British Standards Institution

Sector: Sustainability

Overview: Under the direction of the Standards Policy and Strategy Committee, is responsible for the UK input to ISO/TC 180 and CEN/TC 312 and for standards affecting the use of solar heating, having regard to technical and legislative aspects both in the UK and EU. It is also responsible, under the direction of the British Electro-technical Committee (BEC) for the UK input to IEC/TC 117 and CLC/SR 117
