From “Wikipedia: ISO 3103“:

ISO 3103 is a standard published by the International Organization for Standardization (commonly referred to as ISO), specifying a standardized method for brewing tea. It was originally laid down in 1980 as BS 6008:1980[1]. It was produced by ISO Technical Committee 34 (Food products), Sub-Committee 8 (Tea).

Funny! I’m sure Mr. Rose is a fervent adept.
