Overview
Following installation of the active vibration isolation system, vibration environment measurements were conducted to verify that laboratory operation raises no usability issues.
Measurement date: 2016. 12. 27 (Tuesday), Measuring technician: Lim Jong-wook (Senior Engineer), DAEIL SYSTEMS
Measurement location: Hankook Tire Technodome, Daejeon, 1st floor research building
Equipment model: HITACHI SEM (SU8010)
Measurement conditions and results
Measurement conditions: Responses were measured on the isolation table top slab and on the slab floor of the R&D annex.
Summary of measurement results
| Test Condition | VC-Class Z | VC-Class X | VC-Class Y |
|---|---|---|---|
| Building floor | A (36.9 µm/s) | D (5.1 µm/s) | D (5.4 µm/s) |
| Isolation table top | F (1.3 µm/s) | G (0.4 µm/s) | G (0.4 µm/s) |
The isolated floor slab supporting the workstation measured VC-Class A on the vertical axis and VC-Class D on both horizontal axes. The tabletop above the isolator logged VC-Class F on the vertical axis and VC-Class G on both horizontal axes—performance regarded as excellent, with VC-Class plots attached.
Measurements will be repeated with the adjacent annex floor active while large metrology loads run next door so the platform may be returned for tuning; a follow-up trip is planned for January 3, 2017.

Notes:
1. As measured in one-third octave bands over 8-80 Hz (VC-A/B) or 1-80 Hz (VC-C through VC-G).
2. Detail size refers to width in microelectronics fabrication or particle size in medical research.
