CEN/TS 14383-2:2022(Main)
Crime prevention through building design, urban planning and city maintenance - Part 2: Principles and process
SIST-TS CEN/TS 14383-2:2023

This document establishes general principles and specifies the framework for a process of Crime Prevention Through Environmental Design (CPTED).
It specifies the assessment of risk of crime problems (crime and/or feelings of insecurity) and the framework, process, measures and procedures aimed at reducing these risks in a specific new to build or existing environment. The crimes covered by this document are often of an opportunistic nature and are crimes against property (e.g. burglary, theft, vandalism, pickpocketing, arson), violent crimes (e.g. assaults, robbery, terrorism, harassment, sexual violence) as well as other criminal behaviour (see Annex A). The exact choice of which types of crime will be included in an approach has to be taken locally and is part of the processes and procedures described in this document. Annex A gives an overview of all foreseeable types of crime in all European languages. Feelings of insecurity are also defined as a ‘crime problem’ in this document.
This document provides guidelines and strategies for a CPTED-process in specific types of environments to prevent or reduce the risks of potential or identified crime problems. Guidelines for a step-by-step process are given to involve all stakeholders engaged in urban planning and environmental crime reduction. It also allows for all other stakeholders to be engaged – mainly local and regional authorities and residents/businesses/institutes – in the multi-disciplinary action needed to minimize the risks of crime problems (crime and feelings of insecurity).
This document introduces a process that is applicable to the planning process of new, as well as existing, urban areas. Such an area can be the neighbourhood or environment ranging from just one building to a few buildings or streets to a whole district. This document also introduces a higher-level framework that is often city wide – or regional or sometimes even national – and democratically legitimised for regular implementing CPTED in specific areas and for specific (new/existing) urban planning, design and management projects.
This document provides all relevant actors with guidelines aimed at reducing or managing the risk of crime problems in a specific defined environment.

Secure storage units - Classification for high security locks according to their resistance to unauthorized opening - Distributed systems
SIST EN 17646:2022

This document is applicable to Distributed Systems (DS), i.e. high security locks with components which have a wired or wireless connection via a transmission system in order to execute fixed operating conditions using different individually fixed access possibilities.
Products which are to be tested on the basis of this document comply with the generally recognized state of the art at the time of testing. Due to the short innovation cycles in the field of electronic and, in particular, information technology applications, the technical possibilities available at the time of product development should also be taken into account during implementation.
Distributed systems can be used, for example, to operate high security locks of secure storage units (safes and strongrooms).
High security locks (HSL) are used in DS as locking unit.
This document does not apply for stand-alone HSL, which are not part of a distributed system. For these stand-alone HSL EN 1300 is applicable only.
The document will be revised with a frequency of 3 years as the research in the area of cryptography and relevant attacks evolve with high speed as well as the referenced standards.
