Testing principle
The test plate with glued specimens is hung vertically on the test stand, the weight of the specified weight is hung at the lower end, and the displacement of the sample after a certain period of time, or the time when the sample is completely detached, is used to represent the resistance to pull off of glued specimens.
The instrument complies with a number of national and international standards: GB 4851, ASTM D3654, JIS Z0237

Versatile Multi-Station TestingThe Tape Retentivity Tester is engineered to accommodate five specimens simultaneously, streamlining comparative adhesive tape evaluations. Each position features an independent digital timer, allowing operators to monitor and record retention time for each sample individually. This design enhances lab efficiency while maintaining precise, isolation testing.
Sturdy and Durable ConstructionManufactured with stainless steel fixtures and weights, the tester offers robust performance for repeated industrial or laboratory use. The anti-corrosion, powder-coated finish resists rust and chemical exposure, while the glossy surface ensures easy cleaning. Overload protection features and a stable base guarantee safety and operational reliability.
Precision Digital Control and Convenient OperationEquipped with digital timer control and LCD display, the device offers accurate measurement and instantaneous response upon tape failure. Manual placement ensures user oversight, and automatic timing stop improves consistency and reduces the risk of errors. Calibration is user-friendly, with manual reset and start for each specimen.
FAQ's of Tape Retentivity Tester:
Q: How does the Tape Retentivity Tester measure adhesive tape holding power?
A: This tester measures the holding power of adhesive tape by hanging a standardized 1000g weight from a tape specimen, then recording the duration until tape failure. Each specimen is monitored by its own digital timer which starts upon placement and stops automatically when the tape fails.
Q: What makes the tester suitable for laboratory and industrial settings?
A: With its stainless steel construction, anti-corrosive powder coating, overload protection, and easy-to-clean glossy finish, the tester is both robust and durable. Its multi-station, semi-automatic operation enables reliable, high-throughput testing in demanding environments.
Q: When should calibration be performed on this equipment?
A: Calibration is managed manually for each specimen before starting a test cycle. Operators simply reset and start the timer at the beginning of every new specimen test, ensuring accurate, reproducible results for every trial.
Q: Where should the Tape Retentivity Tester be installed for optimal performance?
A: The tester is designed for desktop mounting in controlled environments such as laboratories or quality control areas. It requires a standard AC 220V, 50Hz outlets and should be used at room temperature (232C) with 40-70% relative humidity for best accuracy.
Q: What is the process for conducting a tape retentivity test using this device?
A: After mounting up to five tape specimens (25 mm x 100 mm each) onto the fixtures, a 1000g weight is attached to each. Each timer is reset and started manually. The timers stop automatically when the tape fails, and results are read from the LCD display for each station.
Q: How can using this tester benefit adhesive manufacturers or quality control labs?
A: The tester enables simultaneous, repeatable, and precise evaluation of tape retention strength across multiple samples, improving workflow efficiency and data reliability. Its robust build and digital controls ensure consistent performance in routine production or research testing.
