State whether the following is true or false.
Cement standards specify test methods as well as performance requirements.

  • A.False
  • B.True only at large scales
  • C.False only at small scales
  • D.True

Answer: D

Correct answer: True

A standard specifies the method as tightly as the limit, because a requirement is meaningless without a defined way of testing it - the apparatus, the specimen, the curing, the loading rate and the tolerances all affect the number obtained. That is why a result is reported against the standard it was measured to, and why figures from different standards are not directly comparable.
