The ISA Standards & Practices Board and all ISA standards committees have been operating in virtual mode this year and will likely continue to do so for at least the first half of 2021, until a possible face-face meeting at the ISA Annual Leaders Conference, planned for Oct. 2021 in Puerto Rico.

The S&P Board has four ongoing teams working on key goals related to ISA’s overall strategic plan:

SP-1: Committee Effectiveness (Nicholas Sands): Developing job descriptions for new official roles in ISA standards committees, including membership, marketing, social media, and editing, to establish and clarify these roles for committees to fill as desired, and to create a bigger pool of leaders for succession.

SP-2: Board Effectiveness (Eric Cosman): Developing a job description for Board members who serve as Managing Directors of ISA Committees.

SP-3: Portfolio Management (Dennis Zetterberg): Focusing on how to assess older existing standards and technical reports -- and is recommending that the Board establish a permanent portfolio review team.

SP-4: Stakeholder Engagement (Chris Monchinski): Is investigating how ISA sections and divisions are starting to use the new ISA Connect tool to engage their respective members, for possible applicability to ISA standards committees.

IEC Category C liaison organizations have the right to participate as full members in an IEC working group or project team. Category C liaison experts act as the official representative of the organization by which they are appointed. The S&P Board has recently established two new category C liaisons with the IEC:

ISA101, HMI, to IEC SC 65A WG19, HMI, with Greg Lehmann as the official representative from ISA101

ISA88, Batch Control, to IEC MT611512, Batch Control, with Maurice Wilkins as the representative from ISA88.

 In January 2021, a new Vice President of ISA Standards & Practices, Dennis Zetterberg of Chevron, will begin a two-year term, succeeding Chris Monchinski.


Recent ISA S&P Publications:


New ISA99 Standard Provides Auditable Approach to Assessing Cybersecurity Risk

The widely used ISA/IEC 62443 Industrial Automation and Control Systems (IACS) Security standards, developed primarily by the ISA99 standards development committee with simultaneous review and adoption by the International Electrotechnical Commission (IEC), provide a flexible framework to address and mitigate current and future IACS security vulnerabilities.  The ISA99 committee draws on the input and knowledge of IACS security experts from across the globe to develop consensus standards that are applicable to all industry sectors and critical infrastructure.

An important new standard in the series is based on the understanding that each organization that owns and operates an IACS has its own tolerance for risk – and that each IACS represents a unique risk depending on the threats it is exposed to, the likelihood of those threats arising, the inherent vulnerabilities in the system, and the consequences if the system were to be compromised. The new standard, ISA/IEC 62443-3-2: Security Risk Assessment for System Design, defines a comprehensive set of engineering measures to guide organizations through the essential process of assessing the risk of a particular IACS and identifying and applying security countermeasures to reduce that risk to tolerable levels. 

The new standard can be effectively applied across all industry and critical infrastructure sectors that depend on secure IACS operations. Moreover, it provides much-needed guidance to all key stakeholder categories, including asset owners, system integrators, product suppliers, service providers, and compliance authorities.

The standard is the latest in a string of notable milestones in the ongoing development and growing global application of the ISA/IEC 62443 series. This included a decision by the United Nations Economic Commission for Europe to integrate the widely used standards into its Common Regulatory Framework on Cybersecurity, which serves as an official UN policy position statement for Europe. It also included completion of several key additional standards, including:

ISA/IEC 62443-4-1, Product Security Development Life-Cycle Requirements

ISA/IEC 62443-4-2, Technical Security Requirements for IACS Components

Other standards in the ISA/IEC 62443 series cover terminology, concepts, and models; establishing an IACS security program; patch management; and system security requirements and security levels. All may be accessed at .

Updated ISA84 Guidelines for Using ISA/IEC 61511

The ISA84 standards committee, Instrumented Systems to Achieve Functional Safety in the Process Industries, is continuing its comprehensive program of developing and updating set of technical reports providing guidance and practical examples in applying the widely used ISA/IEC 61511-2018 standards, Functional Safety - Safety Instrumented Systems for the Process Industry Sector, Parts 1-3.  Those ISA/IEC standards, the first version of which was completed by ISA84 in 1996, set forth requirements for the specification, design, installation, operation, and maintenance of a safety instrumented system (SIS) so that it can be entrusted to achieve or maintain a safe state of a process.

ISA84 recently completed an update to one of several technical reports on specific phases of the SIS lifecycle.  ISA-TR84.00.04-2020 Part 1, Guidelines for the Implementation of ANSI-ISA-61511-1-2018 (IEC 61511-1), provides an overview of the SIS lifecycle with references to several annexes containing detailed guidance on key aspects of the safety lifecycle, including: “grandfathering” existing SISs, operator-initiated functions, separation of the basic process control system (BPCS) and SIS , field device and logic solver selection, manual shutdown considerations, and design/installation considerations (for example, wiring, power, relationship to BPCS, common mode impacts, and fault tolerance).

Another ISA84 technical report in revision, ISA-TR84.00.02, Safety Integrity Level (SIL) Verification of Safety Instrumented Functions, serves as a tutorial on the fundamentals of data selection and the reliability calculations. The revision is expected to be completed by the end of this year.

This work follows the late 2019 publication of ISA-TR84.00.03, Automation Asset Integrity (AAI) of Safety Instrumented Systems, which presents guidance on establishing an effective AAI program that demonstrates through traceable and auditable documentation that the SIS and its equipment are maintained in an "as good as new" condition.

Previous ISA84 technical reports also include:

ISA-TR84.00.09-2017, Cybersecurity Related to the Functional Safety Lifecycle

ISA-TR84.00.08-2017, Guidance for Application of Wireless Sensor Technology to Non-SIS Independent Protection Layers

ISA-TR84.00.07-2018, Guidance on the Evaluation of Fire, Combustible Gas and Toxic Gas System Effectiveness

ISA-TR84.00.05-2009, Guidance on the Identification of Safety Instrumented Functions (SIF) in Burner Management Systems (BMS)

ISA standards participation and meetings are open to all interested parties, and experts from any country are welcome to join the ISA84 committee.
