Calum has tested to many international and national standards following the many requirements and conditions required by these.  Calum has written and reviewed test procedures for various test types to conform with the standards.  The standards he has tested to have included heat pumps and other refrigeration systems for capacity and noise levels where applicable.

To conduct testing to new testing methods, or innovative products, he has been involved in the specification, building, and providing the testing in various test locations and types for Clients.  He has been involved and managed many different size projects within BSRIA for heat pumps and mock-ups and liaised with Clients throughout these.
