The correct answer is B. Lubrication sampling . The cleanliness of newly delivered oil cannot be assumed based on supplier reputation, brand, container appearance, or purchase specification alone. New oil is not automatically clean oil. It may contain particulate contamination, water, additive issues, or handling contamination introduced during manufacturing, transfer, storage, delivery, or dispensing. The first reliable way to confirm cleanliness is to take a representative sample and analyze it against the required cleanliness target, such as an ISO 4406 cleanliness code for particulate contamination. Lubrication storage is important, but it becomes more relevant after delivery acceptance because poor storage can degrade or contaminate lubricant condition. Lubrication brand is not a valid confirmation method; even reputable brands can be contaminated if handling controls are weak. In CRL Asset Condition Management, lubrication is treated as a condition-control discipline. Proper sampling validates whether the lubricant is suitable for service before it is introduced into equipment. This prevents avoidable bearing, hydraulic, gear, and servo-system failures caused by contaminated lubricant.
