identical package filled with water must 
show that the maximum temperature 
measured inside the packages during test-
ing does not differ by more than 200 

°

mit the slow escape of gas (

i.e. 

not more 

than 0.1 mL/hour per 30 mL inner pack-

ganic peroxide type E, liquid or UN 3109 Or-
ganic peroxide type F, liquid may be fitted 
with a vent consisting of hydrophobic 
membrane, provided: 

(1) Each inner packaging contains not 

more than 70 mL; 

(2) The inner packaging is designed so that 

the vent is not immersed in liquid in any 
orientation; 

(3) Each inner packaging is enclosed in an 

intermediate rigid plastic packaging 
with a small opening to permit release of 
gas and contains a buffer that neutral-
izes the contents of the inner packaging 
in the event of leakage; 

(4) Intermediate packagings are packed in 

a fiberboard box (4G) outer packaging; 

(5) Each outer packaging contains not 

more than 1.4 L of liquid; and 

(6) The rate of oxygen release from the 

outer packaging does not exceed 15 mL 
per hour. 

b. Such packages must be transported on 

cargo aircraft only. The requirements of 
§§ 173.24(g)(1) and 173.27(c) do not apply.
