Foreword
Instead of the standard YS/T 336-1994 "copper, nickel and alloy pipe and bar fracture test."
Compared with this standard YS/T 336-1994, the main changes are as follows.
Content --- the addition of foreword, scope, methods, principles, inspection reports;
--- "4 Sample Preparation" added "to break the fracture should be kept clean and not allowed to damage or contamination" and so on;
--- In "5 test methods" provides that "the fracture should be visual inspection, visual identification is difficult, can be 10 times the magnifying glass inspection
Inspection, and defect size determination. "
This standard by the National Standardization Technical Committee of non-ferrous metals and centralized.
The standard by Chinalco Luoyang Copper Co., Ltd. is responsible for drafting.
The main drafters of this standard. Zhu Yingli, Menghui Juan, Zhao million to spend, steady Guo Hui, Cao Li, Wen positive thunderstorm.
This standard replaces the standards previously issued as follows.
--- YS/T 336-1994, YB732-1971.
Copper, nickel and alloy pipe and bar fracture test
1 Scope
This standard specifies the principle of the method of copper, nickel and alloy pipe and bar fracture test methods, general requirements, sample preparation, test side
Law, the results of determination, inspection reports.
This standard applies to copper, nickel and alloy pipe, rod fracture test. According to fracture test to determine the quality of the internal tube rod
Happening.
2 principle of the method
The article by manual or mechanical break with visual inspection of the fracture.
3 Requirements
3.1 fracture test should end product (extruded products against pressure than the end) were.
3.2 fracture test shall be the number of the corresponding standard product requirements or by both parties through consultation.
4 Sample Preparation
Broken pipe and bar fracture width 4.1 shall comply with the requirements in Table 1 and Table 2.
Table 1 pipe fracture width
Pipe diameter /
mm
Fracture width /
mm
Sawing method
≤50 ≥ 40% of the pipe diameter
> 50 ≥20
Both sides remain central sawing
Note 1. ≤25mm inner diameter of the pipe, saw both sides, the fracture width may not be less than 15mm.
Note 2. Lead brass tubing allows side cutting, the fracture width of not less than 50% of the pipe diameter.
Table 2 bars break width
Bar diameter /
mm
Fracture width /
mm
Sawing method
< 16 ≥5 (or ≥2/3 diameter) saw both sides
≥16 ~ 40
50% ≥ bar diameter side sawing
≥10 sides remain central sawing
> 40 ≥10 saw both sides remain central
