ASTM D1876 胶粘剂的剥离强度测试-T型剥离
ASTM D1876 measures the comparative peel properties of adhesive bonds between flexible adherends by using a T-peel test. The test is referred to as a “T-peel” due to the shape the two flexible adherends form as they are pulled apart. Average peel strength for each specimen type and average, minimum, and maximum peeling loads for each individual specimen are the primary results of interest. Manufacturers use this standard for quality control in a wide range of industries as it is primarily intended for determining relative peel resistance between individual specimens or different types of adhesives. Direct comparison of different adhesives can only be made when specimen construction and test conditions are identical.
ASTM D1876 Test Setup
For peel tests, it is critical to use a high data acquisition rate to register all peaks and troughs in the data. Insufficient bandwidth may overlook important test events and lead to artificially low peel strength values. For this reason, we recommend an Instron 6800 series test frame, which enables a data capture rate of up to 5 kHz. The ASTM D1876 standard states that the maximum specimen load should fall between 15% and 85% of the maximum frame capacity, in most cases making a single column frame (68SC) with capacity of 5 kN or less ideal. If the adhesive requires a higher capacity system, Instron’s dual column table model frames are available up to 50 kN.

TIPS AND TRICKS
- When testing to ASTM D1876, the two adherends do not need to be the same material or thickness. However, if one adherend is more flexible than the other, attach the less flexible one to the moveable (top) grip.
- Bluehill Universal software comes with with one free application module upon purchase. Each module contains pre-configured test methods and supporting documentation to assist with testing to various standards. ASTM D1876 is included as part of the Adhesives module.
It is important to review ASTM D1876-08(2015)e1 in order to fully understand the test setup, procedure, and results requirements.

2712-05x Series Pneumatic Side Action Grips Data Sheet (50 N and 250 N)
The Instron 2712-05x Series Pneumatic Side-Action Grips offers a versatile gripping solution for a wide range of materials. Available in both 50 and 250 N options, the grip’s robust design is ideal for round (wires),fiber (mono-filaments), and flat specimens with or without shoulder.
2710 Series Screw Side Action Grips
Screw side‑action grips offer a straightforward and reliable way to secure test specimens across a wide range of applications. The dual‑acting design of the 2710‑100 series allows the jaw faces to adjust easily for different specimen thicknesses, keeping the tensile load path centered within the grip body. These grips support a variety of interchangeable jaw faces in multiple sizes and surface types, including smooth ground, rubber‑coated, serrated, line‑contact, and specialty coated options. A convenient snap‑on attachment system makes swapping jaw faces fast and hassle‑free, adding flexibility for diverse testing needs.
