Proteomic Identification Principles for Fine Animal Fiber Verification
LC-MS/MS tryptic peptide analysis provides species-specific verification of fine animal fibers, overriding optical scale degradation in processed blends.
EN 16805
Safety Standard
European technical specifications define the rigorous material and structural requirements for underwater protective face gear. Under the provisions of en 16805, manufacturers must test diving masks for mechanical strength, lens impact resistance and leak prevention. This standard governs the safety of both recreational and professional protective apparel used in marine environments.
Material Performance
The silicone or elastomer skirts and securing straps must withstand degradation from saltwater and temperature extremes. Compliance with en 16805 ensures that the materials do not cause skin irritation or lose their elasticity over time. This requirement protects the wearer from gear failure during critical diving operations.
Pressure Resistance
Testing procedures involve applying physical loads to the mask frame and subjecting the assembly to simulated depth pressures. The seal must maintain its integrity without leaking or cracking under stress. Technical buyers and quality inspectors use these standardized test protocols to evaluate batches before they are released to the retail market.
Any sample that fails to meet these criteria leads to the rejection of the entire manufacturing lot to ensure consumer safety.
Compliance Outcome
Certified test reports demonstrate that the masks meet all criteria for mechanical and material robustness. Adherence to en 16805 is required for affixing the CE mark to protective marine gear sold in Europe.
