Pressure-sensitive adhesive tapes and sheets are materials that adhere to a surface by applying pressure, without the need for heat, solvent, or other activation. They are widely used for packaging, sealing, labeling, masking, bonding, protecting, and other purposes. They can be made of various materials, such as paper, plastic, metal, rubber, or cloth, and have different types of adhesives, such as acrylic, silicone, rubber, or resin.
JIS Z 0237 provides a uniform and reliable way to evaluate the quality and performance of pressure-sensitive adhesive tapes and sheets. It covers various physical properties and characteristics of the materials, such as thickness, width, length, tensile strength, elongation, adhesion, peel strength, shear strength, tackiness, heat resistance, moisture resistance, aging resistance, and more.
Scope and application of JIS Z 0237
JIS Z 0237 applies to all kinds of pressure-sensitive adhesive tapes and sheets that are used for industrial or general purposes. It does not apply to medical or pharmaceutical products, electrical or electronic products, or products that are subject to special regulations or standards.

The test specimen should be conditioned and prepared according to the following steps:
The test specimen should be cut from the pressure-sensitive adhesive tape or sheet with a suitable cutting device, such as a knife, scissors, or die cutter.
The test specimen should have a smooth and clean surface, free of wrinkles, folds, bubbles, or defects.
The test specimen should be stored in a standard atmosphere of 23 2C and 50 5% relative humidity for at least 24 hours before testing.
The test specimen should be applied to a standard substrate, such as glass, steel, or paper, with a uniform pressure of 10 2 N/cm for 10 1 seconds.
The test specimen should be left on the standard substrate for at least 20 minutes before testing.
Expression of test results
The test results should be expressed according to the following rules:
The test results should be reported as the arithmetic mean of at least five measurements, unless otherwise specified.
The test results should be rounded off to the nearest unit of measurement, unless otherwise specified.
The test results should be accompanied by the relevant information, such as the type and size of the test specimen, the type and condition of the standard substrate, the test method and apparatus used, and any deviations from the standard.
Acceleration procedure
The acceleration procedure is a method to evaluate the change in performance of pressure-sensitive adhesive tapes and sheets after exposure to elevated temperature or humidity. It can be used to simulate the aging or deterioration of the products in a shorter time.
