fittings must show no deterioration for a Minimum
period of 5 years .
It does not require seacocks just to last 5 years or to be replaced after 5 years
Clearly a seacock showing no deterioration after 5 years does not need to be replaced at 5 years
Sadly the fact that iso standards are relatively expensive means few people outside boat
builders and suppliers actually read them, most people are relying on hearsay
The standard iso 9093 has been updated several times since its original release
