ČSN EN 18054 This document specifies a method for instrumental analysis by elemental analyser-isotope ratio mass spectrometry (EA-IRMS) of food materials to determine C and/or N isotope ratios. The isotope ratios obtained by following this document are expressed as ?13C and/or ?15N values relative to international measurement standards. This document does not apply to sample preparation. It is assumed that the food sample has been pretreated as necessary and homogenized. Similarly, the interpretation of the obtained isotope delta values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials. Solid and/or liquid sample materials can be analysed following this document. Although other instrumental techniques can be applied to determine ?13C and/or ?15N values in food materials, these other techniques are not covered by this document.

ČSN EN ISO 9241-112 This document establishes ergonomic design principles for interactive systems related to the software-controlled presentation of information by user interfaces. It applies to the three main modalities (visual, auditory, tactile or haptic) typically used in information and communication technology (ICT). These principles apply to the perception and understanding of presented information. These principles are applicable in the analysis, design and evaluation of interactive systems. This document also provides recommendations corresponding to the principles. The recommendations for each of the principles are not exhaustive and are not necessarily independent from one another. While this document is applicable to all types of interactive systems, it does not cover the specifics of particular application domains which require context-specific recommendations. This document also applies to outputs from interactive systems (such as printed documents and document exports in common computer formats, e.g. pdf, text and tabular formats).
