Which statement best defines the term 'Coverage criteria'?

• A. Rules for proper installation
• B. Certification indicating compliance with standards
• C. Identifies heat sources for temperature ratings
• D. Specifications for sprinkler coverage areas

Answer: (D)

Coverage criteria define the size and layout of the areas that a sprinkler head is expected to protect. It sets how large a protected area a single head can cover and how those areas are arranged to provide comprehensive protection across spaces. This concept directly guides where sprinklers are placed and how many are needed to meet the required protection in a low-rise residential system. The other items describe installation methods, product certification, or how temperature ratings are determined—things that relate to different aspects of the system, not the coverage area per head.
