Before measurements are made, the sampleor test specimen shall be pre-conditioned under these atmospheric conditions for a timesufficient to allow the sample or the test specimen to reach stability. For taking samples inliquid or
44、 paste form, ISO 15528 shall be applied. For preparation of such samples for testing,ISO 1513 shall be applied.NOTE For definitions of terms for standard atmospheres, see ISO 558.
