I need to perform a tensile test on a 30 micron thick electrospun polymer film, and fabrication limits the maximum length of a specimen to 80 mm.
Similar publications have used the ASTM D638 standard, which requires the specimen to be at least 1 mm thick. Others have just used simple rectangular strips with custom dimensions without mentioning any standard.
For publications on electrospun polymers, is it acceptable to not follow a specific tensile testing standard ? If not, which one would be applicable in my case ?
For controlling the firmness of the sample, you must use hard paper or plastic film and grip it with aluminum foil or other laminates. please follow the link for detailed procedure. http://electrospintech.com/SOP-ES2002.html#.XGixeOgzbIV
I haven't gone over various testing standards, however, the general rule is to follow the applicable and appropriate standard (ASTM, etc.). Thin films could have different characteristic properties than their thicker counterparts. Thus, in the absence of an accepted standard, it would be safer to employ a testing standard nearest to the former.
