Pressure resistance test of carton tester

pressure resistance test of carton tester

Dongguan Haida instrument/

instrument: bf-w series computer servo carton compression testing machine, also known as carton compression testing machine, carton compression testing machine, strength testing machine, computer servo carton compression testing machine, carton compression testing machine, carton compression testing machine, Strength tester

the compressive capacity of corrugated box refers to the maximum pressure that the box can withstand when the two sides of the corrugated box are pressed at a uniform speed when the empty box is placed three dimensionally

n of compressive capacity

take three sample boxes whose boxes and surfaces shall not be damaged or have obvious bumps and stabs

the equipment for the pressure resistance test is the overall compression test machine for packaging containers

the main technical parameters of the overall compression test machine for packaging containers are:

measurement range: kn

load accuracy: 2%

pressing plate area: 1200mm 1200mm

from the analysis of the failure probability

Parallelism of lower plate: 2/1000

effective stroke of upper platen: 1000mm

standard speed 10mm/mm

stepless speed regulation/min

the test method for pressure resistance test is to close the three sample boxes in three dimensions, seal them up and down with sealing tape, place them in the middle of the lower platen of the compression tester, and start the machine to make the upper platen close to the empty box. Then start the pressurization standard speed until the box yields. Read the measured value

calculate the arithmetic mean of the test results

the anti pressure value of the tested corrugated box is calculated according to the following formula: CL k: clock input signal end

p=k g (h/h-1) 9.8

where: p:- anti pressure value, n

k:- deterioration coefficient (strength coefficient)

g:- gross weight of single package under the strong support of the state; Kg

h:- stacking height; M

h:- box height; Standardization is the realistic demand for standardized and refined urban management m

h/h:- rounding digits

according to the counting regulations in sn/t inspection procedures for corrugated boxes for transport packaging of export commodities, h/h is the speed digit. After the decimal point, whether it is large or small, it will be higher or lower

Provisions on deterioration coefficient in sn/t inspection procedures:

the storage period is less than 30 days, 30 days -100 days, and more than 100 days

the deterioration coefficient K 1.6 1.65 2

note: the deterioration coefficient (strength coefficient) k is determined according to the storage conditions of the goods packed in the carton

the qualification criteria of the anti pressure test is: when the anti pressure values of the three sample boxes are greater than the standard anti pressure values, the test is qualified. If one sample box is unqualified, the test is unqualified

VI. if all the performance inspection items are qualified, the performance inspection will be judged as qualified. If one item is unqualified, the performance inspection will be judged as unqualified
