Test Methods

Test methods and protocols to measure the mechanical and physical performance characteristics of the materials used to construct ChemDefend® coveralls as defined in EN14325:2004 in connection with Type 5 EN ISO 13982-1+A1:2010, Type 6 EN ISO 13034+A1:2009 and Type 3 and 4 EN 14605+A1:2009.

TESTS INCLUDE

• Abrasion Resistance EN530:2010 Method 2
• Flex Cracking EN ISO 7854:1997 Method B
• Trapezoidal Tear EN ISO 9073-4: 1997
• Tensile strength EN ISO 13934-1:1999
• Puncture Resistance EN 863:1995

Test methods and protocols relating to the mechanical and physical performance characteristics of the materials used to construct ChemDefend® coveralls but not defined in EN14325:2004. However, these characteristics and data assist in the selection of coveralls, appropriate to a particular hazard or set of working conditions.

TESTS INCLUDE

• Resistance to Blocking ISO 25978:1990
• Resistance to water penetration EN ISO 20811:1992
• Electrostatic Dissipative Properties EN1149-5:2008 to include:
  • Determination of Surface Resistivity EN1149-1:2006
  • Determination of Induction Decay Time EN1149-3:2004

Whole Suit tests overview and description of the test methods as defined in Type 5 EN ISO 13982-1:2004+A1:2010, Type 6 EN ISO 13034:2005+A1:2009 and Type 3 and 4 EN 14605+A1:2009.

• EN ISO 17491-3:2008 – TYPE 3 - liquid tight protective clothing - suits which can protect against strong and directional jets of a liquid chemical. Fabric and seams must also pass chemical permeation test according to EN ISO 6529 or EN374-3 against 2 test chemicals.
• EN ISO 17491-4:2008, method B TYPE 4- spray tight protective clothing - suits which can protect against saturation of liquid chemicals where volume of the liquid builds up on the suit, causing pools and rivulets. Fabric and seams must also pass the chemical permeation test according to EN ISO 6529 or EN374-3.
• EN13982-1(&2) – Type 5 - protection against solid particulates - suits for protection against hazardous dusts and dry particles.
• EN ISO 17491-4:2008 method A TYPE 6- reduced spray protection - suits for protection against light spray and splashes of liquid chemicals where there is no directional spray or build up of liquid on the suit. Fabric must pass the EN 368 or EN ISO 6530 “Gutter Test”.

Description of the EN6530 test to assess the liquid repellence and liquid penetration of materials used to construct ChemDefend® coveralls.

TESTS INCLUDE

• Fabric repellence to 30% sulphuric acid, 10% sodium hydroxide, o-xylene and butan-1-ol.
• Fabric resistance to penetration measured with 30% sulphuric acid, 10% sodium hydroxide, o-xylene and butan-1-ol.

Permeation is a process by which, at a molecular level, a solid liquid or gaseous chemical passes through a protective material.

The following test methods used to measure chemical permeation are described and defined:

• Permeation Rate - PR
• Steady State Permeation Rate - SSPR
• Minimum Detectable Permeation Rate – MDPR
• Breakthrough Detection Time – BDT
• Normalised Breakthrough time according to ASTM F379 and EN 374-3

Describes the test methods to measure the barrier properties to infective agents such as virus, bacteria and blood borne pathogens, of materials used to manufacture ChemDefend® coveralls.

The following test methods are described:

• Penetration test using synthetic blood (ISO/FDIS 16603)
• Resistance to penetration by viruses (ISO/FDIS 16604)
• Resistance to penetration by bacteria (ISO/DIS 22610)
• Resistance to penetration by biologically contaminated aerosols (ISO/DIS 22611)
• Resistance to penetration by contaminated dust (ISO/DIS 22612)

Requirement of none ventilated protective clothing against particulate radioactive material.
