This document specifies a method for the determination of the inhibition of growth of the unicellular marine algae Skeletonema sp. and Phaeodactylum tricornutum by substances and mixtures contained in sea water or by environmental water samples (effluents, elutriates, etc.).
The method can be used for testing substances that are readily soluble in water and are not significantly degraded or eliminated in any other way from the test medium.
NOTE With modifications, as described in ISO 14442 and ISO 5667–16, the inhibitory effects of poorly soluble organic and inorganic materials, volatile compounds, metal compounds, effluents, marine water samples and elutriates of sediments can be tested.

This part of ISO 9241 gives recommendations for tactile/haptic hardware and software interactions. It provides guidance on the design and selection of hardware, software, and combinations of hardware and software interactions, including
— the design/use of tactile/haptic inputs, outputs, and/or combinations of inputs and outputs, with general guidance on their design/use as well as on designing/using combinations of tactile and haptic interactions for use in combination with other modalities or as the exclusive mode of
interaction,
— the tactile/haptic encoding of information, including textual data, graphical data and controls,
— the design of tactile/haptic objects,
— the layout of tactile/haptic space, and
— interaction techniques.
For guidance and recommendations on the accessibility of tactile/haptic interactions, including information on the use of braille, see ISO 9241-971. It does not provide recommendations specific to braille but can apply to interactions that make use of braille.
The recommendations given in this part of ISO 9241 are applicable to a variety of tactile/haptic devices, representing the real world or virtual or mixed realities (e.g. exoskeletons, wearables, force feedback devices, touchables, tangibles) and stimulation types (e.g. acoustic radiation pressure, electrical muscle stimulation) and they can also be found in virtual and augmented environments.
This document does not include guidance on the role of walking in virtual or mixed realities for tactile/ haptic interaction.
NOTE It is recognized that some interactive scenarios might be constrained by the limitation that a real workspace is to be modelled in a virtual environment. Objects can be in suboptimal positions or conditions for
tactile/haptic interaction by virtue of the situation being modelled.
This document provides general information about how various forms of interaction can be applied to various user tasks. The use of gestures (e.g. multitouch) can be found in ISO 9241-960. Information on gesture-based interfaces can be found in the multipart standard ISO/IEC 30113. Information on contactless gestures can be found in ISO TS 9241-430.

This document covers the test method for measuring hazardous substances emitted during the operation of material extrusion type 3D printer in the non-industrial places and considerations for reducing them.
This document:
— specifies main hazardous substances emitted from material extrusion type 3D printer during operation;
— describes the additional information and the associated test method for measuring hazardous
substances, and;
— includes considerations for reducing the hazardous substances and basic countermeasures.
This document is to measure concentrations of hazardous substances generated in the non-industrial places (school, public place and so on) in which material extrusion type 3D printers are installed, and to maintain an acceptable work environment by managing field facilities, material extrusion type 3d printers, filaments, and additive manufactured products for the reduction of hazardous substances.
However, this document does not cover all gas-phase chemical emissions but are applicable to a range of VOCs from n-hexane to n-hexadecane, including aldehydes. Considerations for reducing chemical
emissions and for improving the work environment are given in Annex A and B.

This document presents a protocol for the application of semi-quantitative Wavelength Dispersive X-Ray Fluorescence Spectrometry (WD-XRFS) commercial packages for assessment of the concentration of
rare earth elements (REEs) contained in magnet scrap from End of Life (EOL) products intended for recycling.
The standard can be subdivided into two parts:
1. The first part outlines a procedure for safe handling of the magnet scrap
2. The second part specifies measurement of the REE content in the magnet scrap
WARNING — The use of this document may involve hazardous materials, operations, and equipment. This document does not purport to address any safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The concentration ranges of samples that may be appropriately analyzed by this method are given in
Tables 1, for each type of magnet scrap included in the standard.

NOTE Standardless XRF analysis will be carried out on all the elements between Na and U. The final report will contain the elements in scope that are over 1 mass %.
