"The current manufactured batch of ASF 71 hydraulic oil initially did not meet specifications. As a result, an investigation was conducted and performance testing was initiated to identify the root cause. Certain tests utilized in the investigation require testing periods of up to 3-4 weeks. The results of the investigation identified a nonconformance in one of the testing apparatus. The matter is currently near closure and full QC testing will be completed within 4 weeks on the batch. We apologize for any inconvenience that this has caused. Please understand that quality is taken very seriously to ensure the compliance and integrity of our products." - Chemtura (4-18-13)
