Pipes shall be tested in accordance with 13.4 and the hydraulic test characteristics or the nondestructive test characteristics of the pipes shall be as follows. Which of the characteristics is to be tested shall be either in accordance with the designation by the purchaser or left to the discretion of the manufacturer.

a) Hydraulic test characteristics

The hydraulic test characteristics shall be as follows.

1) If a test pressure is specified by the purchaser, that pressure shall be applied as the minimum hydraulic test pressure, and the pipes shall withstand it without leakage. If the pressure value specified by the purchaser is greater than the value P calculated by formula (1) or 20 MPa, the test pressure to be applied shall be the subject of agreement between the purchaser and the manufacturer.

The purchaser may specify a pressure value lower or higher than the minimum hydraulic test pressure given in table 6, in which case, the specified value shall be in 0.5 MPa increments if lower than 10 MPa, and in 1 MPa increments if 10 MPa or higher. This applies also to the value calculated by formula (1), i.e. the obtained value shall be rounded to either 0.5 MPa or 1 MPa appropriately.

P= ~t ............................................................................. (1)

where, P: test pressure (MPa)

t: wall thickness of pipe (mm)

D: outside diameter of pipe (mm)

s: 60 % of the minimum proof stress value in table 4 (N/mm2

ISO 9329-4 6.2.1 Properties at room tem-

ISO 9330-6 perature: Tensile strength, proof stress, elongation, impact value, flattening resis-tance, drift expanding resistance are specified.

ISO 9329-4 9.9.3 Either a flattening test

ISO 9330-6 or a bend test or a ring tensile test shall be carried out.

- No specification.

ISO 9329-4 9.5 Either a hydraulic leak-

ISO 9330-6 tightness test or a non-destructive test shall be applied.



Deletion In JIS, impact values and drift expanding resistance are not speci-fied.

Addition In JIS, for welded pipes of 200A or over, the guide bend resistance of weld may be tested instead of the flattening resistance. In ISO, either a flattening test or a bend test or a ring tensile test, as selected by the manufacturer, is to be carried out.

Addition Not specified in ISO.

Alteration The hydraulic test pres-sure value specified in JIS is lower than that specified in ISO. Fur-ther, in JIS, the pur-chaser may specify the test pressure.


The impact values and drift expanding resis-tance relevant to pres-sure purpose pipes, which are not covered by this JIS, are deleted.

Correspondence to ISO can be made by perform-ing the flattening test. The bend test and the ring tensile test are not performed in Japan.

The specification is nec-essary for the guarantee of the creep strength of the product at elevated temperature; addition of this specification will be suggested to ISO.

The hydraulic test pres-sure can be altered as specified by the pur-chaser, and therefore no change is made in con-ventional JIS specifica-tion.
