Laboratory furniture - Recommendations for design and installation - Part 5: Services distribution carriers

This document is applicable to biology, chemistry and physics laboratories where research, preparative, analytical, process activities take place and which can involve work with hazardous substances, including higher education (college and university teaching and post-graduate research). This document does not cover the requirements of schools, i.e. precollege/pre-university (refer to EN 13150), or highly specialist laboratories which need very specific, bespoke solutions to enable them to function. This document specifies requirements for various types of services distribution carriers typically used in combination with laboratory bench types as covered in the EN 14056 series. This document gives guidelines for all parties involved in the planning, design, manufacture, installation, testing of a new laboratory or in the refurbishment of an existing laboratory.

Heating systems in buildings - Design of heat pump heating systems

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. Design criteria for reversible heat pump systems for heating and cooling are also included in this document. Table 1 - Heat pump systems used for heating (within the scope)

Sterilization of health care products - Moist heat - Requirements for sterilizers used for the terminal sterilization of aqueous liquid in sealed containers (ISO/DIS 19253:2026)

Specifies the requirements and the relevant tests for sterilizers intended to be used for the terminal sterilization of health care products (medical devices or medicinal products) presented as aqueous liquid in sealed containers. The container can be rigid, semi rigid or flexible. The sterilizing agent, moist heat, is created internally from the product, heating being achieved by use of saturated steam, mixtures of steam and a pressure ballasting non-condensing gas such as air or super-heated water in the sterilizer chamber. The sterilizers can be used in both a health care and industrial setting. This standard does not apply to sterilizers using saturated steam for the sterilization of the surfaces of medical devices or sterilizers used in laboratories. NOTE 1 Sterilizers using saturated steam for sterilizing the surfaces of medical devices are covered by EN 285 and EN 13060. Laboratory sterilizers are covered by some national standards. NOTE 2 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of other aqueous liquid in sealed containers such as veterinary products or some foodstuffs. Note 3 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of a contained product enclosed within a sterile barrier system conforming to the EN ISO 11607 series of standards.

Ultrasonic domestic gas meters

This document specifies requirements and tests for the construction, performance and safety of class 1,0 and class 1,5 battery powered ultrasonic gas meters (hereinafter referred to as meters), having co-axial single pipe, or two pipe connections, used to measure volumes of distributed fuel gases of the 2nd and/or 3rd family gases as given in EN 437:2021, at maximum working pressures not exceeding 0,5 bar )) and maximum actual flow rates of up to 40 m3/h over a minimum ambient temperature range of −10 °C to +40 °C, and minimum gas temperature span of 40 K. This document applies to meters where the measuring element and the register(s) are enclosed in the same case. This document applies to meters with and without built-in temperature conversion, that are installed in locations with vibration and shocks of low significance and in - closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity; or, if specified by the manufacturer; - open locations (outdoor without any covering) both with condensing humidity or with non-condensing humidity; and in locations with electromagnetic disturbances likely to be found in residential, commercial and light industrial use. Unless otherwise stated, all pressures given in this document are gauge pressures. Clauses 1 to 14 are for design and type testing only. Requirements for electronic indexes, batteries, valves incorporated in the meter and other additional functionalities are given in EN 16314:2013 Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer. When more than one meter type is submitted for testing, then each meter type needs to be tested against this document.

Safety rules for the construction and installation of lifts - Examination and tests - Part 58: Landing doors fire resistance test

This document defines the fire resistance test and requirements for landing doors which are intended to provide a barrier to the spread of fire from the landing side and via the lift well in buildings for a period of time classified in this document. The fire resistance requirements are expressed in terms of integrity (E), insulation (EI) and radiation (EW). It is applicable to landing doors installed in the lift well openings at landings and used as means of access to lift car. It also specifies the method of testing and classification of fire resistance of landing doors. The test method is only valid for furnaces where the door is mounted in a vertical position. The test method specifies the measurement of integrity and if required the measurement of radiation and thermal insulation. This document refers to CO2 as means of tracing the propagation of fire. The document does not cover hazards due to emission of gases. This document is not applicable to landing doors which are installed before the date of its publication.

Installation and operation of electrical test stations

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.
