IEC SRD 63347-2:2026 describes and analyses a comprehensive set of high-level scenarios of how smart cities can best respond to public health emergencies, and strengthen their “Urban Immune System”, using evidence from as many countries as possible. It covers use cases related to the prevention, the control and the successful ending of public health emergencies, and to dealing with the longer-term harm that these may cause. It considers a wide range of different scenarios and reviews both the management challenges and the range of technology solutions, including the use of IoT, 5G, AI, Big Data, and Cloud Computing, available in each of them, in order to provide a comprehensive outline of the standardization requirements to develop an effective Urban Immune System. The public health emergencies envisaged are those relating to pandemics resulting from novel forms of disease, for which there is no natural immunity within the population and no tried and tested treatment. However, some of its provisions will be helpful to dealing with pandemics of existing diseases such as typhoid and cholera brought on through natural disasters or war. This document will provide useful information to International and national Standards Development Organizations and thus facilitate and promote the development of the smart city standards required.

This part of IEC 62676 specifies the functions, performance, interfaces, environmental adaptability, test methods, performance evaluation and grading rules of real-time intelligent video analysis in surveillance systems.
This document applies to live and forensic, real-time intelligent video analysis devices and systems in video surveillance.
The document is centred on testing performance and grading device functionality which enables:
• Core capability: Classification of objects, detection of specific "object activity", such as "stopping", "starting", "direction of movement", etc.
Examples are listed in Annex A.
• Complex capability: Detection of "scenarios" which are based on combinations of object activity, such as "loitering", "perimeter intrusion detection", "person down", "tailgating", "intrusion", "abandoned object detection", explosion, fire, flood, potential terrorist attack using a vehicle, owner of an abandoned bag, etc.
Examples of current scenarios are listed and described in Annex B.
• Degree of difficulty: The application of real operating environments to test the performance under known or required operating stress levels, examples of operating stress levels that are sterile or non-sterile, indoor or outdoor, target obscuration levels, extreme weather conditions, vibrating mechanical rugged environments causing image shake resulting in degradation of image quality requirement, see Table 1 and Annex C.
The purpose of this document is to provide end users, at different levels of the service process, from users and installers, integrators and maintenance companies, to certification providers, with methods to measure the performance of video analysis systems that must also comply with other parts of the standard.

This document gives guidance on the procedure for the bioaccumulation of substances liable to cause atmospheric pollution. This is done by using the grass species Lolium multiflorum ssp. italicum designated hereafter as Italian rye-grass. It is an active biomonitoring approach insofar as the plants used are first cultivated in set conditions before being exposed at the monitoring locations in the field. The plants then record any pollution events that occur while they are being exposed, allowing such events to be accurately dated.
The document specifies a method for identification and localization of one or more single pollution sources and the tracking of their "plume" on a local or regional scale. The method described also offers a tool to monitor sites in the long term by the repeated application of a clearly defined procedure and to describe the local or regional air pollution situation.
The method described in this document is applicable to solid and gaseous substances deposited on plants, where they can accumulate on their surface or in their tissues. These substances include sulphur, chloride, fluoride and especially metals as well as low volatile organic and halo-organic compounds such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), polybrominated diphenyl ethers (PBDE), polychlorinated dibenzo dioxins (PCDD) and polychlorinated dibenzo furans (PCDF). It is as well possible to verify pesticides which are used in plant protection products. The range of potential substances can be expanded according to the task at hand and the capabilities of conducting trace analyses and assessment.
The method described in this document allows spatial and temporal comparisons and allows for screening, thus providing a first indication of risk. The results of grass culture studies can suggest risks to biota (e.g. via the food chain) which require further investigation.
The method described in this document does not replace physico-chemical methods of direct measurement or modelling of air pollutants and cannot be replaced by them for its part; it complements them by indicating biological effects.
Potential areas of deployment are:
-   permit procedures related to air pollution legislation;
-   preservation of evidence related to the code for protection from pollution;
-   monitoring of emission sources and performance control;
-   assessment of local-scale emission transport;
-   evidence of causation, e.g. related to environmental liability;
-   air quality maintenance plans/strategies;
-   long-term monitoring of ecological effects of atmospheric depositions;
-   detection and assessment of local, regional, and countrywide effects of atmospheric depositions;
-   assessment of risks for humans and/or animals via the food chain.
This document is of interest to those involved in environmental monitoring.

This document specifies the cloud computing reference architecture (CCRA).
