I dont know anything about British Standard but I noticed for the most part that the locks you listed as BS have a metal plate with the shape of the letter H cut into them and they look like they ride up and down. Can you explain its purpose or explain what are the requirements for a lock to be certified BS?
Thank You,

Those plates are actually the levers Squelch. Instead of pivoting about a fulcrum they slide up and down.
Specification BS3621 was launched in the 1960’s to regulate security on domestic and commercial property. Many of the requirements still stand today having revised the BS3621 standard in 2004 to bring the specification up to date which included a change in bolt length from 14mm to 20mm.
BS3621: an insurance standard for locks, specifying, for example, the minimum number of differs,minimum 5 levers and that there is protection against drilling and sawing, and that the strike box is metal (equivalent to the European standard EN12209)
