BS EN 13034: 2005 – Type 6 Protective Clothing Protective clothing against liquid chemicals

Performance requirements for chemical protective clothing offering limited protective performance against liquid chemicals 

(type 6 and type PB [6] equipment)

· Products must comply with EN340: 2003

This standard sets out the general requirements for protective clothing i.e. materials shall not be known to cause skin irritation

 or have any adverse effect to health. This also details garment sizing, labelling etc.

Test Requirements for Materials (fabric)

Materials for Type 6 clothing are tested for the following properties;

EN14325: 2004 details the test methods & performance classification of chemical protection clothing materials, seams, joins and assemblages.

EN368 has been replaced by ISO 6530:2005, although it has not yet been harmonised with the European normsTest requirements for seams, 

joins & assemblages of Type 6 protective clothingSeams should be constructed to minimise of prevent penetration of liquid

 through stitch holes or other components of a seam. Seam strength is determined and classified in accordance with EN14325:

2004, Clause 5.5 and must obtain at least Class 1 (>30N). The test method specified in clause 5.5 is EN ISO 13935-2

BS EN368: 1993 - “Gutter Test” - Protective clothing. Protection against liquid chemicals. Test method: resistance 

of materials to penetration by liquidsLiquid chemical penetration is a physical process whereby a liquid penetrates a fabric by 

passing through pores or holes in the fabric. The European standard EN368 (often referred to as the gutter test) measures liquid

penetration through a fabric and liquid repellency by a fabric. Table B shows the standard chemicals used for penetration and 

repellency testing according to EN368;

The test is performed by placing the fabric to be tested in a gutter, inclined at 45º, which is lined with an absorbent fabric; 

10ml of the pre-determined liquid chemical is then poured in within 10 seconds on to the top of the test fabric via a nozzle. 

When testing in accordance with EN368 for repellence to liquid chemicals the material is classified according to the Table

 C for each chemical tested;
