Overview: Under the direction the Standards Policy and Strategy Committee, is responsible for standardization activities in the field of Fine Bubble Technology (FBT). Its aims are to: a) ensure that UK interests are represented at all stages of the development International Standards through the submission of written comments and, as appropriate, by attendance at meetings of the corresponding International technical committee ISO/TC 281.
