Our field engineers and trained technicians perform Cleanroom certification procedures in accordance with the latest IEST-recommended practices, International Organization for Standardization (ISO) standards, owner specifications, and our company’s Standard Operating Procedures (SOP). As a certified member of the National Environmental Balance Bureau (NEBB) and a member of the Institute of Environmental Science and Technology (IEST), we help clients achieve facility certification through the professional services of our highly trained staff. Neudorfer Engineers’ highly trained technicians provide accredited testing and certification of various cleanroom applications, including aerospace, automotive, electronics, semiconductor, optical, precision assembly, pharmaceutical, medical device, sterile compounding, health care, biomedical research, chemical, specialty gas, biotechnology, universities, and food industries. Depending upon the use of the cleanroom, the testing and certification are usually performed at initial installation and at specified intervals, whether semi-annually or annually. In each cleanroom, the concentration of airborne particles is controlled to specific limits. Cleanrooms are classified by the numbers of particles per cubic meter per minute. Sizes of particles which are controlled usually range from 0.1 to 10 micrometers. Room classifications are described in ISO-14644-1; “Cleanrooms and associated controlled environments-Part I-Classification of air cleanliness“. Cleanrooms range from ISO Class I through 9 and may be unidirectional (laminar), non-unidirectional (turbulent), or mixed airflow. Clients may choose from a variety of tests, depending upon their specific needs. NEI provides Cleanroom testing and certification according to the ISO Standards 14644-1, 14644-2 and 14644-3-Test Methods, and IEST document IEST-RP-CC006.3 including: Air Flow, Volume, Velocity, Uniformity Test Room Pressurization Non-Viable Particle Count Temperature and Relative Humidity Test Room Particle Counts NEI can also provide additional optional test services, including: Light Level Test Noise Level Test In-Place HEPA Filter Integrity Test Airflow Parallelism HEPA Filter Leak Testing (Bench Testing) Viable Particle Counting (Witness Plate) Visual Airflow Characterization (Smoke Test) Differential Pressure Gage Calibration. IAQ Testing and Monitoring of Industrial/Commercial Spaces With over 37 years of cleanroom troubleshooting, benchmarking and certification experience, Neudorfer Engineers works with the design and construction teams on our clients’ behalf to bring each project to successful completion and keep your cleanrooms operating optimal levels. We provide data analysis, evaluations, and recommendations of cleanroom test results to help the project team implement corrective actions and operational procedures to achieve performance that is equal to or better than industry standards and to minimize effects on sensitive spaces, including: Pre-audit consulting for ISO 13485.6.4.b & c pertaining to cleanrooms & controlled environments Contaminant control investigations and analysis. Review of Personnel Protocol, Housekeeping, and Custodial Procedures. Review of Operational, Maintenance, Housekeeping and Custodial SOP’ manuals & Protocol documents. Review of Airflow Management Practices. Since 1980, Neudorfer Engineers has been a leader in providing certification of contamination control services.
