| 1、硬度试验的主要目的是测量ppr保温复合管的适用性，并通过对硬度的测量间接了解了它的力学性能，例如磨耗性能、拉伸性能、固化程度等; 1. The main purpose of hardness test is to measure the applicability of PPR insulation composite pipe, and through the measurement of hardness, the mechanical properties of PPR insulation composite pipe are indirectly understood, such as wear property, tensile property, curing degree, etc; 2、ppr保温复合管硬度值的大小是表示材料软硬程度的有条件性的定量反映，它本身不是一个单纯的确定的物理量，而是由材料的弹性、塑性、韧性等一系列力学性能组成的综合性指标。硬度值的大小不仅取决于该材料的本身，也取决于测量条件和测量方法; 2. The hardness value of PPR heat preservation composite pipe is a conditional quantitative reflection of the degree of hardness and softness of the material. It is not a simple physical quantity, but a comprehensive index composed of a series of mechanical properties such as elasticity, plasticity and toughness of the material. The hardness value depends not only on the material itself, but also on the measurement conditions and methods; 3、硬度检测在生产过程中对监控产品质量和完善工艺条件等方面有非常重要的作用; 3. Hardness testing plays an important role in monitoring product quality and improving process conditions in the production process; 4、硬度试验因其具有测量迅速、经济、简便且不破坏试样的特点，是工程材料应用极为普遍的方法，也是检测塑料性能比较容易的一种方法。 4. Hardness test is a very common method for engineering materials because of its rapid, economical, simple and nondestructive characteristics. It is also a relatively easy method for testing the properties of plastics. |
