If you are following the PDF for a real-world test, follow this strict sequence:
Assessing changes in tensile strength, hardness, and elasticity. Technical Specifications Common Test Liquids
cubes for volume/mass changes and dumbbell shapes for tensile testing.
: Common liquids include standard reference oils (e.g., IRM 901, 902, 903), fuels like Gasoline No. 1 (specified in JIS K 2201 ), and various industrial chemicals Temperature and Time
JIS K 6258 is a Japanese industrial standard that specifies a method for determining the abrasion resistance of rubber materials. The standard is widely used in the rubber industry to evaluate the performance of rubber products, such as tires, belts, and hoses. The test method involves subjecting a rubber specimen to abrasion using a rotating drum abrader, and measuring the volume loss of the specimen.
