Protection against liquid chemicals
EN 13034:2005 Clothing for protection against liquid chemicals – Requirements for clothing that gives limited protection against liquid chemicals (Type 6 clothing)
This standard specifies the requirements and test methods for type 6 chemical protection suits for one-off and multiple use. For related accessories, such as gloves and boots, which are not an integral part of the suit, see the corresponding product standards.
The contents of this standard
The fabric is tested in various ways to determine its tensile strength and resistance to chemicals. In these tests, 4 solutions of chemicals (H2SO4 30%, NaOH 10%, o-xylene en butan-1-ol) are applied to a fabric sample. The quantities of liquid that drip off and that penetrate the fabric are determined and must be within the tolerances set in the standard.
One finished product (of each quality) must also be analysed in a so-called mannequin test. During this (spray) test, the wearer must perform 7 movements (described in the standard); the permeability of the garment to liquid chemicals is subsequently determined. The classes attained in the various tests must be listed in the user instructions.
Spray-testing models is not required for “type [PB6 ]” clothing (that provides partial body protection). This does not, however, include overalls. Van Puijenbroek clothing is always type 6. Other requirements in 13034 concern: wear resistance, tear strength, tensile strength and seam strength.
The requirements set in this standard
- Clothing must meet the requirements stipulated in EN 340
- Clothing covered by this standard must pass the spray tes
- In the design, attention must be paid to preventing spatters from penetrating the clothing (via e.g. pocket fastenings, etc.). The requirements specified in EN ISO 11611 (welder's clothing) serve as basis for this.
