 |
The 'Low Chemical Resistant' pictogram is used for those gloves that do not achieve a breakthrough time of at least 30 minutes against at least three chemicals from the defined list, but which comply with the Penetration test. |
 |
The 'Micro-organism' pictogram is to be used when the glove offers protection against bacteria and fungi. If VIRUS appears below the pictogram, the glove offers protection against bacteria, fungi and viruses. | |

| OTHER STANDARDS & DEFINITIONS | |
 |
The international symbol for 'food safe' identifies that the material used in the product is safe for food contact, used in North America, Europe and parts of Asia. |
| EN 455 (Parts 1, 2, 3, 4) |
This standard specifies requirements and tests for single use medical gloves for medical purpose. This includes tests to assess the freedom from holes which is based on a penetration resistance test (similar to EN 374 Part 2), tests to assess the dimensions of the gloves and the mechanical strength of its materials, both before and after an ageing process. |

| ASTM D6319 | Standard specification for dimensions, tolerances and physical requirements for nitrile examination gloves. |
Disclaimer:
Gloves that provide cut or puncture resistance are not cut or puncture proof and do not completely eliminate the potential for cuts or punctures. Cut resistant gloves are not intended to provide protection against powered blades, serrated or other sharp or rotating equipment. Gloves that provide abrasion resistance do not completely eliminate the potential for abrasion-related injuries. Gloves that provide chemical resistance do not completely eliminate the potential for injury due to chemical exposure. It is the responsibility of companies to undertake their own testing and research to ensure that protection equipment is suitable for a particular application and their specific work environment.
