ČSN EN 334+A1 (38 6445) This document specifies constructional, functional, testing, marking, sizing and documentation requirements of gas pressure regulators: - for inlet pressures up to 100 bar and nominal diameters up to DN 400; - for an operating temperature range from - 20 °C to +60 °C, which operate with fuel gases of the 1st and 2nd family as defined in EN 437:2018 [1], used in the pressure control stations in accordance with EN 12186 or EN 12279, in transmission and distribution networks and also in commercial and industrial installations. "Gas pressure regulators" hereafter will be called "regulators" except in the titles. For standard regulators when used in pressure control stations complying with EN 12186 or EN 12279, the Annex ZA lists all applicable essential safety requirements of the European legislation on pressure equipment except external and internal corrosion resistance for applications in corrosive environment. This document considers the following temperature classes/types of regulators: - temperature class 1: operating temperature range from -10 °C to 60 °C; - temperature class 2: operating temperature range from -20 °C to 60 °C; - type IS: (integral strength type); - type DS: (differential strength type). This document applies to regulators which use the pipeline gas as a source of control energy unassisted by any external power source. The regulator may incorporate a second regulator, used as monitor, complying with the requirements in this document. The regulator may incorporate a safety shut off device (SSD) complying with the requirements of EN 14382. The regulator may incorporate a creep (venting) relief device, complying with the requirements in Annex E and/or a vent limiter, complying with the requirements in Annex I. This document does not apply to: - regulators upstream from/on/in domestic gas-consuming appliances which are installed downstream of domestic gas meters; - regulators designed to be incorporated into pressure control systems used in service lines ) with volumetric flow rate

ČSN ETS 300 172 ed. 2 This European Telecommunication Standard (ETS) defines the Layer 3 protocol for signalling for the support of circuit mode bearer services (used either on their own or in support of teleservices) at the Q reference point between Private Telecommunication Network Exchanges (PTNX) connected together within a Private Telecommunication Network (PTN). The Q reference point is defined in ENV 41004. Service specifications are produced in three stages and according to the method specified in ENV 41005. The definition of signalling protocols is stage 3 of the method. Stage 1 and stage 2 specifications of the basic circuit mode bearer services are to be found in ETS 300 171. The protocol defined in this ETS satisfies the requirements identified by the stage 1 and stage 2 specifications in ETS 300 171.

ČSN EN 13814-1+A1 This document specifies the minimum requirements necessary to ensure the safe design, calculation, manufacture, and installation of mobile, temporary or permanently installed machinery and structures which are intended for use by persons as a leisure activity, e.g. roundabouts, swings, boats, ferris wheels, roller coasters, chutes, booths, side shows, and structures for artistic aerial displays. The above items are hereafter called amusement devices, which are intended to be installed both repeatedly without degradation or loss of integrity, and temporarily or permanently in fairgrounds and amusement parks or any other locations. Grandstands, construction site installations, scaffolding, removable agricultural structures, simple coin operated children's amusement devices, carrying up to three children, and recreational devices like waterslides or summer toboggan runs, playground equipment, rope courses, climbing wall, inflatable, trampolines, swimming pool equipment (this list is not exhaustive) are not covered by this document. For all the equipment not covered by the requirements of EN 13814 1, the relevant standards apply. Nevertheless this document can be used in the design of any similar structural or passenger carrying amusement device not explicitly mentioned herein. In terms of workers' health and safety, national regulations apply. This document is applicable to manufacturing and major modification of amusement devices and rides for designs after the effective date of publication.

ČSN EN IEC 60335-2-40 ed. 4 This part of IEC 60335 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units. Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase appliances. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above can consist of one or more factory-made assemblies. If provided in more than one assembly, the separate assemblies are used together, and the requirements are based on the use of matched assemblies.

ČSN ETSI EN 301 908-13 V13.3.1 The present document applies to the following radio equipment type: User Equipment for Evolved Universal Terrestrial Radio Access (E-UTRA). This radio equipment type is capable of operating in all or any part of the frequency bands given in tables from 1-1 through 1-5. E-UTRA NB-IoT is designed to operate in the E-UTRA operating bands 1, 3, 8, 20, 28 and 65 defined in table 1-1. The present document covers requirements for E-UTRA FDD and E-UTRA TDD User Equipment from 3GPP™ Releases 8, 9, 10, 11, 12, and 13 defined in ETSI TS 136 101 [3]. This includes the requirements for E UTRA UE operating bands and E-UTRA CA operating bands from 3GPP™ Release 13 defined in ETSI TS 136 101 [3]. NOTE 2 - For Band 20: For user equipment designed to be mobile or nomadic, the requirements in the present document measured at the antenna port also show conformity to the corresponding requirement defined as Total Radiated Power (TRP), as described in Commission Decision 2010/267/EU [i.6] and ECC Decision (09)03 [i.7]. For user equipment designed to be fixed or installed, the present document does not address the requirements described in Commission Decision 2010/267/EU [i.6] and ECC Decision (09)03 [i.7]. The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
