Assmann Polyethylene Tanks are ISO 9001: 2008 & NSF Certified

ISO 9001:2008 Certification

Assmann Corporation of America has been ISO Certified since 1994. An ISO certificate is not a once-and-for-all award, but must be renewed at regular intervals recommended by the certification body, usually around three years. Two types of auditing are required to become registered to the standard. Auditing by an external certification body and audits by internal staff trained for this process. By regular auditing, we are required to constantly improve our systems.

ISO audits engineering and manufacturing processes for effectiveness and continuous improvement. This monitoring helps Assmann Corporation set achievable goals, track our goals and best of all complete them. Assmann Corporation employee's commitment to the ISO program is second to none; our entire staff monitors each individual stage of our manufacturing process for errors and possibilities for improvement.

ISO forces Assmann Corporation to place the concept of process management front and center. "Process management" is the monitoring and optimizing of a company's tasks and activities, instead of just inspecting the final product. By regulating and monitoring our process, we continue to improve our products. This constant review makes us proactive rather than reactive to process design flaws and virtually eliminates poor quality products from ever being supplied.

What does this mean to you? Assmann tanks are designed and manufactured under strict quality control standards. Each tank we manufacture has its own quality control and routing card that links the product back to date of manufacture, raw material lot numbers, and processing times. This complete traceability is critical especially when governing laws are being created daily regarding bulk chemical storage.
