HIAC codes
Table 10 shows the HIAC 4406 codes that are based on ISO 4406.
To change HIAC codes to ISO codes, delete all of the digits to the right of the decimal point. Do not
change the value either up or down. For example, a HIAC code readout of 7.2 is equivalent to an ISO
code of 7. A HIAC code of 7.8 is also equivalent to an ISO code of 7.
