In the medical field, pre filled syringes have been widely used in various aspects such as vaccination, biopharmaceuticals, and clinical treatment due to their convenience, safety, and high efficiency. Its core advantage lies in the integration of drug storage and injection functions, which not only reduces the contact between medication and air, reduces the risk of secondary pollution, but also greatly improves the operational efficiency of medical staff. However, to ensure that pre filled syringes achieve the expected results in practical use, the critical step of pushing force testing cannot be ignored.The 2025 edition of the Chinese Pharmacopoeia has put forward higher requirements for the testing of the pushing force of pre filled syringes. The testing must strictly follow the YY/T 0962-2021 standard and evaluate the pushing force performance by simulating clinical use conditions to ensure medication safety and user experience.

To ensure the accuracy and consistency of the pushing force test, strict standards and specifications have been established both domestically and internationally. For example, YY/T 0962-2021 standard specifies the testing method for the pushing force of pre filled syringes, requiring a testing speed usually set at 30mm/min, but the specific value can be adjusted according to product characteristics and requirements. At the same time, the testing environment should be controlled at a temperature of 23 ± 2 ° C and a relative humidity of 50 ± 10% to reduce the influence of external factors on the results. In addition, the ISO 7886-1 standard developed by the International Organization for Standardization, as well as the Chinese national standard GB 15810-2019, have also put forward specific requirements for pushing force testing, such as using water as a medium and recording the maximum pushing force throughout the entire stroke.

To conduct a pushing force test, professional testing equipment such as a pre filled syringe pushing force tester is required. These types of devices typically have high-precision force sensors and displacement encoders, which can accurately capture subtle changes throughout the entire pushing process. During testing, fix the syringe in the fixture of the tester to ensure that the coaxiality of the piston rod and push rod meets the requirements. Then, start the tester and slowly push the plunger of the syringe at the predetermined speed, while recording the changes in force applied during the pushing process. The tester will automatically generate force displacement curves and calculate key indicators such as maximum pushing force and average pushing force.
