PREPARING CORRECTION SAMPLES
See the safety warnings in Chapter 2. Refer to Figure 18 on the
following page for a sample form for recording and calculating
data.
To prepare correction samples, follow the steps below:
1. Ensure that the oven is properly set up for ignition (see
Chapter 4) with an ACF of 0.0%. See page 6-8 for
instructions on changing the ACF, if necessary.
2. To ensure the accuracy of the ACF calculations, allow the
oven temperature to reach 540 C (default).
3. Prepare a correction sample that closely represents the
production mixture per ASTM D 6307, or local and state
requirements.
