Room Temperature Tape Retention Tester (5 Stations)
This 62-second video introduces the DERUI DR-B301 five-station room-temperature tape retention (holding power) tester manufactured by Guangdong DERUI Testing Equipment Co., Ltd. It demonstrates the static-load test method: one-inch-wide adhesive tape strips are bonded to SUS#304 stainless-steel test plates, pressed with a 2 kg standard roller, and loaded with 1000 g weights so that each station automatically records how long the tape stays adhered before it detaches. The tester evaluates the holding power and lasting adhesion of pressure-sensitive tapes, labels and sticker products under room-temperature conditions.
What This Holding Power Video Shows
Test bench and stations
▸ Five-station configuration for parallel testing of up to five specimens
▸ Five timers with automatic retention of the elapsed test time
▸ Five SUS#304 stainless-steel test plates and five matching loading plates
Sample preparation and mounting
▸ One-inch-wide (25.4 mm) tape strips bonded to the cleaned test plate
▸ 2 kg standard roller presses each specimen at 300 mm/min over three return passes
▸ The loaded test plate is hung on the tester and the standard weight is attached
Loading and timing
▸ 1000 g ± 10 g weight per station, the weight including the loading plate
▸ When the tape detaches from the plate, the timer automatically retains the elapsed time
▸ The test evaluates the lasting adhesion and creep resistance of pressure-sensitive adhesives
How a Room-Temperature Retention Test Works
Step 1 - Prepare
Cut the adhesive tape into one-inch-wide (25.4 mm) strips of the required length.
Step 2 - Bond
Clean the SUS#304 test plate, bond the specimen over the required area, and press it with the 2000 g ± 50 g roller at 300 mm/min for three return passes. Apply only the mass of the roller, without additional force.
Step 3 - Load
Hang the test plate vertically on the tester and attach the standard weight (1000 g ± 10 g, including the loading plate) to apply a constant shear load.
Step 4 - Record
When the tape separates from the plate, the station timer automatically retains the elapsed time. Five specimens are tested and recorded independently at the same time.
DR-B301 Specifications
| Parameter | Specification | Selection note |
|---|---|---|
| Model | DR-B301 | Confirm the complete model designation on the quotation. |
| Test condition | Room temperature (ambient) | No heating function in this model; select a thermostatic tester if an elevated-temperature method is required. |

| Test plates | SUS#304 stainless steel, 5 pcs; thickness 1.5-2.0 mm, width 40-50 mm, length 60-125 mm | Plate dimensions are selected per the invoked standard. |
| Pressing roller | 2000 g ± 50 g | Rolled over the specimen at 300 mm/min, three return passes. |
| Weight (load) | 1000 g ± 10 g per station, including the loading plate | Confirm the load value required by the applicable standard. |
| Timer | Automatic retention of elapsed time; range up to 99999.9 h (or minutes, settable); 5 groups | Confirm the required units and resolution for your records. |
| External dimensions | Approx. 530 × 250 × 650 mm (L × W × H) | Confirm clearance and benchtop space. |
| Machine weight | Approx. 32 kg | - |
| Power supply | Required for the electronic timers - confirm the voltage and frequency with the quotation | This machine has no heating element. |
| Compliant standards | GB/T 4851, JIS Z0237, CNS 11888, PSTC-7 | Confirm the exact edition and procedure for your acceptance criteria. |
Where Room-Temperature Holding Power Testing Is Used
▸ Adhesive tape manufacturers - packaging, masking, double-sided, electrical and specialty tapes are checked for their ability to stay adhered under a sustained load.
▸ Label and sticker producers - self-adhesive labels, sticker and film products are checked for lasting adhesion so they do not peel or creep in service.
▸ Adhesive and PSA formulators - holding power and creep-resistance data support formulation development and batch-to-batch consistency.
▸ Quality inspection and incoming QC - holding power testing is a routine part of adhesive-product quality inspection in the adhesive industry.
Room-Temperature vs. Thermostatic Holding Power Testers
| Selection factor | Room-temperature tester (DR-B301) | Thermostatic (oven-type) tester |
|---|---|---|
| Test temperature | Ambient / room temperature | Controlled temperature, typically elevated |
| Typical use | Room-temperature holding power and lasting-adhesion tests | Heat-resistance and high-temperature shear behaviour of tapes and adhesives |
| Construction | Simple test stand with plates, weights and electronic timers; no heating system | Adds a heated cabinet with temperature control |
| Complexity and cost | Simpler structure, easier operation, more economical | Higher complexity and cost |
| Best choice depends on | Tape type, backing, adhesive system, the standard invoked and the temperature required by the acceptance test. Confirm the thermostatic model's specification separately if an elevated-temperature method applies. | |
Standards and Test-Plan Compatibility
The DR-B301 is designed for holding power (static-load) testing of pressure-sensitive adhesive tapes in accordance with GB/T 4851 (China), JIS Z0237 (Japan), CNS 11888 (Taiwan) and PSTC-7 (Pressure Sensitive Tape Council), as stated in the product datasheet. The same physical test - shear adhesion of pressure-sensitive tapes under a constant load - is also described by international procedures such as ASTM D3654 (room-temperature procedure) and ISO 29863; compatibility with any of these should be confirmed against the exact edition and procedure invoked.
Equipment capability alone does not prove compliance with every standard. Confirm the applicable edition and procedure, then verify performance with your actual tape, plate preparation, load and conditioning method.

Video Summary
This 62-second English-language video presents the DERUI DR-B301 five-station room-temperature tape retention tester. It demonstrates the weight-loading (static-load) test: one-inch-wide tape strips are bonded to SUS#304 stainless-steel test plates and pressed with a 2 kg standard roller at 300 mm/min over three return passes; 1000 g weights (including loading plates) apply a sustained load, and each station automatically retains the time until the tape falls off. The tester evaluates the holding power and lasting adhesion of pressure-sensitive adhesive tapes, labels and sticker products under room-temperature conditions.
