特殊測試項目： 

A. 彈性系數即彈性楊氏模量定義：同相位的法向應力分量與法向應變之比。為測定材料剛性之系數，其值越高，材料越強韌。
B.比例限：荷重在一定范圍內與伸長可以維持成正比之關系，其醉大應力即為比極限。
C.彈性限：為材料所能承受而不呈永久變形之醉大應力。
D.彈性變形：除去荷重后，材料的變形完全消失。
E.永久變形：除去荷重后，材料仍殘留變形。
F.屈服點：材料拉伸時，變形增快而應力不變，此點即為屈服點。屈服點分為上下屈服點，一般以上屈服點作為屈服點。屈服(yield)：荷重超過比例限與伸長不再成正比，荷重會突降，然后在一段時間內，上下起伏，伸長發生較大變化，這種現象叫作屈服。
G.屈服強度：拉伸時，永久伸長率達到某一規定值之荷重，除以平行部原斷面積，所得之商。
H.彈簧K值：與變形同相位的作用力分量與形變之比。
I.有效彈性和滯后損失：
在拉力試驗機上，以一定的速度將試樣拉伸到一定的伸長率或拉伸到規定的負荷時，測定試樣收縮時恢復的功和伸張時消耗的功之比的百分數，即為有效彈性；測定試樣伸長、收縮時所損失的能與伸長時所消耗的功之比的百分數，即為滯后損失。

廣泛應用于電線電纜、紡織物、防水材料、無紡布、安全帶、橡膠、塑料、薄膜、鋼絲繩、鋼筋、金屬絲、金屬箔、金屬板材和金屬棒絲等金屬材料和非金屬材料及零部件產品進行拉伸、壓縮、彎曲、撕裂、90?剝離、180?剝離、剪切、粘合力、拔出力、延伸伸長率等試驗，以及一些產品的特殊力學性能試驗。

5.1.1 General Requirements

5.1.1.1 The testing machine frame should have sufficient rigidity and testing space, and should be able to easily conduct various tests. It should also be convenient for the loading and unloading of specimens, specimen fixtures, and testing machine accessories, as well as the installation and use of standard force measuring instruments.

5.1.1.2 The testing machine should be stable during the application and removal of force, without any impact or vibration phenomena.

5.1.2 Tensile test clamping device

5.3.2.1 During the process of applying force and at any position, the center lines of the upper and lower clamps and specimen jaws of the specimen clamping device for tensile testing should be coaxial with the force axis of the testing machine, and their coaxiality should be:

——For testing machines with a maximum capacity of no more than 5kN, the diameter should not exceed 2mm/500mm;

——For testing machines with a maximum capacity greater than 5kN, they should comply with the provisions of Table 4.

5.3.2.2 The clamp should ensure reliable clamping, and the specimen should be uniformly clamped along the entire length of the clamping part, and should be able to apply the maximum force of the testing machine to the specimen. There should be no relative slip between the specimen and the clamp under applied force or during the testing process.

5.3.2.3 After unloading the force or conducting a tensile test on the specimen, all parts of the clamp should be undamaged.

5.3.2.4 The jaws should have interchangeability.

Special testing items:

A. The elastic coefficient, also known as the Young's modulus of elasticity, is defined as the ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

B. Proportional limit: The load can maintain a proportional relationship with elongation within a certain range, and its maximum stress is the specific limit.

C. Elastic limit: The maximum stress that a material can withstand without permanent deformation.

D. Elastic deformation: After removing the load, the deformation of the material completely disappears.

E. Permanent deformation: After removing the load, the material still retains deformation.

F. Yield point: When a material is stretched, the deformation increases while the stress remains constant, and this point is called the yield point. The yield point is divided into upper and lower yield points, and generally the upper yield point is taken as the yield point. Yield: When the load exceeds the proportional limit and elongation is no longer proportional, the load will suddenly drop, and then fluctuate up and down over a period of time, causing significant changes in elongation. This phenomenon is called yield.

G. Yield strength: The quotient obtained by dividing the load at which the permanent elongation reaches a specified value during stretching by the original cross-sectional area of the parallel part.

H. Spring K value: the ratio of the force component in phase with the deformation to the deformation.

I. Effective elasticity and hysteresis loss:

On a tensile testing machine, when the specimen is stretched at a certain speed to a certain elongation or to a specified load, the percentage of the recovered work during shrinkage and the consumed work during stretching is measured as the effective elasticity; The percentage of the energy lost during the elongation and contraction of a sample compared to the work consumed during elongation is called hysteresis loss.

Scope of application:

Widely used in tensile, compressive, bending, tearing, 90 ? peeling, 180 ? peeling, shear, adhesion, pull-out force, elongation at extension and other tests for metal and non-metal materials and component products such as wires and cables, textiles, waterproof materials, non-woven fabrics, seat belts, rubber, plastic, film, steel wire ropes, steel bars, metal wires, metal foils, metal sheets and metal rods, as well as special mechanical performance tests for some products.
