An aging control system should be maintained to allow the hose to be used before it has reached its storage life.
The storage life is the time during which the hose can be expected to retain its full capabilities to provide its intended service.
Hose shall be stored in a manner that facilitates aging control and allows for FIFO (first in, first out), according to the date of manufacture of the hose or crimped hose.
If visual inspection should raise any doubt about the functionality of the hose (cracks in the cover, rust, etc.), a pressure test should be performed before use or, if not, the hose should be discarded.
HOSE SERVICE LIFE
ISO/TR 17165-2 states that the shelf life of hose as stored hose or as hose manufactured from 2 or more materials should not exceed 40 quarters (10 years) from the date of manufacture, if stored in accordance with ISO 2230.
According to DIN 20066:2002-10: The hose should be used before 4 years, according to its date of manufacture. The service life of a hose assembly, including any storage period, should not exceed 6 years; the storage period should not exceed 2 of these 6 years.
CORRECT STORAGE OF HOSES
Store in a cool, dry place (room temperature).
Avoid direct sunlight and humidity.
Do not store near high power electrical equipment.
