bar test method, as outlined in
SAE J1637. However, the Oberst
bar test method has serious
limitations when it comes to the
lightweight materials used today.
" SAE J1637 came into the
picture in 1993, " Saha said. " But
SAE J1637 is usable for steel bars
only. "
The new recommended
practice, however, allows testing
on all sorts of materials:
aluminum, glass, composites,
and yes, even steel. Although
there are two other standards
with similar methodology to SAE
J3130-JIS G 0602 and ISO
16940-these applications are
limited to only testing steel and
glass bars, respectively. As the
AMC surveyed the resources
available to engineers for sound
package material
testing, they
Pranab Saha, Ph.D., P.E., is dedicated to developing unique, industry-critical
standards such as SAE J3130.
discovered a crucial need for a more-specific testing
procedure unique to the new materials being used for
the center bar.
" These test methods are not covered by ASTM, ISO,
or JIS standards, which are designed more for
architectural, commercial, and industrial applications, "
Saha said. " This is the main reason why the AMC
developed this standard. "
This gap in testing knowledge inspired the AMC's
multi-year effort, which brought together
representatives across industry to develop
the CenterPoint method.
Saha disclosed a personal passion for
creating distinct standards to cover
matters untouched by other
organizations. If, say, ISO or ASTM
has already published a standard on
a particular topic, he and the AMC
