CE Standard (EU)

Protective clothing is designed to resist various hazardous situations, which includes exclusively the risks that may cause very serious consequences such as death or irreversible damage to health.

And based on different proteciton level, the protective clothing against chemicals are categaried by different types, and also have mutiple standards helping people to select the proper garment for protection.

Determination of resistance to penetration by a jet of liquid

• Fabric, seams and joints being tested with intense and pressurized liquid jet
• Low surface tension of liquid jets
• Requires coveralls with fully sealed seam
• One nozzle sprays at potential weak areas of coverall including chinstrap, crotch, zipper flap and joints

Determination of resistance to penetration by liquid spray

• 4 nozzles with general overspray of liquid without penetration on coverall
• Low surface tension of liquid sprays being tested on whole garment to experiment saturation of fabric
  
• Fabric, seams and joints being tested without pressurized liquid

Determination of inward leakage of aerosols & solid particles

• Spray cabin filled with dust
• The test is performed by real person, aims to simulate daily use
  
• Subject (real person) performs 3 exercises on treadmill
  
• Particle inward leakage(IL) and total inward leakage(TIL) must meet test requirements

Determination of resistance to penetration by reduced liquid spray

• 4 nozzles with general overspray of liquid without penetration on coverall
  
• Low surface tension of liquid sprays being tested on whole garment to experiment saturation of fabric
  
• Fabric, seams and joints being tested without pressurized liquid
  
• About 40% of the liquid spray is loaded onto the suit compared with Type 4 test

Determination of inward leakage of aerosols & solid particles

• The standard was developed to be applied in nuclear industry without protection against ionizing radiation
  
• The test follows the same protocols as Type 5 test with different judgement criteria
  
• 3 classifications indicate different protection level

To check whether the fabric/materials burn while contacting heat source. Whether the fabric stops flame spreading if burned

• Requirements for limited flame spread Index 1 including no spreading of the flame, no flaming debris, no afterglow, a hole may be formed.

The standard specifies a set of requirements and test methods to measure the fabric protection against infective agents ISO 16603, ISO 16604, ISO/DIS 22611 determines penetration by blood, body fluids, blood borne and biologically contaminated aerosol ISO 22612, ISO 22610 determines the resistance of dry and wet microbial penetration.

• The standard specifies a set of requirements and test methods to measure the fabric protection against static electricity or charge decay
  
• Electrostatic resistance is required when the wearer is exposed to environments where sparks could cause explosions or ignition
  
• Coveralls according to this standard do not offer protection from main voltages

• The test standard covers requirements in chemical penetration, fabric strength and ergonomics
  
• The certification includes EN 14786, which simulates liquid spray of drugs
  
• Five different pesticides including U46-D-Fluid (BASF), Pirimor Granulat (Syngenta), Amistar(Syngenta), Betanal Expert(Bayer), Folicur(Bayer) are tested to ensure protection against pesticides
