JIS K 6854-4 Adhesives - Determination of Peel Strength of Assemblies - Part 4: Floating Roller Method

The JIS K 6854-4 standard, developed by the Japanese Industrial Standards organization (JIS), describes the floating roller method for measuring the peel resistance of high-strength adhesive joints between rigid adhesives and flexible adhesives under specified process and test conditions. The floating cylinder method provides a more constant value than other peel test methods. However, the flexible adhesive should not be expected to follow the roll surface.

Essentially, the JIS K 6854 standard consists of the following subsections under the main heading "Adhesives - Determination of the peel strength of assembled assemblies":

• JIS K 6854-1 Part 1: Peel with 90 degree mark
• JIS K 6854-2 Part 2: Peel with 180 degree mark
• JIS K 6854-3 Part 3: Adhesives - 180 degree marked peel test (T-peel test) for flexible-to-flexible bonded assemblies
• JIS K 6854-4 Part 4: Floating cylinder method

The standard in question is based on ISO 4578, published by the International Standards Institute (ISO) (ISO 4578 Adhesives - Determination of peel resistance of high-strength adhesive bonds - Floating cylinder method). This ISO standard describes a floating cylinder method for determining the peel resistance of high-strength adhesive bonds between a rigid adhesive and a flexible adhesive when tested under specific preparation and test conditions. For the purposes of this standard, peel resistance refers to the average force per unit test specimen width, measured along the bonding line, required to progressively separate two elements of a bonded test specimen under the specified test conditions. This force is expressed in kilonewtons per meter.

The principle of the floating roller method described in the JIS K 6854-4 standard is to measure the force required to peel the flexible adhesive from the rigid adhesive at an angle determined by the peel test piece fixture and use rollers to provide the flexible substrate.

Among the numerous test, measurement, analysis and evaluation studies that our company provides for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of JIS K 6854-4 standard, floating cylinder test services for the determination of the peel strength of adhesives and assembled assemblies are also available. gives.
