Introduction

This document presents the changes introduced in the testing procedures (hereinafter ACT rules) that exist as implementations of the Accessibility Conformance Testing (ACT) Rules Format 1.1 specification.

These rules were originally written in accordance with requirements introduced in ACT Rules Format 1.0, and have now been updated to conform with the requirements introduced in ACT Rules Format 1.1.

Note: The ACT rules Format 1.1 supports "subjective applicability" but this is not a requirement. On the contrary, it gives more flexibility to rule authors in case they think their testing procedures would benefit from subjective applicability.

Implemented changes in ACT Rules Format 1.1

The below is a breakdown of all normative changes introduced in ACT Rules Format 1.1 as well as the rules that have been updated to conform with these changes.
