This document specifies a test method and the minimum requirements for fungicidal or yeasticidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water, or – in the case of ready-to-use products – with water. Products can only be tested at a concentration of 80 % or less (97 % with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substance.

This document applies to products that are used in the medical area in the fields of hygienic handrub, hygienic handwash, surgical handrub, surgical handwash, instrument disinfection by immersion, and surface disinfection by wiping, spraying, flooding or other means.

This document applies to areas and situations where disinfection or antisepsis is medically indicated. Such indications occur in patient care, for example:

—    in hospitals, in community medical facilities and in dental institutions;

—    in clinics of schools, of kindergartens and of nursing homes;

and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patients.

NOTE 1       The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.

NOTE 2       This method corresponds to a phase 2 step 1 test.

EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”.

This document specifies a test method simulating practical conditions for establishing whether a product for hygienic handrub reduces the release of virus contamination on hands when rubbed onto the artificially contaminated hands of volunteers.

NOTE 1        Attention is drawn to the fact that tests on human volunteers are the subject of legal provisions in certain European countries/regions.

This document applies to products for hygienic handrub for use in areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example:

–      in hospitals, in community medical facilities and in dental institutions;

–      in clinics of schools, of kindergardens and of nursing homes;

and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patient.

EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”.

NOTE 2       This method corresponds to a phase 2, step 2 test.

Replacement:

This document is applicable to the basic safety and essential performance of an anaesthetic workstation for administering inhalational anaesthesia whilst continuously attended by a professional operator.

This document specifies particular requirements for a complete anaesthetic workstation and the following anaesthetic workstation components which, although considered as individual devices in their own right, may be utilized, in conjunction with other relevant anaesthetic workstation components, to form an anaesthetic workstation to a given specification:

anaesthetic gas delivery system;

anaesthetic breathing system;

anaesthetic gas scavenging system;

anaesthetic vapour delivery system;

anaesthetic ventilator;

monitoring equipment;

alarm system;

protection device.

NOTE 1       Monitoring equipment, alarm systems and protection devices are summarized in Table AA.1.

An anaesthetic workstation supplied complete and its individual components are considered as ME equipment or ME systems with regard to the general standard.

NOTE 2       The applicability of this document is indicated in Table AA.2.

This document is also applicable to those accessories intended by their manufacturer to be connected to an anaesthetic workstation where the characteristics of those accessories can affect the basic safety and essential performance of the anaesthetic workstation.

If a clause or subclause is specifically intended to be applicable to anaesthetic workstation components or its accessories 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 an anaesthetic workstation and its individual components including accessories, as relevant.

Hazards inherent in the intended physiological function of an anaesthetic workstation and its individual components including accessories within the scope of this document are not covered by specific requirements in this document except in 7.2.13 and 8.4.1 of the general standard.

NOTE 3       See also 4.2 of the general standard.

This document is not applicable to any anaesthetic workstation intended for use with flammable anaesthetic agents, as determined by Annex BB.

The present document specifies a method for direct extraction of DNA from soil samples to analyse the abundance and composition of microbial communities by various techniques of molecular biology including real-time quantitative PCR (qPCR). This method is mainly dedicated to agricultural and forest soils. This method can possibly not be suitable for soils rich in organic matter (e.g. peat soils) or soils heavily polluted with organic pollutants or heavy metals.

The direct extraction of DNA from soil samples provides unique insight into the α- and β-diversity of microbial communities. Next-generation sequencing of amplicons obtained by PCR (polymerase chain reaction) amplification of soil DNA constitutes a promising domain which will in the near future contribute to the development of routine tools to monitor microbial communities in soil environments.

This document specifies three methods for the digestion of soil, treated biowaste, sludge and waste by the use of an acid mixture composed of hydrochloric (HCl), nitric (HNO3) and tetrafluoroboric (HBF4) or hydrochloric (HCl), nitric (HNO3) and hydrofluoric (HF) acid as the digestion solution.

Digestion with these acids is effectively considered as a total decomposition of the sample. For a broad range of samples the extracted analyte concentrations will reflect the total content in the sample.

This document is applicable for the following elements:

Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K), selenium (Se), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), thallium (Tl), tin (Sn), titanium (Ti), vanadium (V), and zinc (Zn).

This document can also be applied for the digestion of other elements, provided the user has verified the applicability.
