6.6.7.1.3 (02) List the number of a TYPE sprinkler allowed in a compartment, not the number of sprinklers. The commentary in the 02 handbook explains that in previous editions of 13R standard response was allowed, but now is QR. And this final line, "Additionally, when the exception for the standard response sprinklers was first accepted in 1988, listed quick response sprinklers were not as readily available as they are today".
