Hose Abrasion Check
Instrument for the determination of the abrasion resistance of the outer cover of Rubber Hoses according to ISO EN 6945 and SAE J2006


Standards the instrument complies with:   
ISO 6945;   ISO 7840;   SAE J2006;    

Instrument characteristics 
The instrument has a solid aluminium and steel structure that ensures long duration and resistance to vibrations.
The abrading tool can be easily changed to replace emery paper. The instrument is provided with a safety protection door.
The digital speed controller ensures accurate regulation of the speed. The total number of cycles can be set according to the kind of hose being tested.
The fixing device for the hose has been specially designed to permit easy and rapid change of the hose. The standard sample holder provided enables testing to be carried out on standard hoses with 38 mm internal diameter.
Different sample holders of up to 60 mm external diameter can be prepared on request.

Description of the test 
A test hose with internal diameter 38 mm is mandel supported and rotates
at a constant speed of 80 ± 2 rpm. The rotating hose is subjected to a laterally moving abrasive surface (80 grit, coarse, AL203 emery cloth) parallel to the longitude axis of the hose.
The emery paper with 25 x 75 mm surface is firmly affixed to a hard surface, which moves back and forth 75 mm in each direction.
A constant force of 45 ± 5 N is applied to the abrasive surface. One test cycle equals 380 degrees rotation of the outside diameter and one back and forth movement of the abrasive surface.
After 1000 test cycles, each hose tested shall not have any rigid helix exposed.


Additional characteristics 
The instrument can be set to perform non-standard tests for research puposes:
- different abrading tools with non-standard shape are available and can be easily installed
- non-standard vertical force can be applied by replacing the weight on the abrading tool
- the rotation speed for the hose can be set to 60, 75 or 80 rpm
- the test can be performed with or without hose rotation




Standard Calibration service for an Abrasion Tester for Hoses 
The calibration is performed with reference to the requirements of ISO 6943 Standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of Test speed (Hz)
