The testing instrument of YY/T 0962-2021 standard takes the pushing force tester as the core. It accurately measures the pushing force of gel during the injection process by simulating the actual injection scene to evaluate the injection performance, fluidity and uniformity of materials. The following is a detailed introduction to the testing instrument:

HDT-02 Pre filled Syringe Pushing Force Tester

1、 Core functions and testing principles

The core function of the pushing force tester is to simulate the actual injection process, pushing the syringe core rod at a constant speed to push the sample out through the needle. During this process, the instrument will record and generate a real-time pushing force curve, reflecting the dynamic changes in pushing force during the sample extrusion process. The magnitude of the pushing force directly determines the difficulty of extruding the sample, while the difference in pushing force can reveal whether the sample is unevenly dispersed or concentrated.

2、 Key testing parameters and standard requirements

• Pushing speedThe core testing speed is 0.05-500mm/min to adapt to the testing requirements of different products.

• Range of force measurementUsually ranging from 0 to 50N, the measurement accuracy can reach ± 0.5% FS, meeting the requirements of low resistance and high-precision detection.

• test environment: It shall be conducted at room temperature (23 ℃± 2 ℃) without obvious airflow interference to avoid environmental factors affecting the fluidity of gel and causing detection errors.

• Sample adaptationCompatible with mainstream medical beauty syringe specifications such as 1mL, 2mL, 3mL, and 5mL, supporting combination testing of injection needles with different inner diameters (25G~30G).

• standard requirementsIt is necessary to simultaneously detect and verify the three key parameters of pushing force, minimum pushing force, and average pushing force, and all indicators must be within the nominal value range of the product.
