 4B: Shields against liquid saturation, forming a barrier against liquid hazards.
• Type 5B: Guards against airborne solid particulates, blocking contaminated particulates and dust.
• Type 6B: Offers limited protection from liquid mist or splash, suitable for light spray exposure.
