Bolelele ba barrel ea ho tjhaja: 160±0.1 limilimithara

Bophara ba hlooho ea molamu oa piston: 9.475±0.005 limilimithara

Bolelele ba hlooho ea molamu oa piston: 6.350±0.100 limilimithara

2,Standard Test Force (Grade 8)

Kereiti ea 1: 0.325kg = (molamu oa piston + terei ea boima + letsoho la ho kenya mocheso + no. 1 boima ba 'mele)

= 3.187 N

Kereiti ya 2:1.200kg =(0.325+ No.2 0.875 boima)= 11.77N

Kereiti ya 3:2.160kg =(0.325+ No.3 1.835 boima)= 21.18N

Kereiti ya 4:3.800 kg=(0.325+ no.4 3.475 boima)= 37.26N

Kereiti 5:5.000 kg=(0.325+ no.5 4.675 boima)= 49.03N

Kereiti ya 6:10.000 kg=(0.325+ No.5 4.675 boima + No.6 5.000 boima)= 98.07N

Kereiti ya 7:12.000 kg=(0.325+ no.5 4.675 boima + No.6 5.000+ No.7 2.500 boima)= 122.58N

Kereiti ya 8:21.600 kg=(0.325+ nomoro 2 0.875 boima + Nomoro 3 1.835+ Nomoro 4

3.475+5 4.675+6 5.000+7 2.500+8 2.915 boima)= 211.82N

Phoso e amanang le boima ba 'mele≤0.5%.

4,Ho nepahala ha mocheso kamehla±0.5℃.

5,Phepelo ea motlakase:220V±10% 50Hz

6,Tikoloho ea mosebetsi: mocheso o teng ke 10℃-40℃;Mongobo o lekanyelitsoeng oa tikoloho ke 30% -80%;Ha ho na mokhoa o senyang o pota-potileng, ha ho na moea o matla;Ha ho na tšitiso le tšitiso e matla ea matla a khoheli ho potoloha.

7,Litekanyo tsa lisebelisoa:250×350×600=（L×W×H）

Sebopeho le molao-motheo oa ts'ebetso:
