All of our rubber hoses go through rigorous testing before leaving our production facilities and in order to ensure consistent results and to document our findings we continually make investments to speed up and improve our testing facilities.
Get your own hoses tested for compliance
On request, we also test customer’s own hoses to ensure that they perform according to the official guidelines for specific applications. You may have stock of hoses, that require testing before coupling or assembly. Codan have the facilities for testing your hose in accordance with the relevant guidelines.

Our latest acquisition in equipment is a stereomicroscope which test the cleanliness by analysing the hoses for foreign particles. These tests are especially important with regards to fuel hoses and hoses which transport liquid in machines because contamination from foreign elements can damage engine parts and reduce performance.
Consistency in material ensures a longer life
Impurities in the compound can have an adverse effect and might therefore cause the hose to deteriorate prematurely. By ensuring a high consistency of materials used in the hoses, we ensure a long life and maximum performance throughout its use.
The tests are application dependent
Relevant to the application of the hose we analyse the quality of the vulcanization as well as performing pressure tests to make sure the hose can perform in the most extreme conditions.
Testing facilities
Our production facilities are TS16949 / ISO9001 and ISO14001 accredited and our products are designed to meet the strict requirements of OEM manufactures. To ensure that all of our products meet the stringent national and international standards, we continually carry out tests to ensure they meet the minimum requirement specified in each of the relevant norms.
Testing is carried out in accordance with international standards
Our in-house Test Centre perform industry accredited analysis of rubber compounds and the physical properties of rubber hoses.
We test the adhesion of the vulcanization
with a machine that measures the force
needed to pull the different hose layers apart.
With this method we can test the dynamic
behaviour of the hose for optimal performance.
The testing is carried out in accordance with
the following standards:
ISO 36
BS-903
DIN 53530
ASTM D 413
We determine the materials resistance to ageing by measuring the detoriation of the physical properties over time caused by oxidative and thermal ageing.
The testing is carried out in accordance with the following standards:
ISO 188
DIN 74310
SAE J 51
SAE J 30
The vulcanization of the hose is also tested with a bending test to ensure that there are no kinks and the hose doesn’t collapse when bent to a specified bending radius.
The testing is carried out in accordance with the following standards:
SAE J 1403
FMVSS 106
The hose is tested with hydraulic pressure to ensure the hose meet the specified requirements.
The testing is carried out in accordance with the following standards:
EN 1402
EN 139
SAE J 1401
SAE J 1402
SAE J 1403
We test the hose for foreign particles such as fibres and metal shrapnel.
The testing is carried out in accordance with the following standards:
ISO 16232
ISO 12584
SAE AS 4059F
ISO 4406:1999
The hose is frozen in a controlled environment to ensure that it can perform in cold conditions. After freezing it to the specified temperature, the hose is then bent and inspected it for signs of cracks.
The test is carried out in accordance
with the following standards:
DIN 74310
SAE J 30
SAE J 20
SAE J 1402
ISO 10619
The overall performance of the product is measured with a test of the hardness of the material.
The testing is carried out in accordance with the following standards:
DIN 53505
The purpose of the test is to expose the hose to a pre-determined amount of ozone to ensure that the hose is sufficiently weather resistant.
The testing is carried out in accordance with the following standards:
DIN 74310
DIN 53509
DUB 20024
BS 3212
ISO 1431
ISO 7326
SAE J 20
SAE 1402
EN 559
EN 27323
The test is performed by pouring a very accurate amount of liquid into a stainless container to which a sample of the hose is connected. After a set amount of time, the container is then weighed again to determine how much liquid has evaporated.
The testing is carried out in accordance with the following standards:
ISO 4080
ISO 7840
SAE J 2064
SAE J 30
DIN 4815
EN 559
EN 4080
Swelling or fluid resistance (also known as Change in volume) measures the deterioration of the material as is related to the change in volume of the fluid it is exposed to.
The testing is carried out in accordance with the following standards:
ASTM D380
DIN 4815
DIN 74310
SAE J 30
ISO 7840
The tensile test is performed in order to determine the strength of the material. By stretching a sample to breaking point, the stress-point, where it breaks, is the value that defines how strong the material is.
The testing is carried out in accordance with the following standards:
DIN 53504
SAE J 1402
SAE J 1401
BS 4667
BS 3212
EN 250
The hose is tested with vacuum to ensure that the hose can hold its shape and doesn’t collapse.
The testing is carried out in accordance with the following standards:
SAE J 1403
SAE J 30
SAE J 20
