This standard specifies the oil-immersed tensile strength, oil absorption rate, oil-immersed thickening rate, oil-immersed appearance change, oil-immersed softness, oil-tightness, and corrosion test methods for oil-resistant asbestos rubber sheets. This standard is mainly applicable to the oil-resistant asbestos rubber sheet specified in GB/T 539. Other oil-resistant asbestos rubber sheets can also be used as a reference.
