    • PURPOSE: A rubber specimen for a breaking test and a breaking teat method using the same are provided to understand breakdown of elastomeric materials in consideration of real use condition. CONSTITUTION: A breaking teat method using a rubber specimen comprises following steps. A rubber specimen has fixed size and thickness. A hole which has diameter 0.5mm is formed at the center of a mark distance of the rubber specimen. A bore is formed on the inner diameter of the hole in a breaking direction and a direction at a right angle. Tension of the rubber specimen is tested by maintaining tension deformation rate below 200%. The rupture time of the rubber specimen is measured.
    • 目的:提供一种用于破碎试验的橡胶试样和使用该橡胶试样的破乳法,以便考虑到实际使用条件来了解弹性材料的分解。 构成:使用橡胶试样的破乳奶法包括以下步骤。 橡胶样品具有固定的尺寸和厚度。 在橡胶试样的标记距离的中央形成有直径为0.5mm的孔。 在破裂方向和直角方向上在孔的内径上形成孔。 通过将张力变形率保持在200%以下,测试橡胶试样的张力。 测量橡胶试样的断裂时间。
