ISO 16958:2015 specifies a method for the quantification of individual and/or all fatty acids in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)].
The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat ≥ 1,5 % m/m.
The fat extracted from products containing less than 1,5 % m/m fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, like soft or hard cheeses with acidity level ≤ 1 mmol/100 g of fat, can be analysed after a preliminary fat extraction using methods referenced in Clause 2. For products supplemented or enriched with PUFA with fish oil or algae origins, the evaporation of solvents should be performed at the lowest possible temperature (e.g. max. 40 °C) to recover these sensitive fatty acids.

This document specifies requirements for a valuation of energy related investments (VALERI). It provides a description on how to gather, calculate, evaluate and document information in order to create solid business cases based on Net Present Value calculations for ERIs. The standard is applicable for the valuation of any kind of energy related investment.
The document focusses mainly on the valuation and documentation of the economical impacts of ERIs. However, non-economical effects (e.g. noise reduction) that may occur through undertaking an investment are considered as well. Thus, qualitative effects (e.g. impact on the environment)– even if they are non-monetisable – are taken into consideration.

This European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature.
This standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used.
This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water floor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings.
The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definitions in EN 1264 1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results.
The prove results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.

8. Scope
This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled.
This document deals with the use in practical engineering of the results coming from part 2 and 5 and is applicable to floor-, ceiling- and wall heating systems, as well floor-, ceiling- and wall cooling systems.
For heating systems, physiological limitations are taken into account when specifying the surface temperatures. In the case of floor heating systems the limitations are realised by a design based on the characteristic curves and limit curves determined in accordance with part 2 of this Standard.
For cooling systems, only a limitation with respect to the dew point is taken into account. In predominating practice, this means that physiological limitations are included as well.

This European Standard applies to water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. Part 5 of this standard deals with the recalculation of values determined in Part 2 of this European Standard for the system in question, using it for floor heating applications. The recalculation method described in this part of the standard enables the conversion of the calculation and test results of Part 2 into results for other surface orientations in the room, i. e. for ceiling and wall heating, as well as for the application as cooling surfaces, i. e. for floor, ceiling and wall cooling. It has to be emphasised that the test results of Part 2 of this European Standard are the basis of all calculation. Therefore the use of this prove method is necessary whether or not the system in question is used for heating or cooling application.
This European Standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used.

This document applies to the basic safety and essential performance of a high-frequency ventilator (HFV) in combination with its accessories, hereafter referred to as ME equipment:

intended for use in an environment that provides specialized care for patients whose conditions can be life-threatening and who can require comprehensive care and constant monitoring in a professional healthcare facility;

NOTE 1    For the purposes of this document, such an environment is referred to as a critical care environment. High-frequency ventilators for this environment are considered life-sustaining.

NOTE 2    For the purposes of this document, such a high-frequency ventilator can provide transport within a professional healthcare facility (i.e. be a transit-operable ventilator).

NOTE 3    A high-frequency ventilator intended for use in transport within a professional healthcare facility is not considered as an ventilator intended for the emergency medical services environment.

intended to be operated by a healthcare professional operator;

intended for those patients who need differing levels of support from artificial ventilation including ventilator-dependent patients; and

capable of providing more than 150 inflations/min.

There are three principal designations of HFV:

high frequency percussive ventilation (HFPV, with a typical HFV frequency of (60 to 1 000) HFV inflations/min); 

high frequency jet ventilation (HFJV, with a typical HFV frequency of (100 to 1 500) HFV inflations/min); and

high frequency oscillatory ventilation (HFOV, with a typical HFV frequency of (180 to 1200) HFV inflations/min and typically having an active expiratory phase). 

Additionally, HFV designations can be combined together or with ventilation at rates less than 150 inflations/min.

* A high-frequency ventilator is not considered to utilize physiologic closed loop-control system unless it uses a physiological patient variable to adjust the ventilation therapy settings.

This document is also applicable to those accessories intended by their manufacturer to be connected to an HFV breathing system, or to a high-frequency ventilator, where the characteristics of those accessories can affect the basic safety or essential performance of the high-frequency ventilator.

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 document are not covered by specific requirements in this document except in 7.2.13 and 8.4.1 of IEC 60601-1:2005.
