9 Test report
The test report shall include the following:
a) a reference to this document, i.e. ISO 3376:2020;
b) size of test piece used, standard or large (5.4);
c) the pre-load value if instrumentally applied;
d) the mean tensile strength, in MPa (or newtons per square millimetre), to the nearest 0,1 MPa, for the test pieces with the longer edge cut parallel to the backbone;
e) the mean tensile strength, in MPa (or newtons per square millimetre), to the nearest 0,1 MPa, for the test pieces with the longer edge cut perpendicular to the backbone;
f) the mean percentage elongation at maximum force to the nearest 1 %, for the test pieces with the longer edge cut parallel to the backbone;
g) the mean percentage elongation at maximum force to the nearest 1 %, for the test pieces with the longer edge cut perpendicular to the backbone;
h) the mean percentage elongation at a specified load to the nearest 1 %, for the test pieces with the longer edge cut parallel to the backbone; if required;
i) the mean percentage elongation at a specified load to the nearest 1 %, for the test pieces with the longer edge cut perpendicular to the backbone, if required;
j) the thickness of the sample, in millimetres, in accordance with ISO 2589;
k) any deviations from the method specified in this document;
l) full details for identification of the sample and any deviation from ISO 2418 with respect to sampling;
m) if required by the customer or in specifications, it is permitted to report the results described in n),
o) and p) instead of d) to i);
n) the average tensile strength, in MPa (or newtons per square millimetre), to the nearest 0,1 MPa [i.e. the arithmetic mean of d) and e)];
o) the average percentage elongation at maximum force to the nearest 1 % [i.e. the arithmetic mean of  f) and g)];
p) the average percentage elongation at a specified load to the nearest 1 % [i.e. the arithmetic mean of h) and i)], if required;
q) the standard atmosphere used for conditioning and testing, as given in ISO 2419;
r) the date of the test.ISO 3376 pdf download.
