ASTM D3786-2008A Test Method for Bursting Strength of Textile Fabrics – Diaphragm Bursting Strength Tester Method was revised in 2006 and 2008 to admit the use of the new pneumatic burst testers such as the SDL Atlas M229P PnuBurst. An error in the editing of the published method was found regarding the calculation of the diaphragm correction technique. See the proposed correction below.

Current:
11.3.2 Diaphragm Correction (Tare Pressure)—Using the same settings as employed to burst the specimen, record the pressure required to distend only the diaphragm to the same pressure and height as used to burst the specimen. Record this as the diaphragm correction (tare pressure).

Proposed change:
11.3.2 Diaphragm Correction (Tare Pressure)—Using the same settings as employed to burst the specimen, record the pressure required to distend only the diaphragm to the same height as
used to burst the specimen.
