SF02-C blade sharpness tester is an efficient testing equipment for national inspection of product performance of manufacturers. It is based on "YY0174-2019 scalpel blade" and "YY0876-2013 linear cutting stapler and components", which are mainly used to determine the energy and physical characteristics of the sharpness of the blade.
The YY0174-2019 scalpel blade standard specifies the classification and identification, requirements, test methods, type inspection, labeling and instructions, packaging, transportation, storage and expiration date of scalpel blades. The standard applies to scalpel blades mounted on the handle of a scalpel for cutting soft tissues.

Test material b3
The test material was made of class I silk strands in accordance with YY0167-2005 uncoated 3-0 suture.
b.4 Test Methods.
b.4.1. The surface of the sample (blade) should be removed from the oil, and attention should be paid to maintaining the quality of the original product.
b.4.2 Test Steps:
The specimen (blade) is fixed to the grip;
Fix one end of the suture on a winding clip, add 100g weight to the other end of the suture to make the suture horizontal and fixed on the other winding clip, remove the weight, and prepare for testing;
The specimen moves vertically downward at a speed of no more than 10 mm s to cut the middle part of the suture; When the sutures are cut, the test values are recorded.
b.4.3. Press b. for each blade4.2. Test steps: Measure the front, middle and back three points of the cutting edge, and take the arithmetic average of the three test values as the test results.
