4. Changes at a Glance NEW MARKS & REQUIREMENTS Micro-organism Pictograms The pictogram on the left previously related to bacteria and fungi. The new standard calls for a new viral penetration test. If a glove passes this extra test, the word, “Virus” will be added under the Micro-organism pictogram. © 2016 Ansell Limited.

Ansell assumes no responsibility for the suitability or adequacy of an end user’s selection of gloves for a specific application. The beaker icon (low chemical resistance / waterproof) has been eliminated. Dangerous Chemical Pictograms Gloves can only claim protection against Chemical Risks when: - Type C, B or A performance is achieved using the permeation test method EN16523-1:2015 (summarized here) - The glove is leakage proof following testing using the EN374-2:2014 method - Degradation performance for claimed chemicals is available through the information supplied by a manufacturer At least Level 1 performance (more than 10 minutes) against at least one chemical on the list At least Level 2 performance (more than 30 minutes) against at least three chemicals on the list At least Level 2 performance (more than 30 minutes) against at least six chemicals on the list

1. EN 374 + ANSELL: REGULATORY UPDATE OCTOBER 2016 well INFORMED well PROTECTED well AHEAD EN REGULATIONS FOR DANGEROUS CHEMICALS AND MICRO-ORGANISMS ARE CHANGING. LET ANSELL BE YOUR GUIDE. The new EN374 chemical and micro-organism protection guidelines have updated directives that were over 10 years old. Ansell is developing a series of materials to help explain what elements in the standard have changed, why it matters, and what compliance will require.

2. EN374 STANDARD: 2016 CHANGES Official EN ISO 374:2016 standard to be published upon official availability. Changes at a Glance The new EN ISO 374 standard refines the required capabilities for gloves that protect workers whose hands are subject to chemical and/or micro-organism exposure. This summary highlights changes to the EN374 standard. The requirements are described in more detail in the Ansell EN Guide available at: www.ansell.com/enresourcecenter NEW NOMENCLATURE NEW STANDARDS AGREEMENT old EN374: 2003 Gloves giving protection from chemicals and micro-organisms. new EN ISO 374: 2016* Gloves giving protection from dangerous chemicals and micro-organisms. * Official EN ISO 374:2016 standard to be published upon official availability. old EN Created by the European Committee for Standardization (CEN), applicable in Europe and selective affiliate countries (e.g., Australia). old ISO Created by the International Standards Organization; generally accepted if it complies with local regulations; subject to PPE directives in Europe. old EN374 new EN ISO Created cooperatively by ISO or CEN under the Vienna agreement; applicable in Europe and all countries that accept ISO; the defacto standard when Europe adopts it as an ISO standard. new EN ISO 374

3. NEW TESTS old EN374-3:2003 PERMEATION new EN ISO 374:2016* / EN 16523-1:2015 Scoring: 3 specimens taken from the palm are tested for breakthrough times and the lowest is the result; the performance level is correlated with the breakthrough time table. Cuffs: Gloves with long cuffs greater or equal to 400mm are also to be tested with samples taken at 80mm from end of cuff. Chemicals Tested: The chemical permeation table now includes 6 new categories labeled M through T. M Nitric acid 65% 7697-37-2 Inorganic mineral acid, oxidizing N Acetic acid 99% 64-19-7 Organic acid O Ammonia 25% 1336-21-6 Mineral base P Hydrogen peroxide 30% 7722-84-1 Peroxide S Hydrofluoric acid 40% 7664-39-3 Inorganic mineral acid T Formaldehyde 37% 50-00-0 Aldehyde new EN374-4:2013 These are new test methods considering the glove before and after a contact with the chemical. - Normative: Puncture Degradation Resistance test (as per the EN388 test for puncture resistance) - Informative: Weight Change test The results are reported in Instruction for Use as percentage of change due to degradation in perforation test. old DEGRADATION No standard in place. new EN ISO 374-5:2016 Protection against bacteria and fungi. old EN ISO 374-1:2003 MICRO-ORGANISMS Micro-organism requirements previously defined under the EN374-1 standard. new EN ISO 374-5:2016* + ISO16604 / Method B: Protection against bacteria, fungi and virus is now supported with a new pictogram. * Official EN ISO 374:2016 standard to be published upon official availability. Scoring: 3 specimens taken from the palm or the weakest area are tested for breakthrough times and the lowest is the result. Cuffs: No standard for cuff testing. Chemicals Tested: The original list includes 12 chemicals labeled A through L.
