The only current British Standards referrencing 'pixel' that I am aware of is BS ISO/IEC 9636-6:1991:
Information technology. Computer graphics. Interfacing techniques for dialogues with graphical devices (CGI). Functional specification. Raster.
Describes those functions of the interface concerned with creating, modifying, retrieving, and displaying portions of an image stored as pixel data. Annexes A and B form an integral part of this standard. Annexes C, D, E and F are for information only.
Note: the 'BS' is for British Standards; the ISO/IEC means that the BS is identical to the 'ISO' (International Standards Associaton), 'IEC' (International Electrotechnical Commission) standards of the same number; the 9636-6 means standards 9636-1 through 9636-6 inclusive. The standards are available for a significant payment for those who like reading such things.
The simple answer is 'a pixel is a pixel and has been since 1991' on the world's commercial hardware.
What the client may be referring to is a British Standards 'Kitemark': a logo using the letters 'B' and 'S' looking something like a heart. To North Americans it is something similar to the 'UL', 'ULC', and 'CSA' labels for manufacturers plus the 'ISO' quality programs aimed at various levels of commerce.
Service providers need to have in place a quality plan or quality management system (eg. ISO9001) and be evaluated against specific service criteria as set down in the standard.
If successful, the company earns the right to use the Kitemark in conjunction with its service. To maintain this right, BSI carriers out regular inspections against the standard.
This obviously has nothing to do with 'pixels'.
Perhaps your client is confusing two different programs/standards?

Following on from my original post I’d completely forgotten that PAS78 [bsi-global.com] is actually a BSI product. Maybe this is what they’re talking about? It's a worthy enough document and definitely worth reading through if you're a developer.
