The BS is influenced by the major manufacturers as they sit on the committee via the trade bodies & they did indeed influence the standard by forcing the dropping of the requirement to reject extinguishers with incorrect colour coding namely the eco-foam extinguishers with about 25% green coding on the label & only 5% cream.
Joking aside, the commissioning requirement is welcome as I have come across some terrible examples of incorrectly or incompletely assembled internet supplied extinguishers, plus when eventually the user gets caught & is required to have them serviced, there is no information on weight to check against (except CO2) and age (not all non CO2 bodies manufactured in the past are stamped with manufacture date in the base ring).
The tongue in cheek bit does reflect that sections of the industry freely admit they are hurt by the price drops brought in by internet suppliers & anything to try and curtail them is welcome.
What the latest amendment doesn't do is filter out the low quality kit or deal with maintainers who don't requalify - some people servicing aren't aware of the 2000 or 2003 versions & I know one who doesn't know halon is illegal.
