Face mask tensile test machine maximum breaking strength tensile test solution

Medical protective supplies such as medical protective masks, medical protective clothing, medical gloves and other single-use medical supplies have a very good isolation of bacteria and viruses, as an important line of protection for medical personnel or the general public from bacterial and viral infections, the quality of the product itself is particularly important, its manufacturers need to carry out strict quality control, after a series of tests to pass the test requirements and carry out production.

Medical protective mask testing

Domestic mask production can mainly refer to the following testing standards: GB 2626-2006 respiratory protective equipment, GB 19083 medical protective masks, GB/T 32610 daily protective masks, YY 0469 medical surgical masks, YY/T 0969 single-use medical masks

Therefore, for the above standard testing requirements, QINSUN instruments provide the following testing instruments.

Breaking strength, static tension test items.

The standard "YY 0469 Medical Surgical Mask" stipulates that the breaking strength at the connection point between the mask band and the mask should be not less than 10N. To test this item, you can use the HT-101PT-05 series intelligent electronic tensile testing machine developed and produced by QINSUN Instruments, equipped with professional testing fixtures, to test the tensile strength and tensile breaking strength of the mask or mask band and the connection point.

The HT-101PT-05 is a professional instrument for testing the mechanical properties of various medical supplies; its ultra-high precision (0.5 grade) ensures the accuracy of the test; a variety of specifications of force sensors, as well as tensile and compression bi-directional test mode, can meet the user's various test requirements, and is ideal for pharmaceutical and medical industry enterprise customers to conduct product quality control testing.

Medical protective clothing testing

1、 Strength at break and elongation at break testing

The standard stipulates that the breaking strength of the key parts of the protective clothing material should be not less than 45N and the elongation at break should be not less than 15%. This indicator testing recommended the use of HT-140SC-05 intelligent electronic tensile testing machine, a tester integrated tensile, peeling, tearing and other seven independent testing procedures, extended version of the 1000mm long stroke can meet the test of large deformation rate materials, a variety of specifications of the force sensor and stepless speed regulation, for users of different test conditions to provide a convenient test.

2、 Protective clothing heat sealing tape peel strength testing

Protective clothing heat sealing tape is the key material for the production of protective clothing, from the base fabric and adhesive layer composite, pasted on the external seams of protective clothing to prevent the penetration of blood, body fluids, bacteria, dust particles. The HT-140SC-05 is a multi-functional testing machine that can test the tensile strength, breaking strength, elongation at break, peel strength and other items. The high precision sensor is fully capable of testing the peel strength of protective clothing tape.

 Medical glove testing

Domestic standards on medical gloves include: GB 10213-2006 medical rubber examination gloves for disposable use, YY∕T 0616 medical gloves for disposable use series standards. Combined with the requirements of the relevant standards, QINSUN instruments can provide the following testing instruments for relevant manufacturers or quality inspection units.

1, medical gloves tensile performance testing

GB 10213-2006 disposable medical rubber examination gloves" standard on the tensile performance testing in accordance with ISO 37 standards, from each glove sample cut three pieces, the choice of testing machine for testing. Customers can choose QINSUN instrument HT-140PT-05 medical supplies performance intelligent electronic tensile testing machine for medical gloves tensile performance testing; at the same time the series of tensile testing machine can also be used for medical gloves tearing force, tearing elongation index test, according to the standard requirements for specimen cutting, placed on the fixture of the tensile testing machine, select the correct parameter settings, click the test can Complete the automatic test.

2, medical gloves puncture resistance testing

The puncture resistance of medical gloves is directly related to the function of the glove in blocking bacteria or viruses, so the control of this indicator is very important. The ability of medical gloves to resist puncture is directly characterized by the force required to puncture the specimen, "YY∕T 0616.4-2018 Disposable medical gloves Part 4: Puncture resistance test method" standard, the configuration of the standard requirements of professional puncture device, clamped on the test machine, the puncture device should be under load conditions at a speed of 200mm / min uniform movement, the specimen puncture test. A total of 12 measurements of puncture resistance are performed and the average value is calculated. This test can be used QINSUN instrument HT-140PT-05 medical supplies intelligent electronic tensile testing machine to complete the test, the instrument has a level 1 high-precision sensor, equipped with professional puncture test device, easy to operate, automatic test.
