BS EN 14477_{Packaging, Flexible Packaging material. The Determination of puncture hold. Test methods}

The Test summary

EN 14477 describes a test method of determining the puncture to hold of flexible packaging materials, o multilayer flexible packaging materials

The Test apparatus

The Force testing stand capable of fixed speeds of 1, 5, 10, 50 or 100 mm/min.

Compression will Load cell with fixtures to hold the penetration of the probe.

0.8 mm diameter penetration probe made of hardened steel with rounded tip of the radius of 0.4 mm.

The Sample holder to secure the Sample in place during the test.

Software to control stand movement, the capture force and below data, calculate, store and report the results

Preparation

A minimum of 10 specimens shall be seems, evenly spaced across indicates the biennial reel or sheet being *.

Samples should be conditioned at 23 + 2) (° C and (50 + 5) % RH for 48 hours before testing. The test shall be carried out at The same The conditions

The Test method

A pre - conditioned sample is clamped into the sample holder

The compression will loadcell reading is zeroed before The probe touches The sample.

The probe is driven through The sample at a constant speed of 1, 5, 10, 50, or 100 mm/min.

The peak force in N is recorded along with The elongation in mm.

For the determination of energy, the integral below the curve of the force and elongation shall be calculated.

The mean values and standard deviation of The values shall be calculated.

The test report shall include:

The reference to EN14477 standard
