We have the experience
to test your prototipes in
controlled enviromental
conditions
Its purpose is to subject a product or part of it to simulated environmental conditions of temperature and humidity to which the material will be exposed.
Our test laboratory, accredited by the A2LA accreditation entity in ISO IEC 17025, performs environmental simulation tests to meet the needs of industry.
It is currently necessary to carry out environmental simulations in electronic component climatic chambers in which the test is required to be performed while they are being energized.
Due to exposure to high or low temperatures, the materials can deteriorate over time, aging prematurely, while wet conditions can lead to condensation that damages the electronics internally.
SITEC LAB has the ability to test these components under methods accredited by the A2LA accreditation body such as PV 1200, IEC 600068-2-30, TS 956 Sec. 6.7,6.39.
We currently work with standards such as USCAR 21 for connectors, GS 95002-2 in lighting systems, among others. SITAC LAB will extend its scope to 2021 with ISO/IEC 17025 accreditation in electrical measurements.
We have measurement equipment, power supplies, data acquisition systems, etc. All our equipment has the traceability of accredited methods to offer a service that meets the standards
implemented.
Some of the sectors we serve are, automotive, aerospace, electronics, aeronautics, household appliances, among others.
SITEC LAB offers neutral salt spray, accelerated corrosion and cyclic corrosion tests in accordance with the main international standards such as ASTM B117, ISO 9227, PV 1210, GMW 14872, SAEJ 2334, serving all types of industry, mainly the automotive industry.
Every six months SITEC LAB participates in Proficiency Testing where more than 70 laboratories participate at an international level, placing us with excellent results in the evaluation of our personnel, equipment and materials.

SITEC LAB has a prototype based on the IEC 60068-2-18 standard for environmental systems.
The rain simulation is carried out with the help of sprinklers, which provide us with the necessary pressure and amount of water.
The exposure time is according to the amount of nozzles or sprinklers. The standard establishes the distance at which the sample will be placed in a “fixture” simulating the ideal operating conditions. It can be done with the sample energized and not energized.
The purpose of the test is to verify that the sample does not contain water inside at the end to meet the IP (Degree of Protection) acceptance criteria. < < < < < < < < < < < < < < < < <
It determines the filtration of dust in its components and its vulnerability in a certain quantity, pressure and time.
In recent years, several manufacturers of consumer electronics have become increasingly interested in designing devices that have a higher degree of protection, either from these or other types of elements, given that a wide variety of electronic products are used on a daily basis. Having such protection provides a great advantage to the consumer and distinguishes the manufacturer from others.
The automotive industry mainly tests its components under FMVSS 108, SAE J575 and
TL 956.

They determine the performance and reliability of the products. There are different types of vibrations: Sinusoidal, impact, shock, random or a combination of these, which simulate conditions that occur throughout the life of the products or during transportation periods.
SITEC LAB is the only third party laboratory in Mexico accredited with the ISO/IEC 17025 standard in this branch. Our tests are performed for the automotive, aerospace, electronic components and packaging industries with the ability to control temperature and humidity in the test by energizing the parts if required.
We work with national and international standards in particular: IEC 60068-2-6, IEC 60068-2-27, VW 80200, GMW 3172.
Our vibration system guarantees traceability and reproducibility thanks to our QMS Quality Management System.
Our staff is technically evaluated by the A2LA accreditation house and is constantly trained. < < < <
Endless standards and procedures are employed to ensure the reliability of any product, from testing the wear and tear of a car steering wheel to measuring the torque force of a stereo knob, each and every one of these tests serves a purpose to ensure confidence and reduce the risks involved.
The thermal shock test consists of subjecting a component to sudden temperature changes, this is achieved by using two chambers that are at controlled temperatures to generate thermal stress.
When making this type of change, some material properties may be closely studied, such as: thermal conductivity, thermal expansion coefficient, crack resistance or how temperature affects gloss or colour, in order to detect possible failure and thus know in what sense to provide greater protection and avoid future accidents.
SITEC LAB has the thermal shock method accredited under ISO IEC 17025 with A2LA.
SITEC LAB offers a wide range of testing services for the automotive, aeronautical, household appliances and electronics sectors, always following the highest quality standards, ensuring the reliability and repeatability of each of the results obtained.
Among the services are the following:
