IEC 62646:2016为设计者希望计算机化的操作程序的整个生命周期制定了要求。它还为决定哪些类型的程序应该计算机化以及计算机化到什么程度提供了指导。一旦计算机化，程序被指定为“基于计算机的程序”（CBP）。与上一版相比，新版本包括以下重大技术变化:澄清了标准与相关标准结合使用的方式。 本出版物应与IEC 60964:2009和IEC 61839:2000一起阅读。

IEC 62646:2016 establishes requirements for the whole life cycle of operating procedures that the designer wishes to computerise. It also provides guidance for making decisions about which types of procedures should be computerised and to what extent. Once computerised, procedures are designated as "computer-based procedures" (CBP). This new edition includes the following significant technical changes with respect to the previous edition: clarification of the way in which the standard is to be used in conjunction with related standards.

This publication is to be read in conjunction with IEC 60964:2009 and IEC 61839:2000.
