Which criteria should not be considered in the selection of sprinklers to be tested?

The selection of sprinklers for testing should consider various factors to ensure effective maintenance and reliability of the system. While ease of access is an important operational consideration, it should not be a primary criterion in the initial selection of which sprinklers to test.

The age of the sprinklers is significant because older sprinklers may have a higher likelihood of having degraded performance due to factors like corrosion or wear. The material of construction impacts the durability and efficacy of the sprinklers under different conditions, particularly in environments that may be corrosive or subject to extreme temperatures. The type of sprinkler system in place informs the testing procedures and the performance requirements; different systems will have different operational expectations.

In contrast, ease of access, while relevant for practical inspection and testing execution, does not affect the fundamental criteria related to the condition and functionality of the sprinklers themselves. Therefore, it should not weigh as heavily in the decision-making process regarding which sprinklers are selected for testing.
