I don't think anyone has suggested that it does.
As far as I can make out, the 3.15 A fuses (and max 6 sockets) probably arise from BS6396 (for 'Office Furniture')

They do -although, as has been said (and as you will surely agree) that may be 'incorrect'.
However, in common sense terms, if they are used in a kitchen, the standard for 'Office Furniture' (BS6396) isn't really appropriate/relevant, and it seems that it is that Standard which results in the 3.15A fuses. Indeed, it's far from impossible that the Standard actually says that it only applies to things "when used in an office".
I wonder how long this silly BS6396 has been around. Certainly when I worked in offices the 13a sockets were not fused at 3.15a. We had an office kettle for making a cuppa. There was even an office microwave.
Seemingly since 2008, but there is now a 2022 version.

Not sure, but the specification for this product does clearly state it is intended for offices and is designed that way for BS6396, so that's that.
I don't know if part of the reason for it is to discourage the use of kettles and toasters near electronic office equipment - I'm not looking it up!!
Anyone found a suitable 13amp fuse?
As has been said, 12.5A ones seem to be fairly available from reputable sources.
In passing, does anyone know how/why these 3.15A fuses (and, indeed, 315 mA ones) came into being?
Kind Regards, John
Case 146 - Kettles banned in office as this would encourage staff to walk around with open topped cups
An office has been denied the use of a kettle due to health and safety. The enquirer referred to Case 69 on Myth Busters Webpage whilst challenging this decision with office managers.

BS6396 is specifically for items of office furniture with integrated electrical wiring for e.g. built-in lighting. It also allows for power sockets for convenience, but limits the current to any item to 5A. As such it is making no statement about electrical outlets separate from the furniture.

Have you lost the will to live yet? I have. But I have been googling on your behalf.
This one has what you want, and it is in stock and it hasnt any fuses to argue about....

Thank you, yes.
Since about 2010 we have bought many desks with built-in cable management and extension leads - they are a pain.
Excluding the 3.15A fuse issue, which do get blown - frequently, they are horrible to PAT.
With the extension hidden under a flap at the back of the desk, the flap inevitably gets covered with academic detritus!
We usually supply a separate extension, and 'red label' the built-in lead!

It's a Renard's Series number in the ISO R10 series.
True, in terms of the "least rounded" version of the ISO R10 series. The electrical world more commonly used the "medium rounded" or "most rounded" versions, which is presumably the reason why we have 32A MCBs etc, rather than 31.5A ones, 6A MCBs rather than 6.3A ones, and 1.5 mm² cables rather than 1.6 mm² ones.
Put in less formal terms, the convention for 'current ratings' of things (including fuses) which are ≥1A seems to be that they are usually rounded to the nearest whole number, with no more than 2 significant digits, which is why 3.15A fuses have always surprised me a bit, particularly since it seems to be a fairly unique exception to that 'conventional rounding rule'.
In practical terms, none of this matters in the slightest but, as I said, I've always wondered about it.
Kind Regards, John
and thus increase the risk of the self-immolation of a power module built like a 13 Amp plug but lacking a fuse.
If you care to read the topic (post #1 is a good starting point) you will discover that the requirement is for a kitchen island worktop not an office desk. I imagine this would be for occasional use and not permanently popped up.
But why can you not make a positive contribution, rather than constantly finding problems with others helpful suggestions???
I did say increase the risk,
Yes a 750 Watt supply could cause a fire in a faulty power module. but during the early seconds of that fire internal damage could create a fault path Live to Neutral and allow enough current to blow the 3.15 Amp fuse, The same internal fault path may not be "strong" enough to rupture a higher rated fuse and thus there would be far more than 750 Watts of heating persistently inside the power module.,
