ČSN EN 707 Tento dokument, když je používán společně s EN ISO 4254-1, stanovuje bezpečnostní požadavky a jejich ověřování pro návrh a konstrukci návěsných, přívěsných a samojízdných kejdovačů, včetně jejich rozstřikovacích nebo zapravovacích zařízení, určených pro manipulaci a přepravu a/nebo zapracování kejdy, které jsou poháněny buď pneumaticky, nebo mechanicky. Kromě toho specifikuje typy informací o bezpečných způsobech práce, které mají být poskytnuty výrobcem. Pokud jsou požadavky tohoto dokumentu rozdílné od těch, které stanovuje EN ISO 4254-1, pak mají požadavky tohoto dokumentu přednost před požadavky EN ISO 4254-1 pro stroje, které byly navrženy a vyrobeny podle ustanovení tohoto dokumentu. Tento dokument společně s EN ISO 4254-1 řeší všechna významná nebezpečí, nebezpečné situace a události vztahující se ke kejdovačům, když jsou používány tak, jak je předpokládáno a za podmínek nesprávného použití důvodně předpokládaném výrobcem (viz tabulka A.1), s výjimkou nebezpečí vztahujících se k bezpečnosti na silnici (např. řízení, brzdění). Environmentální aspekty nejsou v tomto dokumentu řešeny. Tento dokument neplatí pro kejdovače, které byly vyrobeny před datem tohoto vydání EN.

ČSN P CEN/TS 17329-2 This document provides information on how the performance characteristics of qualitative (binary) real-time polymerase chain reaction (PCR) methods for detection of specific DNA sequences present in foods should be evaluated and validated by conducting a collaborative study. The guidelines are applicable for validation of qualitative PCR methods used for detection of DNA sequences derived from genetically modified foodstuffs. They can be applicable also for PCR methods used for detection of other target sequences in foodstuffs, e.g. for species detection and identification.

Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize ASA, AEPDS and ACS moulding and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 19065-1. In order to obtain reproducible and comparable test results, it is intended to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

ČSN EN ISO 22700 This document specifies a method for the correct measurement of the colour of finished leather by instrumental means. The document describes general concepts of colour measurement adapted to leather and the calculation of differences in colour. This document defines the following: a) the use of D65 as the standard light source for the leather industry; b) the use of D65 light source 10° as standard conditions for colour matching, for the definition of daylight simulators and as the reference light source for metamerism analysis; c) the use of CIEDE2000 as the colour difference formula.

ČSN EN 17199-3 This document provides the methodology for measuring the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions and specifies for that purpose the continuous drop method. This document specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data. The methodology described in this document enables a) the measurement of the respirable and, optionally, the inhalable dustiness mass fractions, b) the measurement of the number-based dustiness index of particles in the particle size range from about 10 nm to about 1 µm, c) the measurement of the number-based emission rate of particles in the particle size range from about 10 nm to about 1 µm, d) the measurement of the number-based particle size distribution of the released aerosol in the particle size range from about 10 nm to about 10 µm, and e) the collection of released airborne particles in the respirable dustiness mass fraction for subsequent observations and analysis by analytical electron microscopy. This document is applicable to the testing of a wide range of bulk materials including powders, granules or pellets containing or releasing respirable NOAA or other respirable particles in either unbound, bound uncoated and coated forms. NOTE 1: Currently no number-based classification scheme in terms of dustiness indices or emission rates have been established. Eventually, when a large number of measurement data has been obtained, the intention is to revise this document and to introduce such a classification scheme, if applicable. NOTE 2: The methods specified in this document have not been evaluated for nanofibers and nanoplates.

ČSN EN 17199-2 This document provides the methodology for measuring the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions and specifies for that purpose the rotating drum method. This document specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data. The methodology described in this document enables a) the measurement of the respirable, thoracic and inhalable dustiness mass fractions, b) the measurement of the number-based dustiness index of respirable particles in the particle size range from about 10 nm to about 1 µm, c) the measurement of the number-based emission rate of respirable particles in the particle size range from about 10 nm to about 1 µm, d) the measurement of the number-based particle size distribution of the released aerosol in the particle size range from about 10 nm to about 10 µm, and e) the collection of released airborne particles in the respirable fraction for subsequent observations and analysis by analytical electron microscopy. NOTE 1: The particle size range described above is based on the equipment used during the pre-normative research [4]. This document is applicable to the testing of a wide range of bulk materials including powders, granules or pellets containing or releasing respirable NOAA or other respirable particles in either unbound, bound uncoated and coated forms. NOTE 2: Currently no number-based classification scheme in terms of dustiness indices or emission rates have been established. Eventually, when a large number of measurement data has been obtained, the intention is to revise this document and to introduce such a classification scheme, if applicable. NOTE 3: The method specified in this document has not been investigated for the measurement of the dustiness of bulk materials containing nanofibres and nanoplates in terms of number-based dustiness indices or emission rates. However, there is no reason to believe that the number-based dustiness indices or emission rates could not be measured with the rotating drum method using the set-up described in this document.
