language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 13795-2:2023) 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 will supersede EN 13795-2:2019.
prEN 13795-2:2023 includes the following significant technical changes with respect to
EN 13795-2:2019:
a) Clarification of testing specifications and reporting of results;
b) Expansion of Annex C (formerly read “Environmental aspects”) to include considerations regarding
environmental impact and circular economy (now Annex C “Environmental impact”);
c) Alignment to Regulation (EU) 2017/745 (including updated Annex ZA);
d) Update of normative references and bibliography.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
EN 13795 consists of the following parts, under the general title Surgical clothing and drapes —
Requirements and test methods:
— Part 1: Surgical drapes and gowns
— Part 2: Clean air suits
prEN 13795-2:2023 (E)
Introduction
Clean air suits are used to minimize the spread of infective agents to patients’ surgical sites and
equipment, through prevention of dispersal of bacteria-carrying skin scales from the operating room
staff, thereby helping to prevent post-operative surgical site infections.
The performance required of working clothes for clinical staff varies with, for example, the type and
duration of the procedure, and the susceptibility of the patient to infection. In infection-prone invasive
operations, a clean air suit can contribute to reduction of infection risks, in conjunction with ventilation
and correct working methods.
This document is intended to assist the communication between manufacturers and third parties with
regard to material or product characteristics and performance requirements.
Therefore, Annex B provides comprehensive information on characteristics, measurement of
performance and performance requirements. Annex C clarifies that this document does not include
environmental provisions. Annex D explains the concept of performance levels and provides guidance to
users for selecting products. Annex E gives information on the impact of the design of clean air suits and
the source strength concept as an evaluation means for the impact of the entire clothing (including clean
air suits) on particle release.
This document focuses on General Safety and Performance Requirements (GSPR) arising from the
Medical Device Regulation (EU) 2017/745, which are applicable to clean air suits. The requirements and
guidance in this document are expected to be of help to manufacturers and users when designing,
processing, assessing and selecting products. It is the intention of this document to ensure the same level
of safety from single-use and reusable clean air suits throughout their useful life.
prEN 13795-2:2023 (E)
1 Scope
This document specifies information to be supplied to users and third-party verifiers in addition to the
usual labelling of medical devices (see EN ISO 20417 and EN ISO 15223-1), concerning manufacturing
and processing requirements.
This document gives information on the characteristics of single-use and reusable clean air suits used as
medical devices for clinical staff, intended to prevent the transmission of infective agents between clinical
staff and patients during surgical and other invasive procedures.
This document specifies test methods for evaluating the identified characteristics of clean air suits and
sets performance requirements for these products.

3.1
colony forming unit
CFU
unit by which the culturable number of microorganisms is expressed
Note 1 to entry: The culturable number is the number of microorganisms, single cells or aggregates, able to form
colonies on a solid nutrient medium.

clean air suit
suit, used as working garment, intended and shown to minimize contamination of the operating room air

requirements for a clean air suit. The scrub suit is not primarily intended to prevent airborne dispersal from staff
and can be designed and processed as the manufacturer thinks fit.

barrier hood.

manufacturer
natural or legal person with responsibility for the design, manufacture, packaging and labelling of a device
