Packaging Drop Test Method

- Nov 07, 2019-

5.3.1. Why do you do the drop box test?

5.3.2.1. In the process of transportation, workers throwing boxes from one place to another is the main cause of product damage.

5.3.2.2. Collision often occurs when packaging is handled.

5.3.2. Crash-test shall conform to the requirements of ASTM D5276, which describes instruments

5.3.3. D5276 accurately introduces the height of box drop;Accurate control of drop box and drop concrete/stone/steel plate platform.

5.3.3.1. Throwing platform

Specific throwing platform is generally steel plate, if the surface uneven, it is recommended to use filler or thin mud fill.Sometimes a large reinforced concrete platform can be used to meet the requirements, with a throwing platform of at least 13MM

5.3.3.2 free fall test sequence

 

●ISTA 1A(150LBS or 150LB below 1 Angle, three sides, six sides

(bottom * weak corner, if not sure, choose the bottom corner of the seam edge)

●ISTA 1B(over 150LBS) 6 sides

●FEDEX(150LBS or 150LB) 1 corner, 3 sides, 6 sides

●NMFTA RULE 181(A procedure) 1 Angle, 3 sides and 6 sides

●NMFTA RULE 181(B) 1 Angle, 3 sides and 6 sides

5.3.4. Edge drop - the opposite side of the finger

5.3.5. It broke surface

5.3.6. Wrestling

5.3.7. Height of box drop

5.4. Load test

5.4.1. Why do weight tests?

5.4.1.1. The main reason for damage of products stored in the warehouse or box is load.Products pile up and squeeze each other to create a load.The higher the heap, the heavier the load.

5.4.1.2. Simulate load to check package products

5.4.2. Ista-1c loading test

Computational load

Press and hold for an hour

Weight (pound force) =300+ product weight +3× (length + width)

Weight 750 pounds

5.4.3.NMFTA RULE 181 load test

Calculate the load

Weight (pound force) =10PCS× (108-h) × (L×W) ×DF/1728 cubic inches/cubic inches -DF=design fact5(DF= parameter 5)

Weight 750 pounds

 

£1B and the modified ISTA do not require a weight-bearing test

5.4.5. Record (check and record the obvious damage on the packaged products)
