(a) For the elongation data the first figure relates to wall thicknesses up to 40 mm: the second figure is for wall thicknesses over 40 mm and up to 63 mm; the third figure is for wall thicknesses over 63 mm and up to 100 mm.
(b) Impact tests are not required for specified thicknesses less than 6 mm.(c) The mean value of the three test pieces shall meet the requirements. One individual value may be below the specified value,
provided it is not less than 70% of that value.(d) Impact energy for the longitudunal direction and for wall thicknesses up to 40 mm, minimum impact energy in the transverse direction is 27J.(f) The elongation may also be determined in the transverse direction. In this case the minimum values to be achieved shall be those for the
longitudunal direction minus 2 points.
