Is EN 455-2 force at break requirement too high?

Too high?Too low?
Harmonization of EN and ISO standards
EN and ISO standards are far apart, with the ISO standard requirements for physical properties well below those of EN
Harmonization of ISO and EN standards on medical gloves could provide some rationalization of the current disparate standards
The Vienna Agreement signed between CEN and ISO in 1991 promotes cooperation between CEN and ISO
A consensus global standard could only be achieved through the work of the Global Harmonization Task Force (GHTF)
The SMG scheme is a voluntary third party product certification scheme for NR examination gloves, both powdered and powder-free
The SMG specification establishes requirements for:
Freedom from holes
Physical properties
Protein content
Powder content
The scheme is operated by the Malaysian Rubber Board, an ISO/IEC Guide 65 body, authorized by Standards Malaysia
The rigorous certification procedure offers the assurance that SMG gloves comply with the requirements of the SMG specification

EN455-3 requires monitoring of
process limit of leachable protein.
EN455-3 considers gloves containing
more than 2 mg of powder as
powdered gloves.
Protein and powder limits of SMG gloves
• Malaysia is the world’s leading exporter of medical gloves
• The many standards that are applicable lead to higher cost to both Malaysian producers and importers/users of Malaysian gloves
• SMG examination gloves are certified for compliance with the EN, ASTM and ISO standards
