Meet standard：
IEC 60068 Series - Environmental Testing International Standards
Military walk-in test chambers must comply with the IEC 60068 basic environmental test procedures, where IEC 60068-2-1 (Cold Tests) and IEC 60068-2-2 (Dry Heat Tests) specify military temperature testing ranges from -65°C to +200°C, with typical test durations of 48-96 hours.
MIL-STD-810 - US Military Environmental Engineering Standard
Section 516.7 explicitly requires walk-in test chambers to have rapid temperature change capability (≥10°C/min) and pass 24 thermal shock cycles, with chamber temperature uniformity controlled within ±2°C.
ISO 16750 - Road Vehicle Environmental Conditions Standard
For military vehicle component testing, Chapter 4 specifies that walk-in test chambers should achieve -40°C to +120°C temperature cycling while simultaneously simulating 5000m altitude (54kPa) low-pressure environments.
RTCA DO-160 - Airborne Equipment Environmental Tests
Temperature test chambers to maintain temperature gradients ≤3°C/m³ in the -55°C to +85°C range, while Chapter 24 (Sand/Dust Tests) specifies particle concentration at 10.6g/m³±7g/m³.
DEF STAN 00-35 - UK Defense Standard
Part 3 requires military test chambers to have triple-protection functions (anti-humidity/anti-salt spray/anti-mold), with mold tests lasting 28 days using test strains compliant with IEC 60068-2-10.
NATO AECTP 300 - NATO Environmental Testing
Clause 4.3.4 mandates walk-in test chambers to support -46°C to +71°C thermal shock testing with transition time ≤5 minutes and rate ≥15°C/min.
IEC 60721 - Environmental Parameters Classification
The standard categorizes military environments as Class 3K5 (shipboard), 4K5 (vehicle-mounted), etc., requiring test chambers to simulate combined temperature, humidity and vibration conditions.
ASTM E595 - Material Outgassing Tests
For aerospace materials, chambers must achieve vacuum levels of 5×10-5 Torr with quadrupole mass spectrometers to detect Total Mass Loss (TML) ≤1.0%.
ISO 9022 - Optical Instrument Environmental Tests
Part 12 specifies sand/dust test chambers must use ≥97% SiO2 content particles with adjustable wind speeds of 1-20m/s for military optical equipment testing.
EN 60068-3-6 - Test Chamber Calibration Methods
This European standard requires annual calibration of military test chambers, with sensor accuracy of ±0.1°C/±1%RH and 6-month calibration report validity.
