Sterile examination gloves are class I sterile medical devices designed for short non-invasive aseptic procedures (generally less than 60 min) in patient care.

It deals with gloves worn primarily for the protection of the pa

44、tient and glove user from biological cross contamination.NOTE Gloves worn specifically for the protection of the glove user from e.g. chemical and biological hazards are covered by the EU-Directive on Personal Protective Equipment (PPE) and the related standards e.g. EN 16523-1, EN 374-2, EN 374-4,

45、EN ISO 374-1 and EN ISO 374-5.This document describes the rationale behind the requirements of the EN 455 series and explores the possible trade-offs in glove selection between the various factors which affect glove, physical properties, biocompatibility, comfort and sensitivity. The strengths and w

46、eaknesses of various alternative glove materials and the potential biological hazards presented by their use are also explored.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
