Main Views and Key Information

• Test Standards: Coveralls are tested against ISO 16603, ISO 16604, and EN 14126 standards to ensure resistance to biohazards.
• Performance Metrics:
  • Resistance to blood penetration and blood penetration with virus are critical for biohazard protection.
  • Higher values (e.g., Class 6) are preferred for better performance.
  • Tensile strength, tear resistance, puncture resistance, and abrasion resistance are physical performance indicators.
  • Basis weight reflects the thickness and durability of the material.
• Whole Suit Performance is evaluated to ensure the coverall as a complete unit meets the required safety standards.
• Missing Information is indicated by yellow shaded cells, suggesting that some models may not have full data on all performance criteria.
• Other Brands and Models may also comply with the WHO guidelines, but this list is not exhaustive.

Summary of Recommendations

• Choose coveralls that meet ISO 16603 Class 3 or ISO 16604 Class 2 for biohazard protection.
• Prioritize models with higher performance ratings (e.g., Class 6) for better resistance.
• Consider physical performance metrics such as tensile strength, tear resistance, and abrasion resistance.
• Check the whole suit performance to ensure the coverall is suitable for the intended use.
• Be aware that not all models have complete data, and further evaluation may be necessary for full compliance.
