5 Testing of mechanical splices 机械连接测试

5.1 General 总论

All tests shall be carried out on mechanical splices assembled in the same manner as they are prepared for normal use, see 5.2.

对于需要进行测试的机械连接，其测试时的安装方式必须与其在实际应用中的安装方式一致。

The installation instruction documents for the coupler shall be made available to the testing laboratory.

必须将接头安装指南提供给测试实验室。

A reference bar from the same heat shall be tested to determine its actual mechanical properties.

必须对取自同一热处理批次的参考钢筋进行检测，确定其实际机械性能。

The test methods covered by this part of ISO 15835 are: ISO 15835包含以下测试项目:

a) tensile test; 拉伸测试

b) slip test; 滑移测试

c) high cycle fatigue test; 高频疲劳测试

d) low cycle fatigue tests. 低频疲劳测试

The performance of mechanical splices may be dependent on the rib geometry of the steel reinforcing bar. 机械连接的性能可能取决于钢筋肋的几何形状。

The specified rib geometry of the test bar shall be provided by the supplier and recorded with the test results.

供应方必须提供钢筋肋的标准几何形状，实验室记录在实验测试结果中。

Foreword

This document (EN 10216-3:2002) has been prepared by Technical Committee EC/TC 29, "Steel tubes and fittings for steel tubes", the secretariat of which is held by UNI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.

Other Parts of EN 10216 are:

Another European Standard series covering tubes for pressure purposes is:

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

ISO 657-1 : 1988 (E)

Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
