ČSN EN 13284-1 This European Standard specifies the standard reference method (SRM) for the measurement of low dust concentration in ducted gaseous streams in the concentrations below 50 mg/m3 at standard conditions. This European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators. More generally, it can be applied to gases emitted from other stationary sources, and to higher concentrations. If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the sampling and filter treatment conditions. This method has been validated in field tests with special emphasis to dust concentrations around 5 mg/m3. The results of the field tests are presented in Annex A.

ČSN ETSI EN 301 925 V1.5.1 The present document specifies the minimum requirements for shipborne radio transmitters and receivers for fixed installations operating in the VHF frequency bands between 156 MHz and 174 MHz used by the maritime mobile service, using both 25 kHz and 12,5 kHz channels and capable of Radiotelephony and Digital Selective Calling communications within the Global Maritime Distress and Safety System. The present document incorporates the requirements of the relevant resolutions of the International Maritime Organization (IMO) and is primarily intended to specify equipment suitable for fitting to ships subject to the SOLAS Convention [i.2] and complying with the Council Directive 2014/90/EU [i.3] of 23 July 2014 on marine equipment (the European Marine Equipment Directive). The present document does not address the testing of ancillary equipment on a stand-alone basis, i.e. separately from the radio equipment with which it is to be used.

ČSN EN ISO 22477-4 (72 1008) This document establishes the specifications for the execution of dynamic load tests in which a single pile is subject to an axial dynamic load in compression. This document outlines the methods of testing required to allow assessment of pile resistance to be determined from the following methods and procedures described in EN1997 -1: 2004+A1: 2013: a) dynamic impact testing - determination of pile compressive resistance by evaluation of measurements of strain and acceleration and or displacement at the pile head with respect to time; b) pile driving formulae - evaluation of pile compressive resistance from blow counts and hammer energy during pile driving; c) wave equation analysis - evaluation of pile compressive resistance from blow counts by modelling of the pile, soil and driving equipment; d) multi-blow dynamic testing - evaluation of pile compressive resistance from a series of blows designed to generate different levels of pile head displacement and velocity. This document is applicable to piles loaded axially in compression. This document is applicable to all pile types mentioned in EN 1536, EN 12699 and EN 14199. The tests considered in this document are limited to dynamic load tests on piles only. NOTE 1 - ISO 22477-4 can be used in conjunction with EN1997 -1: 2004+A1: 2013. Numerical values of partial factors for limit states from pile load tests to be taken into account in design are provided in EN 1997-1. For design to EN 1997-1 the results from dynamic load tests will be considered equivalent to the measured compressive resistance Rc,m after being subject to appropriate analysis. NOTE 2 - Guidance on analysis procedures for dynamic load testing results is given in Annexes A, B, D, E and F. This document provides specifications for: i) investigation tests, whereby a sacrificial pile is loaded up to ultimate limit state; ii) control tests, whereby the pile is loaded up to a specified load in excess of the serviceability limit state. NOTE 3 - Generally, an investigation test focuses on general knowledge of a pile type; a control test focuses on one specific application of a pile.
