Overview

Template
The template is used to position the holes to be drilled for the
coupon over the fusion joint.
The template is attached to the pipe with two long wood
screws.
For smaller pipe, the template is attached using two long
U-bolts and wood screws.
There is an alignment mark on the template that is lined up
with the center of the fusion joint.
There are templates available for producing coupons with
different width relationships. The coupon will have a fusion
joint reduced area and a pipe material reduced area that
has a width that is a percentage of the fusion joint reduced
area. This gives an advantage to the fusion joint over the pipe
material.
Templates are available in 95%, 90%, and 85% width
relationships with others upon request. The In Field Tensile
Tester includes the 95% coupon template to test the fusion joint
reduced area for strength that is equal or exceeds the strength
of the pipe material ensuring a high performance fusion joint.
If you receive inconsistent results while performing the test, a
different percentage template can be used to better understand
the performance of the fusion joint.

Coupon
The coupon is the result of using the template and drilling and

the joint and the pipe.
