ČSN EN 14135 Tato norma se vztahuje na všechny typy obkladů, zahrnující, ale nejen, omítky a desky s nebo bez vzduchových mezer a instalované s různými podpěrnými systémy. Tato norma specifikuje metodu pro stanovení schopnosti obkladu chránit podkladové materiály před poškozením během stanovené doby vystavení požáru. Tato norma není určena pro hodnocení klasifikace požární odolnosti (např. EI, EW, E) nebo klasifikace reakce na oheň (specifikováno v EN 13501-1). Schopnost ochrany proti požáru je ovlivněna přítomností hořlavých materiálů v dutině za obkladem. Použitelnost výsledků je omezena množstvím a umístěním těchto hořlavých materiálů v dané dutině. POZNÁMKA - Povolené množství hořlavých materiálů v dutině je obecně stanoveno národními předpisy.

ČSN EN ISO 14019-4 This document specifies principles and requirements for the competence, consistent operation and impartiality of bodies performing validation/verification of declared sustainability information. This document is an application of ISO/IEC 17029, which contains general principles and requirements for the competence, consistent operation and impartiality of bodies performing validation/verification as conformity assessment activities. This document includes specific requirements related to bodies performing validation/verification of declared sustainability information in addition to the requirements of ISO/IEC 17029. Any programme requirements related to bodies are additional to the requirements of this document.

ČSN EN 13807 This document specifies the requirements for the design, manufacture, identification and testing of battery vehicles and multiple-element gas containers (MEGCs) containing cylinders, tubes, or bundles of cylinders. This document applies also to battery vehicles and MEGCs containing bundles of cylinders connected by a manifold which are dis-assembled from the battery vehicle and filled individually. It is applicable to battery vehicles and MEGCs containing compressed gas, liquefied gas, and mixtures thereof. It is also applicable to battery vehicles for dissolved acetylene. This document is not applicable to battery vehicles and MEGC for toxic gases with an LC50 value less than or equal to 200 ml/m3. This document does not apply to battery vehicles and MEGCs containing pressure drums or tanks. This document does not specify requirements for the vehicle chassis or motive unit. This document is primarily intended for industrial gases other than liquefied petroleum gases (LPG).

ČSN EN ISO 14644-14 This document specifies a methodology to assess the suitability of equipment (e.g. machinery, measuring equipment, process equipment, components and tools) for use in cleanrooms and associated controlled environments, with respect to airborne particle cleanliness as specified in ISO 14644-1. Particle sizes range from 0,1 µm to equal to or larger than 5 µm (given in ISO 14644-1).

ČSN EN ISO 5210 This document specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this document, "actuator" can be understood as "actuator" or "combination of actuator with gearbox" providing a multi-turn or linear output. This document specifies: - flange dimensions necessary for the attachment of actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)]; - those driving component dimensions of actuators which are necessary to attach them to the driven components; - reference values for torque and thrust for flanges having the dimensions specified in this document.

ČSN EN 50483-6 ed. 2 The EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This document defines the environmental tests in particular the climatic and corrosion ageing tests. The objective of these tests is to predict the behaviour of ABC accessories when subjected to sun radiation, to weather conditions (humidity, spraying water, heat, cold) and pollution. EN 50483-1, EN 50483-2, EN 50483-3 and EN 50483-4 specify which type tests included in this part of the standard are needed.

ČSN EN 50483-2 ed. 2 The EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This document applies to tensioning devices consisting of tension and suspension clamps, fittings and brackets designed to be used for installation of self-supporting ABC defined in HD 626 S2. Tests described in this document are type tests.

ČSN EN 50483-5 ed. 2 The EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This document applies to the connections described in EN 50483-4, including branch connectors, Insulation Piercing Connectors (IPC), pre-insulated lugs (terminals) and through pre-insulated connectors (sleeves). Two classes of connectors are covered by this document: - Class A: These are connectors intended for electricity distribution or industrial networks in which they can be subjected to short-circuits of relatively high intensity and duration. As a consequence, Class A connectors will be suitable for the majority of applications. -Class B: These are connectors for networks in which overloads or short-circuits are rapidly cleared by the operation of protection devices. Depending on their application, the connectors are subjected to heat cycles and short-circuit current tests. Class A: the connectors are subjected to heat cycles and short-circuit current tests. Class B: the connectors are subjected to heat cycles only. The object of this document is to define the heating cycles test methods and requirements which apply to compression through connectors, insulation piercing connectors and all other type of connections for low voltage aerial bundled cables.
