ČSN EN 17109+A1 This document specifies safety requirements and test methods for components of an individual safety system for protection against a fall from height used in permanent and mobile rope courses as defined in EN 15567 1:2015+A1:2020". The products considered in this document" are not intended to limit, by themselves, the deceleration of the fall of the user, as defined in EN 15567 1:2015+A1:2020". For this requirement, it is essential to consider the whole ropes course system. Safety lines and harnesses are not covered in this document".

ČSN EN ISO 26101-2 Tento dokument stanovuje metody určování způsobilosti akustického prostředí, které se blíží volnému zvukovému poli v blízkosti jedné nebo více odrazivých rovin. Cílem určování způsobilosti je stanovit korekci na prostředí K2, která se používá ke korekci na odražený zvuk při určování hladiny akustického výkonu nebo hladiny akustické energie zdroje hluku z hladin akustického tlaku měřených na ploše obklopující zdroj hluku (stroj nebo zařízení) v daném prostředí. V praxi bude stanovená hodnota K2 funkcí jak odraženého zvuku od zkušebního prostředí, tak tvaru a velikosti měřicí plochy použité pro určení K2. Pro účely tohoto dokumentu a dokumentů, které na něj odkazují, se předpokládá, že rozdíly mezi hodnotami K2 určenými pomocí různých měřicích ploch jsou pro danou zkušební metodu zahrnuty v uvedené nejistotě měření.

ČSN EN 17249-5 In respect of operating requirements specified in EN 16072, this document specifies adaptations to enable the provision of eCall for powered two-wheel vehicles. As with the existing provisions for eCall for category M1/N1 vehicles, these are specified within the paradigm of being OEM-fit equipment supplied with new vehicles. This document includes only the requirements for category L1 and L3 P2WV (vehicle based) with the exception of L1e-A (powered cycle), although other documents can subject other 'L' subcategories to use this document. Other documents can be prepared for other UNECE category 'L' variants. The requirements herein relate only to the provision of pan-European eCall and does not provide requirements for third party service provision of eCall. Other than in the 112-eCall using IMS over packet switched networks paradigm, which involves a direct call from the vehicle to the most appropriate PSAP, third party service provision involves the support of an intermediary third-party service provider before the call is forwarded to the PSAP. The provision of eCall for vehicles via the aftermarket (post sales and registration), and the operational requirements for any such aftermarket solution, will be the subject of other work.

ČSN EN ISO 16784-1 This document specifies general requirements and parameters for the pilot test evaluation of corrosion and scaling control additives in open recirculating cooling water systems. This document covers parameters including test unit design, operation, water quality and contamination. It also covers the design and operation of pilot test devices as well as parameters to be evaluated in pilot test units. This document covers the criteria that are used in pilot scale testing programmes for selecting water treatment programmes for specific recirculating cooling water systems. This document is only applicable to open recirculating cooling water systems. It does not apply to closed cooling systems and once-through cooling water systems. This document applies only to systems that incorporate shell and tube heat exchangers with standard uncoated smooth tubes and cooling water on the tube side. This document does not apply to heat exchangers with shell-side water, plate and frame and/or spiral heat exchangers and other heat exchange devices. However, when the test conditions are properly set up to model the surface temperature and shear stress in more complex heat transfer devices, the test results can predict the results of operating heat exchangers of that design. The test criteria established in this document are not intended to govern the type of bench and pilot scale testing normally carried out by water treatment companies as part of their proprietary product development programmes. However, water treatment companies can choose to use the criteria in this document as guidelines in the development of their own product development test procedures.

ČSN EN 12814-8 This document provides the requirements for the tests made on welded thermoplastics semi-finished products. The selection of the appropriate test method(s) is made in accordance with the particular type and application of welded product. The test results depend on the conditions of manufacture for the test specimen and on the test conditions. They can therefore only be related to the behaviour of the product or can only be used for designing a structure, if the test conditions can be related to the service conditions

ČSN EN ISO 5640 This document provides requirements for metallic mounting kits for part-turn valves and actuator attachments. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up to F30 flange type). It applies to mounting kits for part-turn valves and actuators with integral attachment flanges and drive components as described in ISO 5211 (see Figure 1), when direct mounting of the actuator on valve is not practical. Figure 1 illustrates the two different types of mounting kits in the scope of this document. a) Direct interface with mounting kit b) Direct interface with mounting kit (when combination of a multi-turn actuator and a gearbox) Stacking of mounting kits/intermediate supports is not within the scope of this document. This document specifies methods for design and environmental corrosion protection. When a reference is made to this document, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, prior to order. In this document, the term "valve" covers valve or shaft extension top-flange, and the term "actuator" covers part-turn actuator or combination of multi-turn actuator and gearbox. Control valves are excluded from this document.

ČSN EN 12522 This document specifies the requirements for a furniture removal service and its provision and the general terms and conditions of contract subject always to any applicable national legislation, licensing or contractual constraints. This document applies only to furniture removal services for private individuals where the contract is entered into by an individual or by an employer or relocation agent when the latter requires the moving of personal property, generally consisting of non-commercial property and/or property which is in current use.
