PROTECTIVE CLOTHING AGAINST LIQUID CHEMICALS. (TYPE 6 AND PB6 DEVICES). Equivalence with EN 13034:2005+a1:2009.
This standard specifies the minimum requirements for limited-use and reusable chemical protective clothing. The use of chemical protective clothing with limited power is intended for cases where potential exposure to light aerosols or low-volume, low-pressure splashes is possible, where a complete barrier against liquid permeation is not required. It applies to chemical protective suits (type 6) and partial body protection suits (type PB[6]):
PRETREATMENT as directed by the manufacturer or if not indicated 5 cleaning cycles
PRE CONDITIONING AND CONDITIONING according to EN 14325
-Testing and classification according to EN 14325:2004
-For all requirements, performance level 1 must be obtained with the exception of penetration and liquid repellency where a minimum level 3 in repellency must be obtained for at least one of the liquids and level 2 penetration for at least one of the liquids.

SEAMS, JOINTS AND ASSEMBLIES
-The stitching must prevent the penetration of liquids through the stitches or other components of a seam and must not prevent the slippage of the liquid.
-Type 6 suits should also be considered from the result of the spray test of the complete suit.
-Seam strength: according to EN ISO 13935-2, a seam strength of at least class 1 must be obtained.
FEATURES FOR A COMPLETE SUIT
-They must meet the requirements of the EN 13688 standard
-For type 6 garments they must meet the requirements of the “7 movements”:
-Kneel
-Climb the vertical ladder
-Place your hands at chest level
-Kneeling on your right knee
-Extend the arms fully
-Standing with your feet apart
-Kneeling just like movement 4
-For type PB 6 garments, they should not be tested with the light spray test.
-The spray test method based on EN ISO 17491-4 must be modified in some points described in the standard
MARKED
– Type 6 for chemical protective suits and Type PB 6 for partial protection
-Requirements according to EN 13688
-Reusable PPE must be marked with conservation pictograms according to EN 23758.
-For single-use PPE, mark with the warning “Do not reuse”.
