Side Impact Tube Beam for Passenger Car
1 Scope
1.1 This Standard specifies the basic parameters and dimensional tolerance, technical
requirements, test methods, inspection rules and marking, package, transportation and
storage requirements for the side impact beam for passenger car.
1.2 This Standard is applicable to the side impact tube beam for passenger car. The
side impact sheet or other-type beam for passenger car can also be implemented by
reference of this Standard.
2 Normative References
The following documents are essential to the application of this document. For the
dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) are applicable to this document.

GB/T 228 (all parts) Metallic Materials – Tensile Testing
JB/T 9204 Metallographic Examination of Induction Hardened Steel Parts
3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions apply.
3.1 Side impact beam for passenger car
The side impact beam for passenger car is the structure to strength the side door of
the passenger car; it can improve the ability of the side from invading when the side of
the passenger car is subjected to an external impact; reduce the intrusion amount for
the side of the car; meanwhile, it can absorb partial impact energy; reduce the injury
and danger to the occupants.
3.2 Side impact tube beam for passenger car
It indicates the component that consists of high-strength steel pipe welded with joint
the steel pipe shall not disconnect from the joint bracket.
6 Test Methods
6.1 Test conditions
The test temperature is 23°C±5°C.
6.2 Test items
6.2.1 Test method of surface quality
The inner and outer surfaces of the steel pipe are visually examined under light
6.2.2 Chemical composition
Perform the chemical composition analysis according to the relevant provisions of
GB/T 223.
6.2.3 Mechanical performance test Full-size longitudinal sample test
Insert the mating metal plug into the specimen specified in the standard Figure 2; so
that the tester jaws can hold the sample securely and the sample is required not to slip.
The plug shall not reach the test area where the elongation rate is measured. Figure 2
shown the shape of full-size longitudinal sample and metal plug, the position of plug in
the sample, as well as the position of sample in the tester. The test rate shall be carried
out in accordance with the provisions of GB/T 228.

6.2.5 Low-temperature impact test
Three samples shall be taken according to full-size pipe section of no less than 450mm
in length; maintain for 1h at -40°C environmental condition; then place onto the impact
testing device; finish the impact test within 20s. The support device of the testing
device has a radius of 17.5mm; span of 250mm, heavy hammer mass of 175kg, head
radius of 90mm; the heavy hammer is placed 1200mm above the steel pipe, it impacts
the middle of the steel pipe in a free-falling mode. The test schematic diagram is shown
in Figure 7.
When taking round steel pipe for impact test, the welding seam positions are impacted
at three positions of 0°, 90°, 180° (see Figure 5).
When taking elliptical steel pipe for impact test, the welding seam position is impacted
at the position of 90° (see Figure 6).

6.2.6 Metallurgical structure
If sample is taken in the middle of the full-size pipe section or taken at the position
specified in the part technical condition, there shall be no tempering during sampling
period. After the metallurgical sample is ground, use the alcohol solution containing
volume fraction of 2%~5% nitric acid to etch; then measure the microstructure at 400×.
6.2.7 Connection performance
The impact beam is firmly clamped on the material tester, the sample is required not
to slip. The tester shall be loaded at the speed no more than 5mm/min till reach the
Unit: mm
d) When there is big difference between the exit-factory inspection and the previous
type inspection;
e) When it is for normal production, it shall be performed once a year;
f) When the national quality supervision agency proposes the requirements for
carrying out type inspection. Random sampling
The steel pipes produced on the same production site, with the same raw material, the
same equipment and process shall be regarded as on batch. The products for type
inspection shall be randomly taken from the same batch of products that pass the exit-
factory inspection; the number of sampling shall be no less than 13; while the random
sampling base shall be no less than 70. The specific random sampling method shall
be determined by the manufacturer and host manufacturer. The type inspection items include all contents listed in Clause 6. Qualification judgment
When all type inspection items meet the requirements, it shall be judged as qualified.
If there are unqualified technical indicators in the inspection items, it is allowed to
double the random sampling quantity for re-inspection (or agreement between the
manufacture and host manufacturer) from the same batch; the re-inspection results
shall prevail. If the re-inspection result is qualified, then such batch of products is
qualified; otherwise, it is judged unqualified.
8 Marking, Package, Transportation and Storage
8.1 General requirements
8.1.1 The side impact tube beam for passenger car shall be packed neatly and bundled
firmly, which shall ensure that products are not loose, moisture, deformed, or damaged
during the normal transporting and storing period. The word of the marking shall be
8.1.2 The packaging materials shall comply with the relevant laws and regulations.
8.2 Marking
The side impact tube beam for passenger car shall have the following signs:
a) The name of the manufacturer and the registered trademark;
b) Product name and code, manufacture date or production batch number.
