Why test with XTEMP
You are dealing with the people who know the equipment. XTEMP is the authorised distributor for Climats in South Africa — we don’t just operate the chamber, we service and calibrate it, and our applications engineers read the standard with you before the first thermocouple goes on. You get the applicable revision, severity and category confirmed up front, a profile built to match, and a report you can put in front of your customer.
Frequently asked questions
Which test standards can you run? The chamber covers the temperature, humidity and climatic-cycling clauses of IEC 60068, MIL-STD-810, MIL-STD-202, MIL-STD-883, RTCA DO-160, ISO 16750-4, GAM EG 13 and the JESD22 series — 37 standards in total. Download the full capability matrix for the clause-by-clause breakdown.
Can I do MIL-STD-810 testing in South Africa? Yes. We run MIL-STD-810 Methods 501 (High Temperature), 502 (Low Temperature) and 507 (Humidity) locally in Cape Town, through revision 810H.
What temperature and humidity range does the chamber cover? −70 °C to +180 °C for temperature, and +10 °C to +95 °C at 5–98 %RH for climatic (humidity) testing, with regulation stability of ±0.1 °C and ±2 %RH.
What size product can you test? The usable test volume is 400 litres — 700 mm wide, 650 mm deep, 900 mm high. We can advise on fixturing and thermal load during scoping.
Do you offer accredited testing? We provide test conditioning and reporting to the standards listed above. Where a formally accredited (ISO/IEC 17025) result is required, contact us and we will advise on the best route for your programme.
How do I book chamber time and what does it cost? Send us your specification and we will confirm what we can run, the price, and lead time. Chamber time is booked by the day.
Environmental Test Standards Matrix
Declared capability of the Climats EXCAL 4024 HA climatic test chamber. temperature, humidity and climatic-cycling test standards.
The chamber generates the full conditioning envelope required by the standard, within the declared temperature, humidity and rate limits. |
