IEC 62682

Last updated

IEC 62682 is a technical standard titled Management of alarms systems for the process industries.



The standard specifies principles and processes for the management of alarm systems based on distribute control systems and computer-based Human-Machine Interface (HMI) technology for the process industries. It covers alarms from all systems presented to the operator, which can include basic process control systems, annunciator panels, safety instrumented systems, fire and gas systems, and emergency response systems. The practices are applicable to continuous, batch, and discrete processes. The process industry sector includes many types of manufacturing processes, such as refineries, petrochemical, chemical, pharmaceutical, pulp and paper, and power.

The Standard

The standard addresses all lifecycle phases (development, design, installation, and operation) for alarm management in the process industries. The standard defines the terminology and work processes recommended to effectively maintain an alarm system throughout the lifecycle. The standard was written as an extension of the existing ISA 18.2-2009 standard which utilized numerous industry alarm management guidance documents in its development such as EEMUA 191. Ineffective alarm systems have often been cited as contributing factors in the investigation reports following major process incidents. The standard is intended to provide a methodology that will result in the improved safety of the process industries.

Alarm management is the application of human factors along with instrumentation engineering and systems thinking to manage the design of an alarm system to increase its usability. Most often the major usability problem is that there are too many alarms annunciated in a plant upset, commonly referred to as alarm flood, since it is so similar to a flood caused by excessive rainfall input with a basically fixed drainage output capacity. However, there can also be other problems with an alarm system such as poorly designed alarms, improperly set alarm points, ineffective annunciation, unclear alarm messages, etc. Poor alarm management is one of the leading causes of unplanned downtime, contributing to over $20B in lost production every year, and of major industrial incidents such as the one in Texas City. Developing good alarm management practices is not a discrete activity, but more of a continuous process. ==

Systems engineering interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful function.

A management system is a set of policies, processes and procedures used by an organization to ensure that it can fulfill the tasks required to achieve its objectives. These objectives cover many aspects of the organization's operations. For instance, an environmental management system enables organizations to improve their environmental performance and an occupational health and safety management system (OHSMS) enables an organization to control its occupational health and safety risks, etc.

Fieldbus Foundation was an organization dedicated to a single international, interoperable fieldbus standard. It was established in September 1994 by a merger of WorldFIP North America and the Interoperable Systems Project (ISP). Fieldbus Foundation was a not-for-profit trade consortium that consisted of more than 350 of the world's suppliers and end users of process control and manufacturing automation products. Working together those companies made contributions to the IEC/ISA/FDI and other fieldbus standards development.

Safety integrity level (SIL) is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a safety instrumented function (SIF).

Cybersecurity standards are techniques generally set forth in published materials that attempt to protect the cyber environment of a user or organization. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks. The principal objective is to reduce the risks, including prevention or mitigation of cyber-attacks. These published materials consist of collections of tools, policies, security concepts, security safeguards, guidelines, risk management approaches, actions, training, best practices, assurance and technologies.

The ISO/IEC 15288 is a systems engineering standard covering processes and lifecycle stages. Initial planning for the ISO/IEC 15288:2002(E) standard started in 1994 when the need for a common systems engineering process framework was recognized. The previously accepted standard MIL STD 499A (1974) was cancelled after a memo from SECDEF prohibited the use of most United States Military Standards without a waiver. The first edition was issued on 1 November 2002. Stuart Arnold was the editor and Harold Lawson was the architect of the standard. In 2004 this standard was adopted as IEEE 15288. ISO/IEC 15288 has been updated 1 February 2008 as well as on 15 May 2015.

ISO/IEC 21827 is an International Standard based on the Systems Security Engineering Capability Maturity Model (SSE-CMM) developed by the International Systems Security Engineering Association (ISSEA). ISO/IEC 21827 specifies the Systems Security Engineering - Capability Maturity Model, which describes the characteristics essential to the success of an organization's security engineering process, and is applicable to all security engineering organizations including government, commercial, and academic. ISO/IEC 21827 does not prescribe a particular process or sequence, but captures practices generally observed in industry. The model is a standard metric for security engineering practices covering the following:

Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner (fail-safe). The automatic protection system should be designed to properly handle likely human errors, hardware failures and operational/environmental stress.

Control system security is the prevention of interference with the proper operation of industrial automation and control systems. These control systems manage essential services including electricity, petroleum production, water, transportation, manufacturing, and communications. They rely on computers, networks, operating systems, applications, and programmable controllers, each of which could contain security vulnerabilities. The 2010 discovery of the Stuxnet worm demonstrated the vulnerability of these systems to cyber incidents. The United States and other governments have passed cyber-security regulations requiring enhanced protection for control systems operating critical infrastructure.
