This European Standard is a service standard that specifies requirements for quality in organization, processes, staff and management of a security services provider and/or its independent branches and establishments under commercial law and trade as a provider with regard to port and maritime security services. This European Standard applies according to the laws and the regulations applicable in the territory of every national CEN member adopting the standard. This European Standard does not apply to security services provided by private security companies that are subject to particular rules and conditions and/or related to a specific high-risk situation and/or the use of heavy weapons and/or special training and/or government supervision, such as security services in relation to piracy. In case such particular rules and/or conditions do not exist at national level, this European Standard can apply. This European Standard lays down quality criteria for the delivery of security services in and to ports and in relation to maritime activities, requested and contracted upon by public and private clients or buyers. This European Standard is therefore suitable for the selection, attribution, awarding and reviewing of the most suitable provider for port and maritime security services.
