The work of preparing International Standards is normally carried out thro
14、ugh ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabor
15、ates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval c
16、riteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject
17、 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

20、Certain surgical, diagnostic, and therapeutic techniques can generate noxious airborne contaminants (plume) as by-products, particularly from procedures that include the cutting, ablation, cauterization, or mechanical manipulation of target tissue by energy-based devices such as lasers, electrosurgi
21、cal generators, broadband light sources, ultrasonic instruments, etc. or mechanical surgical tools such as bone saws, high speed drills, and reamers. New technologies in cutting and sealing can result in less plume generation (see Reference85) but plume remains a hazard. Energy-based contact with ar
22、ticles such as tubing, swabs, and skin preparation solutions will produce additional chemicals. This International Standard was developed in response to awareness of the potential hazards to patients and staff of plume generated by these techniques in healthcare settings.Plume can contain a variety
23、of contaminants: viable bacteria (including multi-resistant strains), viruses, cellular debris (including DNA), airborne chemicals, particulates, ultrafine particles, aerosols, gases, vapours, and fumes (including fumes from metals). In vitro studies of bacterial and viral contamination have found v
24、iable Escherichia coli, Staphylococcus aureus, human papillomavirus (HPV), hepatitis viruses (HVB, HVC), and human immunodeficiency virus (HIV) in plume. The gases in plume can include toxic substances such as benzene, formaldehyde, and hydrogen cyanide. Plume can also contain aerosolized blood (pla
25、sma, cells, or fragments of cells) and blood-borne pathogens.Plume thus poses a hazard to exposed persons. It can transmit infection, or have mutagenic or carcinogenic effects. Plume can also cause irritation of the mucous membranes, eyes, respiratory system, and skin. Additionally, plume reduces th
26、e clinicians ability to clearly see the operative field, resulting in unsafe operating conditions.This International Standard specifies requirements for systems for evacuation of plume generated in healthcare facilities. It is intended for those persons involved in the design, construction, inspecti
27、on, and operation of healthcare facilities. Those persons involved in the design, manufacture, installation, testing, and use of equipment and components for plume evacuation systems should also be aware of the contents of this International Standard.This International Standard seeks to ensure that
28、plume generated in healthcare facilities is not evacuated through the medical vacuum or anaesthetic gas scavenging systems. For this reason, type-specific components are specified for terminal units and for other connectors which are intended to be used by the operator.The objectives of this Interna
29、tional Standard are to ensure the following:a) non-interchangeability with other products or pipeline systems by design;b) continuous extraction at specified pressures and flows;c) use of suitable materials for all components of the system;d) provision of monitoring indicators and alarm systems;e) c
30、orrect rating of filtration systems;f) correct indication of filter life;g) correct marking and labelling;h) electrical and environmental testing;i) correct installation;j) testing, commissioning, and certification;k) provision of guidance on operational management;l) appropriate manufacturers instr
31、uctions for use, training, service, and maintenance.vi ISO 2014 All rights reservedBS ISO 16571:2014ISO 16571:2014(E)Annex F contains rationale statements for some of the requirements of this International Standard. It is included to provide additional insight into the reasoning that led to the requ
32、irements and recommendations that have been incorporated into this International Standard. The clauses and subclauses marked with * after their number have corresponding rationale contained in Annex F. It is considered that knowledge of the reasons for the requirements will not only facilitate the p
33、roper application of this International Standard, but will expedite any subsequent revisions.

34、 the design, manufacture, installation, function, performance, maintenance, servicing, documentation, testing, and commissioning of equipment for evacuation of plume generated by medical devices.NOTE A plume evacuation system (PES) can be a functionally independent component of a medical device that
35、 has other functions.1.2 This International Standard is applicable toa) portable and mobile plume evacuation systems,b) local stationary plume evacuation systems,c) dedicated central pipeline systems for plume evacuation systems, andd) plume evacuation systems integrated into other equipment (e.g. l
36、aser equipment).1.3* This International Standard does not apply to active and passive devices used to evacuate plume generated during invasive (e.g. laparoscopic or endoscopic) procedures.1.4 This International Standard does not apply to the following:a) anaesthetic gas scavenging systems (AGSSs) wh
37、ich are covered in ISO 7396-2;b) medical vacuum systems which are covered in ISO 7396-1;c) heating, ventilation, and air-conditioning (HVAC) systems;d) aspects of laser safety other than airborne contamination;NOTE Some other aspects of laser safety are covered by IEC 60825 (see Reference7).e) aspec
38、ts of electrosurgery, electrocautery, and mechanical surgical tools other than airborne contamination produced by such equipment resulting from interaction with tissue or materials.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are
