Introduction

In the Danish DanDas standards, we have a calculated scoring value for the pipe called the Fysisk Indeks (Physical Index).

...

The calculations are the same for both standards.

...

The Lookup Table

These are the lookup values for the scores that are used to calculate the Fysisk Indeks. The values are the same for DanDas 2.5 and 2.6 Except for the two values at the bottom that are highlighted in red. These values are only used in DanDas 2.5 and are not used in DanDas 2.6.

...

The table is split by code groups in each line and by class in the columns 0-4.

The Where observation codes have more than 2 characters, they begin with the two-letter code group, then a class number and then some other characterisations to describe the code, so the class number is always the 3rd character in the code string and the code group is always the first 2 characters in the code string.

...

The result of this is that the VA (water level) is defined in the inspection from the beginning to the end.

...

The Calculations

The calculations of S and F look like this:
