如果没有指定摩擦系数这个参数指引,消费者很难确保产品是否适合自己的要求。汽车刹车片产品的包装上,要求标有指定摩擦系数。美国汽车工程师协会标准(SAE)对刹车片的摩擦系数主要分为四个等级:EE级(0.25-0.35适用于欧美车系,刹车片比较大,摩擦系数比较低),FF级(0.35-0.45国际标准摩擦系数),GG级
If you do not specify the friction coefficient of this parameter guidelines, it is difficult for consumers to ensure that the product is suitable for their own requirements. Brake pads on the product packaging, the required standard marked with the friction coefficient. American Society of Automotive Engineers standard (SAE) on the friction coefficient of the brake pads are mainly divided into four levels: EE level (0.25-0.35 applicable to Europe and the United States car, brake pads relatively large, the friction coefficient is relatively low), FF grade (0.35-0.45 International standard friction coefficient), GG level
