The TGA has increased the number of samples of PIP breast implants tested for shell integrity by measuring the tensile elongation of a further 7 samples to the original 8 samples that were tested in 2010. All tensile elongation results for the 15 samples now tested meet the requirements of the standard (ISO 14607:2007 Annex B Section 1.2) - the elongation at break of the shell specimen must exceed 450% compared to the original length of the specimen.
