115.Materials tests may be required to be carried out to establish the quality and strength of a material to confirm that it is suitable for compliance with building regulations. This section makes provision for verifiers and the Scottish Ministers to require specified persons to carry out a test of materials in specified circumstances. Ministers may require such tests to be carried out only after an application has been made to them under section 3 for a direction dispensing with or relaxing a building regulation. Verifiers may require such tests to be carried out by those who have applied for a building warrant under section 9, by those who have submitted a completion certificate under section 17 and by those who are constructing a building in pursuance of a building warrant.
