ISO 50001:2011/ TC 242 Energy Management

ISO 50001:2011 specifies requirements for establishing, implementing, maintaining and improving an energy management system, whose purpose is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy use and consumption.

ISO 50001:2011 specifies requirements applicable to energy use and consumption, including measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel that contribute to energy performance.

ISO 50001:2011 applies to all variables affecting energy performance that can be monitored and influenced by the organization. ISO 50001:2011 does not prescribe specific performance criteria with respect to energy.

ISO 50001:2011 has been designed to be used independently, but it can be aligned or integrated with other management systems.

ISO 50001:2011 is applicable to any organization wishing to ensure that it conforms to its stated energy policy and wishing to demonstrate this to others, such conformity being confirmed either by means of self-evaluation and self-declaration of conformity, or by certification of the energy management system by an external organization.

ISO 50001:2011 also provides, in Annex A, informative guidance on its use.


ISO 22301:2012, Societal security – Business continuity management systems – Requirements

ISO has published an International Standard addressing business continuity management to contribute making organizations in both public and private sectors more resilient.

ISO 22301:2012, Societal security – Business continuity management systems – Requirementswill help organizations, regardless of their size, location or activity, to be better prepared and more confident to handle disruption of any type.

Incidents can disrupt an organization at any time and applying ISO 22301 will ensure that organizations can respond and continue its operations. Incidents take many forms ranging from large scale natural disasters and acts of terror to technology-related accidents and environmental incidents. However, most incidents are small but can have a significant impact and that makes business continuity management relevant at all times.

This has led to a global awareness that organizations in the public and private sectors must know how to prepare for and respond to unexpected and disruptive incidents.

ISO 22301 provides a framework to plan, establish, implement, operate, monitor, review, maintain and continually improve a business continuity management system (BCMS). It is expected to help organizations protect against, prepare for, respond to, and recover when disruptive incidents arise.

ISO 22301 will assist organizations in the design of a BCMS that is appropriate to its needs and meets its stakeholders’ requirements. These needs are shaped by legal, regulatory, organizational and industry factors, the organization's products and services, its size and structure, its processes, and its stakeholders.

ISO 22301 is the first standard published which is aligned with the new ISO format for writing management systems standards. This will ease understanding and ensure consistency with other management systems, such as ISO 9001 (quality management), ISO 14001 (environmental management) and ISO/IEC 27001 (information security management).

ISO 22301 may be used for third-party certification as well as for self assessment. To help users get the best out of the standard, it includes short and concise requirements describing the central elements of BCM.

Given the role of business continuity in every sector, ISO 22301 has a huge worldwide potential. So far, numerous countries have started to adopt ISO 22301, including Singapore and United Kingdom to replace their existing national standards. There is already interest from business worldwide who wish apply good practice and obtain certification against this standard. This attests to its vast potential user base and expected benefits.

ISO 22301 is part of a series of standards developed by ISO technical committee ISO/TC 223, Societal security. For example, an additional document is under development called ISO 22313 which is expected to be published early next year. This companion standard contains guidance for implementing the ISO 22301.

ISO 22301:2012, Societal security – Business continuity management systems – Requirements, is available from ISO national member institutes (see the complete listwith contact details). It may also be obtained directly from the ISO Central Secretariat, price 116 Swiss francs respectively through the ISO Store or by contacting the Marketing, Communication & Information department.

IEC/TC56 Dependability

The purpose of TC 56 is to prepare international standards in the field of Dependability, in all appropriate technological areas. Dependability is the ability to perform as and when required and is time dependent in application. Dependability can be expressed in terms of core attributes of availability, reliability, maintainability and supportability that are tailored to application-specific functional and service attributes. The standards provide systematic methods and tools for the dependability assessment and management of equipment, services and systems throughout their life cycles.

Dependability standards cover generic aspects on dependability program management, testing and analytical techniques, software and system dependability, life cycle costing and technical risk assessment. This includes standards related to product issues from component reliability to guidance for engineering dependability of systems, standards related to process issues from technical risk assessment to maintainability and supportability and standards related to management issues from dependability management to managing for obsolescence. The application of these standards may raise safety related issues, though the standards themselves do not cover safety specifically.

TC 56 has the following working groups which act as maintenance teams for existing standards and support the work on new standards by providing experts who have experience in dependability applications and standard development:

WG1 Definitions - maintains and develop standards on terminology and symbols. WG1 maintains chapter 191 on Dependability definitions in IEC 60050. Definitions are crucial for clear communications, for example in contract situations, and for writing clear and unambiguous standards.

WG2 Methods - maintains and develops standards on test and analysis methods with the associated statistical procedures for these methods (applied statistics). WG2 covers the range from components to complex systems including dependability aspects of software.

WG3 Management - maintains and develop standards for management of Dependability as well as standards on maintainability, maintenance support, technological risk and human aspects.

WG4 Systems - maintains and develops standards on system and network dependability.

ISO TC 224 Assessment of water services

ISO TC 224 - Service activities relating to drinking water supply systems and wastewater systems - Quality criteria of the service and performance indicators. 

The scope of the technical committee is:
Standardization of a framework for the definition and measurement of service activities relating to drinking water supply systems and wastewater systems.

The standardization includes the definition of a language common to the different stakeholders, the definition of the characteristics of the elements of the service according to the consumers expectations, a list of requirements to fulfil for the management of a drinking water supply system and a wastewater system, service quality criteria and a related system of performance indicators, without setting any target values or thresholds.

  • design and construction of water supply and wastewater systems, or maintenance techniques;
  • limits of acceptability for drinking water quality and wastewater discharged in the receiving body;
  • analytical methods.

The technical committee was created in 2001 and formed four working groups:

  • WG 1 - Terminology - oversees the use of terminology within the standards developed by the working groups.
  • WG 2 - produced ISO 24510 - Activities relating to drinking water and wastewater services -- Guidelines for the assessment and for the improvement of the service to users.
  • WG 3 - produced ISO 24512 - Activities relating to drinking water and wastewater services -- Guidelines for the management of wastewater utilities and for the assessment of wastewater services.
  • WG 4 - produced ISO 24511 - Activities relating to drinking water and wastewater services -- Guidelines for the management of drinking water utilities and for the assessment of drinking water services.

In December 2007, on the completion and publication of the three standards, the technical committee decided to undertake three new work items and formed three additional working groups:

  • WG 5 - Implementation: continues to work and is documenting examples of the application of 2451X Standards.
  • WG 6 - Asset Management: is currently working on developing a technical report on asset management best practices for both water and wastewater services.
  • WG 7 - Crisis management of water utilities: is currently working on developing a standard to provide guidance on crisis management activities specific to water utilities.

Update on the ISO 224 Working Group 7 - August 2011
WG 1 - Terminology: continues to oversee the use of terminology in the standards under development.
In August of 2010, the technical committee resolved to open two additional new work items and formed two additional working groups:

  • WG 8 - Onsite domestic wastewater management using low level technologies: is beginning to document low level (simple) technologies for on-site domestic wastewater treatment.
  • WG 9 - Decision support systems: is beginning to develop a framework for assessing decision support systems being offered to water utilities to decide on treatment activities necessary to respond to regular and unexpected source water challenges.

S250 Mapping of Underground Utility Infrastructure (PDF EN 2421375)

This Standard specifies mapping requirements for the recording and depiction of underground utility infrastructure and related appurtenances at or below grade. This Standard does not apply to utility infrastructure that is normally above grade (e.g., overhead wires, pole-mounted transformers, antennas, and dishes).

This Standard applies to proposed, existing, abandoned in-place, retired, or reserved for future use, underground utility infrastructure. This Standard applies to the generation, storage, distribution, and use of mapping records to ensure that underground utilities are readily identifiable and locatable. Application of this Standard will ensure that accurate information about the location and nature of the underground utility infrastructure is captured and available for future projects.
