Foreword
This Standard is drafted according to the rules given in the GB/T 1.1-2009.
This Standard replaced GB/T 5563-2006 “Rubber and plastics hoses and hose
assemblies - Hydrostatic testing”. Compared with GB/T 5563-2006, the main changes
of this Standard are as follows:
- ADD the terms and determination (refer to Chapter 3);
- REVISE the Chapter 4 (refer to Chapter 5; the Chapter 4 of 2006-edition);
- ADD “When a particular hose type or size needs longer measurement, it shall be
specified in the hose product standard.” (refer to 6.2);
- ADD “Note 1: use the term ‘maximum working pressure’ instead of the
deprecated term ‘design working pressure’. ” (refer to 8.1);
- REVISE the general procedure (refer to 8.2.1, 7.2.1 in 2006-edition);
- ADD “Apply 0.07MPa of pressure for approximately 5 min after completion of the
proof pressure test. The supporting surface upon which the hose/hose assembly
rests shall be flat and smooth enough to allow the hose/hose assembly to
expand or contract without restriction. Alternatively, the hose/hose assembly
may be supported on rollers, or suspended vertically. When a section of hose is
used as a test piece, it may also be placed in a test rig in a vertical position.”
(refer to 8.2.1.1);
- ADD “For hose assemblies, measure the distance between the contact faces of
the end fittings, or select the reference marks on the hose surface near the end
of the inserted part of the fitting.” (refer to 8.2.1.2);
- ADD “The change percentage in length will be positive (+) when increase length
and negative (−) when decrease length.” (refer to 8.2.2);
- DELETE “When the fittings are pull-out, any failures caused by leakage or burst
that is 25mm apart from the fittings or within the distance that equal to the hose
outer-diameter (maximum) shall not be considered as the real hose bursting.”
(refer to 8.3, 7.3 in 2006-edition);
- ADD Figure 3, the hydrostatic test procedure specified in this Standard (refer to
Figure 3).
This Standard uses translation method and equally adopts ISO 1402:2009 “Rubber
and plastics hoses and hose assemblies - Hydrostatic testing”.
The national documents that have the consistency and correspondence with
GB/T 5563-2013
international documents which are normative references in this Standard are as
follows:
- GB/T 2941-2006 Rubber - General procedures for preparing and conditioning
test pieces for physical test methods (ISO 23529:2004, IDT);
- GB/T 7528-2011 Rubber and plastics hoses and hose assemblies - Vocabulary
(ISO 8330:2007, IDT);
- GB/T 9574-2001 Rubber and plastics hoses and hose assemblies - Ratios of
proof and burst pressure to design working pressure (ISO 7751:1991, IDT);
- GB/T 9573-2003 Rubber and plastics hoses and hose assemblies - Methods of
measurement of dimension (ISO 4671:2007, IDT).
This Standard was proposed by China Petroleum and Chemical Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee on
Rubber and Products of Standardization Administration of China.
Drafting organizations of this Standard: Luohe Letong Rubber Co., Ltd., Guangzhou
Mingjun Balflex Rubber Co., Ltd., and Shenyang Rubber Research and Design Institute.
The main drafters of this Standard: Zhong Weijiang, Zhang Jingxiang, Wang Shuli,
Zhao Hongliang, and Zhang Tong.
The historical versions replaced by this Standard are as follows:

GB/T 5563-2013
Rubber and plastics hoses and hose assemblies
- Hydrostatic testing
1 Scope
This Standard specifies methods for the hydrostatic testing of rubber and plastics
hoses and hose assemblies, including methods for the determination of dimensional
stability.
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 standard.
ISO 4671 Rubber and plastics hoses and hose assemblies - Methods of
measurement of the dimensions of hoses and the length of hose assemblies
ISO 7751 Rubber and plastic hoses and hose assemblies - Ratios of proof and
burst pressure to design working pressure
ISO 8330 Rubber and plastics hoses and hose assemblies - Vocabulary
ISO 23529 Rubber - General procedures for preparing and conditioning test pieces
for physical test methods
3 Terms and definitions
The terms and definitions given in ISO 8330 apply to this document.
4 General requirements
Unless otherwise specified, all tests shall be carried out at standard temperature
(refer to ISO 23529).
5 Apparatus
5.1 Pressure pump
GB/T 5563-2013
t1 - keeping time of specified pressure;
t2 - measuring time of initial dimensions (length and diameter) under reference
pressure of 0.07 MPa;
t3 - waiting time specified under different pressures;
a - burst.
This complete test sequence (proof pressure - testing pressure - bursting pressure)
only applies to “type tests”. For routine tests, the “measuring sequence” after the proof
pressure is applicable only when the relevant hose product standard specifies.
Measure the initial length and diameter/circumference and place reference marks for
twisting measurement between points A and B. Measure the increase in the length,
diameter/circumference, twisting and warping directly before point C.

8.4 Leakage test
8.4.1 Test piece
The test pieces for the leakage test shall comprise unaged hose assemblies on which
the end fittings have been attached for not more than 30 days and not less than 1 day.
8.4.2 Procedure
Hydrostatic pressure specified in test assemblies shall be the 70% of minimum burst
pressure. Maintain this specified test pressure for 5 min ± 0.5 min and then reduce it
to zero. Re-apply the specified test pressure and maintain it for a further period of 5
min ± 0.5 min. This is considered as the destructive test and the test assemblies shall
be destroyed after test.
8.4.3 Criteria for failure
There shall be no evidence of leakage or failure.
Leakage at the end fitting, fitting blow-off or rupture of the hose adjacent to the fitting
shall be considered as failures in the performance of the assembly.
Note: Such failures do not necessarily demonstrate an inability of the hose to meet the
specified requirements with an alternative fitting.
