What is the tolerance when a DFT is specified?

275 micron is the required DFT for the client; they don't allow less than 240 or more than 350. Please mention the SSPC, BS and ISO standards to allow the + or - variation .

Irrespective of what any official standards quote your client has (for their own requirements) given you the tolerances they are prepared to accept.
Informing your client that these tolerances are not acceptable because some standard states so, would in my opinion alienate them and make them think that your company can�t supply them with the quality of workmanship they desire.
