The injection needle tube rigidity testing instrument is professionally used to measure the deflection value of the injection needle tube and the hard straight stainless steel needle tube for medical equipment.
Standard requirements, so the injection needle rigidity tester is also called the deflection tester
.
The detection principle of the injection needle tube rigidity detection instrument: apply the specified force to the center of the specified span of the needle tube supported at both ends, and measure the deflection value of the needle tube
.
The injection needle tube rigidity detection instrument can apply a force of up to 60N (accuracy is ±0.
01N) through the push rod.
The lower end of the push rod is formed by a wedge and a 60° angle with each other.
It consists of a cylindrical surface with a radius of curvature of 1mm and a push rod width of at least 5mm
.
The instrument is required to measure the displacement of the needle tube with a reading accuracy of 0.
01mm
.
Inspection process requirements: 1.
Place the needle tube on the injection needle tube rigidity testing instrument, and adjust the needle tube and the instrument according to the following requirements: ① Make the span equal to the value corresponding to the size of the needle tube to be tested in Table 2; ② Make the end surface of the strength push rod at Span center; ③ Keep the needle tube perpendicular to the two needle rack columns and the push rod, and at the same time make the center line of the needle tube coincide with the center line of the needle rack
.
2.
According to the force corresponding to the nominal specification of the needle tube in Table 2, apply a bending force to the needle tube through the push rod at a rate of 1mm/min
.
3.
Record the deflection of the needle tube at different force points, accurate to 0.
01mm
.
4.
The printing of the test report requires the test report to include the following aspects: ① the specification and description of the needle tube; ② the type of the tube wall of the needle tube: normal wall, thin wall, ultra-thin wall; ③ the measured deflection value (unit is mm, accurate to 0.
01mm) and the judgment result; ④The test date of the injection needle rigidity test standard requirements:
