They provide customers with technically advanced materials designed for superior application performance. Furthermore, Berkshire focuses on total solutions that consistently minimize the risk of product and process contamination.

Unwavering Commitment to Quality

Berkshire Corporation was the first US manufacturer of contamination control products to receive ISO 9001 certification. This demonstrates their ongoing commitment to quality. This rigorous process ensures Berkshire customers use the world’s cleanest, most consistent products—products truly “Engineered Clean.”

• Process Management Plans: They implement robust plans for managing all processes.
• Raw Material Specifications: Strict specifications guide all raw material selection.
• Supplier & Incoming Inspection: They combine supplier testing with thorough incoming inspection.

Precision Through Statistical Process Control (SPC)

To ensure processes operate within appropriate limits, Berkshire Corporation employs Statistical Process Control (SPC). They use statistical techniques to monitor the quality of their processes and products, thereby delivering the highest-quality and most consistent products possible.

Their statistically developed control limits provide critical parameters for real-time analysis, monitoring, and alarms regarding critical process inputs. An in-house metrology enables the measurement and testing of critical process parameters and product characteristics. Statistical analysis then facilitates trend review and continuous improvement validation.
