ITU-T P.1501 PDF

This Recommendation describes the methods and procedures used for subjective testing of user perceived quality of web browsing. The method generally applies to degradations and characteristics that can be introduced at the network level (e.g., round-trip time, downlink and uplink bandwidth, packet losses), as well at the application level (e.g., page load-times). Combinations of two or more of these factors also have to be considered. Impacting factors due to webpage design are not in the scope of this Recommendation.
