6 2 CE marking What & Why? CE marking
European Regulation 2016/425 – Manufacturing directive
✓ Consists of the CE logo and the four-digit identification number for cat.III. CE on its own is for category I and cat.II.
✓ Indicates that the (technical) product complies with the relevant European health, safety and environmental protection legislation.
✓ Is the prerequisite for marketing the product within the EU.
8 CE marking - only one correct symbol
“Conformité Européenne“ “China Export“
9 What does CE marking involve for the manufacturer?
To carry the CE-mark, Chemical Protective Clothing (cat.III) must: ➜ Pass one or more of the garment “Type” tests
➜ Meet or exceed minimum requirements for the materials’ physical and chemical properties
➜ Be correctly identified and labeled
➜ Fulfill the basic safety and health requirements for PPE
➜ Be audited by a quality audit system
➜ It is a guarantee for quality PPE
10 Consequences of non-certified PPE
Using an uncertified or fake PPE can be risky:
➜ Substandard quality
➜ PPE gets damaged during use
➜ Fake PPE gives the illusion of safety
➜ Insufficient protection of the worker
➜ Employer is liable
➜ Serious risk of injury

21 Type 3 test for protective garments
22 Type 4 test for protective garments
Measurement of tightness
✓ Test according to EN ISO 17491-4 (Method B) Respiratory air supply ✓ Test object: garment ✓ Duration: 1 minute Test chamber ✓ Test liquid: colored water (methyl blue) Nozzles ✓ Test conditions: liquid spray at a pressure Detector garment is of 3 bar (nozzle pressure) at a distance worn under protective of 1 meter (1.14 +/-0.1l/min per nozzle garment being tested of test liquid (4.16-4.96 litres)) ✓ Pass criteria: stained area on detector garment < 3x calibration stain(25 +/-5µl test liquid minimum surface area 1cm2) Rotating platform
23 Type 5 test for protective garments
Measurement of penetration Total NaCl in cabin resistance
✓ Test according to EN ISO 13982-2 ✓ Test object: garment ✓ Duration: approx. 9 minutes per garment tested ✓ Test conditions on 10 garments: • 3 min standing per test point • 3 min walking per test point • 3 min squatting per test point
Flame photometer ✓ Pass LS,8/10 ≤ 15% for 8 out of 10 mean values and Ljmn,82/90 ≤ 30% for 82 out of 90 indiv. values
24 Type 6 test for protective suits
Low level spray test EN ISO 17491-4, method A ✓ Test liquid: coloured water (methyl blue) Respiratory air supply ✓ Surface tension : 52±7.5 x 10-3 N/m Test chamber ✓ Quantity of liquid sprayed : 0.47±0.05 l/min per
nozzle of test liquid (1.68-2.08 litres) Nozzles ✓ Test Conditions :Liquid spray at a pressure of 3 bar Detector garment is nozzle pressure at a distance of 1 meter. worn under protective ✓ Test Duration :1 minute . Plus two minutes to garment being tested allow liquid to drain off surface before removing test garment ✓ Pass criteria : stained area on detector garment < 3x calibration stain(25 +/-5µl test liquid minimum Rotating platform surface area 1cm2)
25 EN 14126 biobarrier
The material used in clothing to protect against hazardous biological substances is in compliance with EN 14126.
Resistance to the following is tested: • Bacteria • Viruses • Biological aerosols • Contaminated dust Covid-19, SARS, MERS • Penetration with artificial blood
The classification of the infection protection garments corresponds to the types defined for chemical protection garments (e.g. Type 3-B or Type 6-B)
Ebola 26 3 Take Aways
1 | CE regulation defines 3 categories for PPE according to the risk they protect against
2 | Inside the chemical protection garments standard are 6 types based on the state of the chemicals
3 | The cabin tests are based on the types and have their limitations
