In the case of large amount of foam liquid, it is necessary to send it to a qualified testing unit for testing. The foam solution should be checked under one of the following conditions: The design dosage of 6% low-expansion foam solution is greater than or equal to 7.0t. The design dosage of 3% type low-expansion foam solution is greater than or equal to 3.5T. The lower limit reserve of foaming fluid in 6% protein type is greater than or equal to 2.5t. The lower limit reserve amount of multiple foam liquid in 6% synforming is greater than or equal to 2.0t. The lower limit reserve of high-expansion foam liquid is greater than or equal to 1.0T.
