IEC 60601-1:2005+Amendment 1:2012, 1.1 is replaced by: This particular standard specifies requirements for the BASIC SAFETY and ESSENTIAL PERFORMANCE of an OXYGEN CONCENTRATOR in combination with its ACCESSORIES, hereafter referred to as ME EQUIPMENT, intended to increase the oxygen concentration of gas intended to be delivered to a single PATIENT. Such OXYGEN CONCENTRATORS are typically intended for use in the HOME HEALTHCARE ENVIRONMENT, including TRANSIT OPERABLE use by a single PATIENT in various environments including any private and public transportation as well as in commercial aircraft. NOTE 1 Such an OXYGEN CONCENTRATOR can also be used in professional health care facilities. This particular standard is applicable to a TRANSIT‐OPERABLE and non‐TRANSIT‐OPERABLE OXYGEN CONCENTRATOR. This particular standard is applicable to an OXYGEN CONCENTRATOR integrated into or used with other medical devices, ME EQUIPMENT or ME SYSTEMS. EXAMPLE 1 An OXYGEN CONCENTRATOR with integrated oxygen CONSERVING EQUIPMENT [10] or humidifier [4]. EXAMPLE 2 An OXYGEN CONCENTRATOR used with a flowmeter stand. EXAMPLE 3 An OXYGEN CONCENTRATOR as part of an anaesthetic system for use in areas with limited logistical supplies of electricity and anaesthetic gases. [3] EXAMPLE 4 An OXYGEN CONCENTRATOR with an integrated liquid reservoir or gas cylinder filling system. This particular standard is also applicable to those ACCESSORIES intended by their MANUFACTURER to be connected to an OXYGEN CONCENTRATOR, where the characteristics of those ACCESSORIES can affect the BASIC SAFETY or ESSENTIAL PERFORMANCE of the OXYGEN CONCENTRATOR. This particular standard does not specify the requirements for OXYGEN CONCENTRATORS for use with a MEDICAL GAS PIPELINE SYSTEM which are given in ISO 10083. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of the general standard. NOTE 2 See also 4.2 of the General Standard. This International Standard is a particular standard in the IEC 60601‐1 series of standards.
