IEC 60601-1-11:2015 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document. IEC 60601-1-11:2015 applies to the basic safety and essential performance of medical electrical equipment and medical electrical systems for use in the home healthcare environment. It applies regardless of whether the medical electrical equipment or medical electrical system is intended for use by a lay operator or by trained healthcare personnel. The home healthcare environment includes: - the dwelling place in which a patient lives; - other places where patients are present both indoors and outdoors, excluding professional healthcare facility environments where operators with medical training are continually available when patients are present. This second edition cancels and replaces the first edition of IEC 60601-1-11, published in 2010, and constitutes a technical revision. The most significant changes with respect to the previous edition include the following modifications: - correction of test method for relative humidity control at temperatures above 35 °C; - redrafting of subclauses that altered instead of adding to the general standard or other collateral standards; and - harmonizing with the changes to the amendments to the general standard and other collateral standards.
