European foreword
This document (prEN 455-5:2023) has been prepared by Technical Committee CEN/TC 205 “Non-active
medical devices”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral
part of this document.
EN 455 consists of the following parts under the general title “Medical gloves for single use”:
— Part 1: Requirements and testing for freedom from holes;
— Part 2: Requirements and testing for physical properties;
— Part 3: Requirements and testing for biological evaluation;

Introduction
Adverse reactions to residual chemicals present in medical gloves have been reported over many years
in variable rates of prevalence. These chemicals are part of the manufacturing process including but not
limited to accelerators, activators, antioxidants, or donning aids. Reactions range from dermal irritation
to contact dermatitis including type IV allergic responses. These effects are localised to the area of
contact with the offending chemicals and unlike type I allergic reactions do not show any systemic non-
localised effects. Though they are potentially career altering, they do not escalate to more serious life-
threatening responses.
Such adverse reactions are possible with gloves made of any material whose manufacture involves use
of chemical additives at any stage of the manufacturing process. Factors which contribute to the risk of
reaction include
— the concentration and ease
