The AWPA C Standards are no longer under development and have been replaced by AWPA Standards U1 and T1. U1 contains information for end users/specifiers, and T1 contains treating requirements for manufacturersApplies to each of the treating processes and to all species and types of material. If these requirements are to be otherwise modified to meet special conditions, complete detailed instructions shall be given.
The following requirements, as modified or
supplemented by other AWPA Standards, apply to each of
the treating processes and to all species and types of
material. If these requirements are to be otherwise
modified to meet special conditions, complete detailed
instructions shall be given.
Maximum time duration (total elapsed time of a
treating phase), maximum temperature, and maximum
pressure limits shall not be exceeded. Only those species
and preservatives listed in a commodity standard that have
previously been found suitable for use in this particular
application, or sufficient test information has been
submitted to warrant their inclusion.
A phase shall begin when a change in conditions
within the cylinder is initiated and shall end when either
new conditions are imposed or the cylinder is emptied of
preservative. For example, the period of steaming shall
begin when the temperature reaches 93 o C (200 o F) and end
when the steam is shut off in the cylinder and the cylinder
vented.
The minimum time duration, when stipulated for a
phase, shall be the period of time after the minimum
condition has been attained and until the end of that phase.
All dimensions referred to are nominal dimensions
for sawn four sides material.
