Intent 1:
To limit the probability that:
- inappropriate tools will be used, which could lead to
inadequate joint strength,
- excessively large branch sizes will be used, which could
lead to excessive weakening of run tubes, or
- the strength of brazing material will be inadequate,
which could lead to inadequate joint strength.
This is to limit the probability
of joint failure, which could lead to leakage, which could lead to
damage to the building or facility.
