MIL-STD810H method 524.1 freeze-thaw, CCK-T series climate chambers

The purpose of this freeze-thaw test method is to determine the material’s ability to withstand the effects of moisture phase changes between liquid and solid, in or on the material, as the ambient temperature passes through the freezing point and the effects of moisture induced by transfer from a cold to a warm environment or from a warm to a cold environment.

This method is applicable to materials that will be exposed to temperatures above the freezing point while wet or in the presence of moisture, to induce physical changes in the material and evaluate resistance to distortion or jamming of moving parts, failure of bonding materials, seals, etc.

This method establishes three test procedures: diurnal cycle effect, fogging, or rapid temperature change.

DYCOMETAL’s CCK-T climatic chambers are designed to accurately reproduce the most demanding environmental conditions in compliance with the requirements of MIL-STD-810H, method 524.1, guaranteeing the ability to simulate thermal cycles and environmental conditions according to the most rigorous military standards. This allows the behaviour and resistance of equipment to be verified in the face of extreme temperature variations, ensuring its performance and durability in any operating environment.

With CCK-Ts, laboratories and testing centres have a robust, accurate and compliant solution to ensure the quality and reliability of their products.

CV series, vertical freezers for testing in accordance with MIL-STD method 502.7 – low temperature

Low temperatures have adverse effects on almost all basic materials. As a result, exposing materials to low temperatures can temporarily or permanently affect their performance by altering the physical properties of their constituent materials. MIL-STD 810, in its method 502.7, establishes the test conditions for low temperatures in order to obtain data that helps evaluate the effects of low temperature conditions on the safety, integrity, and performance of the material during storage, operation, and handling of systems and components. This ensures the safety, integrity and performance of the material during storage, operation and handling for all materials that are exposed to a low-temperature environment during their life cycle.

DYCOMETAL upright freezer cabinets have temperature ranges down to -70ºC, with different volume capacities and internal dimensions. Manufactured from robust materials, they allow the most demanding tests to be carried out. All this is controlled by an advanced microprocessor and associated software for recording the tests on a computer.

In addition, we offer tailor-made solutions according to customer requirements. Please consult our technical-commercial department for comprehensive advice.

CETM-70/1450T, chamber for thermal testing in accordance with MIL-STD-810 method 501.7

 One of the leading standards in environmental testing in the defence sector is MIL-STD 810, which covers the different environmental tests that samples must undergo to ensure their storage and operation throughout their useful life. This standard covers various test methods, and specifically, Method 501.7 is dedicated to high-temperature testing to evaluate the effects of high-temperature conditions on the safety, integrity and performance of the material, simulating conditions where temperatures (ambient or induced) are higher than standard ambient temperature. High temperatures can affect the performance of the material by modifying the physical properties or dimensions of the material or materials that compose it.

The DYCOMETAL climatic chamber, CETM-70/1450T, has been designed to comply with the tests indicated in this test method. The system has been adapted in volume to the customer’s needs. It has a reinforced floor for positioning the samples and two shelves for lighter samples. All of this is controlled by a 7″ touchscreen control panel with associated control and recording software on a PC.

CRT2V-70/540T, Thermal shock chamber for testing in accordance with MIL-STD 810 method 503.7

 Thermal shock chambers are essential for testing the thermal fatigue of samples, simulating sudden changes from cold to hot temperatures in a very short period of time in order to evaluate resistance, weak points and possible subsequent failures during use. Method 503.7 of the MIL-STD 810 standard establishes the environmental conditions necessary to perform this thermal shock test according to the type of sample to be tested.

The CRT2V-70/540T chamber has been developed to comply with the MIL-STD standard according to method 503.7. With a useful basket capacity of 540 litres, it allows for the testing of both small and medium-sized parts, performing the shock between -70ºC and +250ºC in less than 10 seconds.

At DYCOMETAL, we offer tailor-made solutions designed to meet the specific needs of each sector.

Environmental testing for UAS (drones) with DYCOMETAL climate chambers

The use of unmanned aerial systems (UAS), commonly known as drones, has grown exponentially in sectors as diverse as industrial inspection, precision agriculture, logistics and emergency management. This equipment must operate with complete reliability in highly varied and, in many cases, extreme weather conditions.

To ensure the safety and performance of UAS in real environments, it is essential to subject them to controlled environmental testing capable of faithfully reproducing the adverse weather conditions they will encounter in operation.

DYCOMETAL climatic and environmental simulation chambers allow the behaviour of drones and their components to be evaluated in relation to various critical factors:
– Extreme temperature testing
– Humidity and condensation testing
– Thermal cycles and thermal shocks
– Combined testing

The integration of environmental testing into the drone development and validation process not only improves technical reliability, but also increases user and operator confidence.

At DYCOMETAL, we offer the industry our experience and technology in climatic chambers and environmental simulation equipment, providing solutions tailored to the needs of each project.

Which option should I choose: air or water condensation/cooling?

 Climate chambers need to be cooled in order to perform effective heat exchange and cool the working volume. To perform this exchange, they have a condenser, which can be air-cooled or water-cooled, each with its own advantages and disadvantages. As we have seen above, air condensation is usually the standard for chambers with lower requirements. However, when high temperature gradients are required or the cooling unit’s performance is greater, it is advisable to use a water-cooled condenser, as this will help to reduce the heat and noise generated by the cooling unit. Furthermore, although air condensation is cheaper to install, it is less efficient, with higher operating costs due to its lower thermal efficiency, higher energy consumption and greater noise.

To do this, you need an external cooling unit (chiller) or a water cooling tower that supplies a continuous flow of clean, temperate water (between 5 and 30 ºC) to remove the heat generated during the cooling of the chamber, allowing you to handle more thermal load than air cooling. To avoid water consumption, the best option is a water recirculation unit, a closed circuit that continuously removes water. Another advantage of water-cooled units is that they are not as affected by the external conditions where the equipment is installed and generate less noise.
The disadvantage is that these types of systems require a more complex installation (pipes, pumps, etc.) and an additional investment for the external water cooling system.
