ISA batch control standard released as an IEC PAS

Batch control, consistency, and quality control within and among facilities will become easier, as a result of streamlined ISA/IEC cooperation. An ISA standard widely used for batch control has been released as an IEC PAS (Publicly Available Specification), thanks to a joint effort by the Instrumentation, Systems, and Automation Society and the International Electrotechnical Commission.

ANSI/ISA-88.00.03-2004, Batch Control Part 3: General and Site Recipe Models and Representation , defines a model for general and site recipes. In principle, the recipes can be duplicated at any plant, allowing manufacturers with multiple plants to be consistent in production quality. Industry recognizes this concept as important for promoting manufacturing efficiency, keeping production costs down, and maintaining satisfied customers, according to ISA.

Collaboration with IEC on the ISA-88 standard series is one way ISA works to develop industry standards. The organization is accredited by the American National Standards Institute (ANSI) and has published more than 135 standards, recognized practices, and technical reports through the input and efforts of an international network of industry experts. The recognized standards writing organization has developed consensus standards for automation, security, safety, batch control, control valves, fieldbus, environmental conditions, measurement, and symbols.

IEC PASs offer valid guidance in a shorter time than consensus-based international standards. They are expected to be transformed into IEC International Standards within a few years. IEC PASs developed as a response to industry’s request for quicker standardization in areas of rapidly developing technology.
