Factory Location

Guangdong Derui Equipos de Prueba S.L. recently hosted a manufacturer from India at its factory in Dongguan, Guangdong for a technical exchange visit. The customer reviewed a temperature and humidity test chamber and an ozone ageing test chamber on site, and discussed test conditions, chamber configuration and delivery scheduling with the Derui engineering team.

The Two Chambers Reviewed

Both chambers were reviewed against the test work the customer carries out in its own laboratory, rather than a catalogue description.

Climate Testing

Temperature and Humidity Test Chamber

The chamber reproduces the heat, cold and humidity a product meets in storage, transport and service, so that weak points in enclosures, seals, coatings, adhesives and boards can be found before they reach the field.

Working volume, temperature and humidity range, ramp rate and dwell time are configured to the programme the customer's laboratory works to. Standards referenced for this type of chamber include cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits (cold), cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits (dry heat) and, for automotive work, ISO 16750.

Rubber and Polymer

Ozone Ageing Test Chamber

The chamber assesses how rubber and polymer components resist ozone attack while held under tension — vulcanized rubber, thermoplastic elastomers and cable sheathing being the usual specimens.

The unit reviewed is a combined ozone and humidity chamber: it operates from 10 °C to 70 °C, with an adjustable ozone concentration of 20–2000 pphm and a humidity range of 30–80 %.

What the Two Tests Are Used For

Climate testing and ozone ageing testing answer two different reliability questions, and the same laboratory often runs both side by side.

Temperature and humidity testing covers the widest range of products: it reproduces the heat, cold and moisture a unit meets in storage, transport and service, and is used to expose weak points in enclosures, seals, coatings, adhesives and printed circuit boards.

Ozone ageing testing targets elastomers specifically. Ozone attacks stretched rubber even at low concentrations and produces surface cracking, which is why cable sheathing, window seals, hoses and vibration mounts are routinely checked against an ozone ageing specification.

About Derui Testing

Guangdong Derui Equipos de Prueba S.L. manufactures environmental test chambers for reliability and durability programmes — temperature and humidity, thermal shock, altitude, salt spray, dust and rain (IP), UV and xenon weathering, solar simulation, battery safety and abuse testing, and custom walk-in rooms. Systems are built to the test standards customers work to, including the IEC 60068, ASTM, ISO and MIL-STD series.

Typical applications span electronics and semiconductors, automotive and EV, aerospace and defence, telecommunications and new-energy battery manufacturing.

Preguntas Frecuentes

Can overseas customers visit the Derui factory?

Yes. Derui regularly hosts customers from overseas at its factory in Dongguan, Guangdong. Visitors can go through a chamber in person, look at the control system, and confirm voltage, chamber footprint and lead time before ordering.

Which standards can a temperature test chamber be configured to?

Common references are IEC 60068-2-1 for cold and IEC 60068-2-2 for dry heat; automotive programmes frequently follow ISO 16750 or a customer-specific procedure. The profile is confirmed with the customer before production.

What is an ozone ageing test chamber used for?

It exposes rubber and polymer specimens to a controlled ozone concentration while they are held under tension, so that surface cracking can be observed and measured. It is a routine check for cable sheathing, seals, hoses and elastomeric components.

How do I arrange a factory visit or request a quotation?

Send your test standard, specimen or product dimensions and the chamber size you need through the contact page. The team will confirm a configuration, a quotation and, if required, a date for the visit.

Planning a factory visit, or need a chamber quotation?

Send us your test standard, specimen dimensions and the working volume you need — we will come back with a configuration, a quotation and a visit date.
