Why TDM Cut Test Machine GT-KC28 Is Needed in PPE Testing
Why TDM Cut Test Machine GT-KC28 Is Needed in PPE Testing
In the personal protective equipment (PPE) testing system, cut resistance performance has always been a key indicator that cannot be ignored. Whether it is cut-resistant gloves, protective clothing, or industrial composite materials, they inevitably face cutting risks from sharp tools, metal edges, glass fragments, or high-speed moving parts in actual use environments.
To ensure that personal protective equipment performs at its best, effectiveness testing is required. In PPE testing, selecting an accurate, stable, and internationally compliant cutting test device is an important decision.
The application of GT-KC28 TDM Cut Test Machine provides strong assurance for the safety performance of PPE products, helping to reduce the incidence of industrial accidents and safeguard the life and health of workers.
In high-risk industries such as mechanical processing and metal smelting, cutting injuries are a common type of work-related injury, while qualified cut-resistant PPE products can effectively reduce the risk of injury. Through precise testing, GT-KC28 TDM 100 cut test machine ensures that the cut resistance performance of PPE products meets standard requirements, providing objective and reliable quality evidence for enterprises when purchasing PPE, and avoiding work-related accidents caused by the use of unqualified products.
Intelligent operation and data processing: The Cut Resistance Tester is equipped with a touch screen and supports Chinese and English interfaces. The operation is simple and intuitive, allowing users to get started quickly without professional technical personnel. At the same time, the equipment has comprehensive data storage, raw data query, and data export functions. Test reports can be exported via the USB interface, and with the built-in thermal printer, test data can be printed in real time.
High-precision control and stable transmission: The equipment adopts a high-quality branded servo motor system, high-precision ball screw, and rotary encoder to build a stable and reliable control and transmission system. At the same time, the vertical cutting force load range of the equipment is 0–100 N, the horizontal cutting force is stable at 25 N, and the force value error is controlled within ±5%. This high-precision force control capability can accurately capture the critical force at which the material is cut through, truly reflect the cut resistance performance of PPE materials, and ensure the repeatability and comparability of test data.
Flexible configuration options: The TDM 100 cut test machine provides a wide range of optional configurations. According to customer needs, it can be configured with American or Japanese blades to meet the special blade requirements of different test standards and different materials.
Compliance with international standards: The Cut Resistance Tester can meet the testing requirements of multiple international and national standards, including but not limited to ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, providing unified and reliable technical support for the certification of PPE products in different markets.
Personal protective equipment (PPE) testing can ensure that different types of PPE equipment are safe and reliable and can protect wearers as expected. The TDM Cut Test Machine has a wide range of applications and can be used for TDM grading tests (cutting force N) of shoe materials, gloves, protective clothing fabrics and other textiles, composite materials, rubber, and other materials.
In protective glove testing, the equipment can accurately test the cut resistance performance of gloves used in different industries such as glass processing, metal manufacturing, food processing, and chemical industries, providing a basis for the classification of glove protection levels and quality evaluation;
In protective clothing testing, it can evaluate the cut resistance performance of protective clothing fabrics used in mechanical processing, firefighting, emergency rescue, and other fields, ensuring that protective clothing can effectively resist cutting injuries during operations; in addition,
TDM Cut Test Machine can also be used for cut resistance testing of PPE products such as protective footwear materials, covering protective equipment for hands, torso, and limbs, and meeting PPE testing needs in different scenarios. Whether it is factory inspection by PPE manufacturers, compliance certification testing by third-party testing institutions, or material research and development testing by scientific research institutions, GT-KC28 TDM Cut Tester can provide stable and reliable testing solutions.
As global attention to production safety continues to increase, higher requirements are placed on the accuracy, intelligence, and standardization of PPE testing equipment.
As a professional device that is compatible with the TDM testing principle, comprehensively covers mainstream standards, and has continuous upgrade capabilities, GT-KC28 TDM Cut Test Machine can evaluate the cut resistance performance of PPE, protecting wearers from injury or other health-related risks associated with clothing and other items.
1. What is the difference between ISO 13997 and EN 388 cut tests?
ISO 13997: Uses a trapezoid-shaped blade and measures cut force (N) directly. Focuses on precise force data for material R&D.
EN 388: Uses a circular rotating blade and counts cut cycles (how many rotations to cut through the material). Used for glove product labeling per EU PPE regulations.
2. Why is the TDM method preferred for high cut-resistant gloves?
TDM (Trapezoidal DynaMometer) applies a straight, controlled cut force—better at simulating real-world sharp-object slashes. It avoids blade dulling issues of cyclic tests, giving more accurate results for high-performance materials (e.g., HPPE, Dyneema).
3. What materials can be tested with a TDM Cut Test Machine?
Most protective glove materials:
Synthetic fibers: HPPE, Dyneema, Kevlar, UHMWPE
Blended fabrics: Glass fiber + polymer composites
Coated materials: PU/ latex - coated cut - resistant fabrics
4. How does ASTM F2992 compare with ISO 13997?
Both use the TDM method (trapezoid blade, force measurement in N).
ASTM F2992: US standard, with specific blade calibration and sample preparation rules for North American markets.
ISO 13997: International standard, widely adopted globally for material performance benchmarking.
5. What does cut resistance level in EN 388 mean?
EN 388 rates cut resistance from A1 to A9 (higher = better). The level is determined by the number of blade rotations needed to cut the material:
A1: ≥10 cycles
A9: ≥200,000 cycles
6. What blade types are required for TDM Cut Test Machine?
Only trapezoid-shaped steel blades (per ISO 13997/ASTM F2992 specs). Blades must be sharpened to a standardized edge and calibrated before each test to ensure consistency.
