Annex A
(Supplement)
Transport package test method
A.1 Rain test
A.1.1 Test purpose
Spray water on the package at the specified time under normal temperature
conditions. Test the resistance of the package to rainwater.
A.1.2 Test equipment and site

The area covered by the rain shall be at least 50% larger than the bottom of the
package to be tested.
b. The rain shower device shall be able to spray 100±20 L/m2•h of water. Make
the water fall vertically on the top surface of the package 2m away from the
spray nozzle.
A.1.3 Test method
A.1.3.1 Rainfall calibration
a. The amount of rain must be calibrated before the rain test. Spray water fully
and evenly.
b. The amount of rain is calibrated by using several identical containers with an
opening area of 0.25~0.50m2 and a depth of 0.25~0.50m evenly placed on the
ground. Cover an area of at least 25% of the test land area. Then, open the
nozzle. Measure the time required for the first and last container to fill and
overflow. The time required for the first container shall not exceed the rate of
120 L/m2•h. The time required for the last container shall not be less than the
rate of 80 L/m2•h.
A.1.3.2 Test steps
a. Place the test package on the center of the spray surface of the test site.
Continuously spray for 1h as required.
