Surface chemical analysis — Surface chemical analysis of bacteria and biofilms
Käsitlusala:
This document gives an overview of a variety of physical and analytical methods by which bacteria, biofilms, and the interaction of those with antimicrobial compounds can be analysed. For each technique a general overview is given and its current state of the art. The strengths and limitations of each technique to measure microbial samples are given alongside suggestions for future developments.
This document is intended as a guide and a starting point to more specific activities of ISO/TC 201, Surface chemical analysis, in the future, which end in standardized procedures for measurements.

Basic considerations for the safety of hydrogen systems
Käsitlusala:
ISO/TR 15916:2015 provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). It identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards.
"Hydrogen" in this paper means normal hydrogen (1H2), not deuterium (2H2) or tritium (3H2).

Laboratory furniture - Recommendations for design and installation - Part 5: Services distribution carriers
Käsitlusala:
This document is applicable to biology, chemistry and physics laboratories where research, preparative, analytical, process activities take place and which can involve work with hazardous substances, including higher education (college and university teaching and post-graduate research).
This document does not cover the requirements of schools, i.e. precollege/pre-university (refer to EN 13150), or highly specialist laboratories which need very specific, bespoke solutions to enable them to function.
This document specifies requirements for various types of services distribution carriers typically used in combination with laboratory bench types as covered in the EN 14056 series. This document gives guidelines for all parties involved in the planning, design, manufacture, installation, testing of a new laboratory or in the refurbishment of an existing laboratory.
