temperature", "Highest relative humidity" and "Condensation"
Climatic ambient conditions ‑15 °C to +55 °C
Highest relative humidity < 60%, condensation not permissible
Mechanical ambient conditions vibration-free storage room v
rms
< 0.2 mm/s
Protection against chemical substances Protected in acc. with Class 1C2
Biological ambient conditions Suitable in acc. with Class 1B2
Duration • Six months for the above-mentioned condi‐
tions.
• Special preservation measures are required
for storage periods of 6 months up to a
