This European Standard provides a guideline on the implications fo choice of particle metric to express the exposure to nanoaerosols, presents the principles of operation, advantages and disadvantages of various techniques that measure these aerosol metrics and desribes potential problems and limitations.

This European Standard specifies the use of different metrics for the measurement of exposure by inhalation of NOAA during a basic assessment and a comprehensive assessment, respectively, as described in EN 17058 [1].
This document demonstrates the implications of choice of particle metric to express the exposure by inhalation to airborne NOAA, e.g. released from nanomaterials  and present the principles of operation, advantages and disadvantages of various techniques that measure the different aerosol metrics.
Potential problems and limitations are described and need to be addressed when occupational exposure limit values might be adopted in the future and compliance measurements will be carried out.
Specific information is mainly given for the following metrics/measurement techniques:
-   Number/Condensation Particle Counters by optical detection;
-   Number size distribution/differential mobility analysing systems by electrical mobility;
-   Surface area/electrical charge on available particle surface;
-   Mass/chemical analyses (e.g. Inductively Coupled Plasma atomic Mass Spectrometry (ICP-MS), X-Ray Fluorescence (XRF)) on size-selective samples (e.g. by impaction or diffusion).
This document is intended for those responsible for selecting measurement methods for occupational exposure to airborne NOAA.

This European Standard specifies the medium access control/physical layer MAC/PHY and networking layer of a communication protocol for the exchange of data from metering devices to other devices within a mesh network.
The referenced documents in this European Standard contain specifications, interface descriptions, object descriptions, protocols and algorithms pertaining to this protocol standard, the device objects, device profile, the application framework, the network layer, and security services.
They are referenced in their entirety for reasons of backwards compatibility and interoperability with products in the field currently using this technology.

This European Standard specifies the application layer of a communication protocol for the exchange of data from metering devices to other devices within a mesh network. This European Standard makes reference to a number of documents whereby core requirements are specified. This referencing is in compliance with the Bridge Consortium and additionally the Memorandum of Understanding between the ZigBee Alliance and CEN/CENELEC.
The EN 16836 series represents a feature subset of a larger standard and as such not all of the features specified in the referenced documents are specified in this standard, due to some features being outside the scope of CEN/TC 294. Where this is the case the out of scope feature has either been omitted or specified as excluded.

This European Standard gives the standardization framework of communication systems applicable to the exchange of data from metering devices to other devices within a mesh network.
This European Standard specifies how to interpret prEN 16836-2:2015 and prEN 16836-3:2015 which give a list of references to the ZigBee documents. This series is applicable to communications systems that involve messages and networking between a meter or multiple meters and other devices in a mesh network, such as in home displays (IHDs) and communications hubs. This European Standard allows routing between devices and also allows channel agility to avoid contention with other networks of the same type, or indeed networks of other types operating in the same frequency bands.
This European Standard is designed to support low power communications for devices such as gas and water meters which can make data from such devices available on the mesh network at any time through a proxy capability within a permanently powered device.
