1.1 This document is applicable to the installation and operation of fixed and temporary electrical test installations. 1.2 Compliance with this document needs to be applied, if contact with live parts presents dangerous. This is the case when: a) the voltage exceeds 25 V AC (frequencies lower than 500 Hz) or 60 V DC and current exceeds 3 mA for AC or 12 mA for DC, or b) the voltage exceeds 25 V AC (for any frequency) or 60 V DC and the discharge energy of the test station and test object exceeds 350 mJ, or c) at frequencies above 500 Hz the national determined current and voltage values are applied. If there are no national requirements, determined reference values for permissible body currents and contact voltages can be taken from Table A.1; This document is applicable even if conditions a) to c) are fulfilled, due to other possible risks, e.g. risk of fire or explosion. NOTE The values for the resultant current of 3 mA AC or 12 mA DC comply with the information about the effects of current on human beings and livestock in IEC/TS 60479 1. 1.3 Some specifications in this document refer to a voltage value of 1 000 V. This value applies to AC voltages and is equated to a value of 1 500 V DC voltage. 1.4 Where no requirements are given in this document, the documents of the HD 60364 series (for nominal voltages up to 1 000 V) or EN IEC 61936 1 and EN 50522 (for nominal voltages exceeding 1 kV) apply to the installation of electrical test installations and EN 50110 1 applies to the operation of electrical test installations. 1.5 This document does not apply to the power supply to the test installations. In this case, the documents of the HD 60364 series (for nominal voltages up to 1 000 V) or EN IEC 61936 1 (for nominal voltages exceeding 1 kV) apply to their installation and EN 50110 1 applies to their operation.

This document specifies design criteria for heating and cooling systems in buildings using electrically driven heat pumps for heating and cooling alone or in combination with other heat generators. The heat pump systems considered in this document (source system/sink system) are listed in Table 1. For cooling purposes, energy source and energy sink can be reversed. This document also applies to other energy sources such as wastewater, massive absorbers, ice storage systems, as well as heat pump systems using more than one energy source. This document takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of the heat supply but does not cover the design of these systems. This document covers the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system, the control of the whole system and the aspects dealing with energy source of the system.

Trąšos, kalkinimo medžiagos ir inhibitoriai. Fosfonatų kiekio nustatymas jonų chromatografija su laidumo aptikimu (IC-CD)

This document specifies a method for the extraction and determination of phosphonates (P-PO3) in fertilizers, liming materials and inhibitors using ion chromatography and conductivity detection (IC-CD). This document is applicable to fertilizing product blends, where the blend is a mix of at least two of the following components, fertilizers, liming materials, soil improvers, growing media, inhibitors and plant biostimulants, and where the following category, fertilizers, liming materials and inhibitors, is the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If fertilizers, liming materials and inhibitors is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

This document specifies two different methods (Method A and B) for the determination of the content of potassium (expressed as K2O) in inorganic fertilizers. Method A specifies a gravimetric method. Method B specifies the method using inductively coupled plasma optical emission spectrometry (ICP-OES). This document is applicable to fertilizing product blends, where the blend is a mix of at least two of the following components, fertilizers, liming materials, soil improvers, growing media, inhibitors and plant biostimulants, and where inorganic fertilizers are the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If inorganic fertilizers are not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome.
