Question 2589 Deck General

The correct answer is A) Metallic reinforcement. The requirements for oil transfer hoses do not include metallic reinforcement as a mandatory specification. The other requirements listed - a bursting pressure at least four times the sum of the relief valve setting and static head, a working pressure more than the sum of the relief valve setting and static head, and identification markings - are all valid requirements as per the relevant regulations. While metallic reinforcement may be a common or desirable feature, it is not an absolute requirement for oil transfer hoses. The other answer choices accurately reflect the regulatory requirements for oil transfer hoses.
