Testing of Electric Motors, drive systems made simple in Thermotron Environmental Test Chambers

Are you looking for an environmental test chamber to validate the performance of automotive electric motors, drive systems, then you are at the right place?

We offer environmental chambers that are:

  • Easy to use, integrate with the test rig
  • Smaller footprint
  • Better ROI – Can be used a normal environmental chamber when not in use for motor testing
  • Expandable

CAT III Compatible High Voltage Data Logger

Graphtec GL2000 data logger is used for line voltage monitoring and dynamic high speed measurement applications for industrial, transportation and manufacturing facilities.

GL2000 offers a maximum input voltage rating of Category III-rated 600 V True-RMS measurement in monitoring electrical signals connected to most distribution panels, circuit breakers and heavy equipment in industrial and manufacturing facilities.

GL2000 midi LOGGER HV complies with EN61010-1:2010 3rd standard adhering to the Category III 600 V working voltage (DC or AC-rms to ground) with peak transient voltage of 6,000 V. The unit has a withstand voltage of AC/DC 5,400 V for maximum one minute between channel-to-GND and channel-to-channel.

GL2000 is capable of sampling at 1MS/sec (or 1μs) on all four channels. This allows measurement of unique testing criteria for those problems and troubleshooting in research and development phases that require fine-tuning of AC or DC-driven motor systems. Along with monitoring temperature, pressure, flow and various other sensor signals, the pre-trigger recorder feature of GL2000 enables recording of transient data.

Why is ISO 13485 and Medical Device Testing so Important?

Consistent manufacturing quality is viewed to be critical to the safety and efficacy of medical devices. Medical regulatory bodies around the world, including the FDA, want to see processes and documentation that verify that a company manages the consistency of its manufacturing processes. ISO 13485 is aimed at ensuring a high level of consistency in the quality of manufacturing medical devices. It is typically combined with ISO 9001 to comprise a comprehensive ISO Quality System within a company.

Formal Process Validation involves Installation Qualification (IQ), Operational Qualification (OQ) and Performance Qualification (PQ). In Installation Qualification, each machine on the manufacturing line is installed correctly with proper connection to utilities and properly set up on the manufacturing line. Installation instructions are obtained from the equipment manufacturer. Documents are written to record these proper installation activities, including calibration certificates. Operational Qualification involves operating the machine as designed and instructed by the machine manufacturer to ensure that it performs the operations on the manufacturing line as intended. Performance Qualification involves examining variations in the operation of the machine due to normal process variation. This is often done by having three different operators run the machine in ostensibly the same way and documenting any difference in results.

What is 21CFR820 and How Does it Relate to ISO 13485?

CFR’s are Codes of Federal Regulations; that is, they are legal requirements in the USA. Title 21 of the Code of Federal Regulations (CFR) covers the broad area of food and drugs, as overseen by the FDA. Part 820 outlines the requirements for Quality Systems for medical device manufacturers; and Current Good Manufacturing Practice (CGMP) regulations that govern the manufacturing methods, facilities and production controls used in making medical devices. ISO13485 and 21CFR820 were “harmonized” a few years ago which clarified the legal requirements as to how companies are to make medical devices intended to be sold in the USA. Both involve Process Validation which involves IQ (Installation Qualification), OQ (Operations Qualification) and PQ (Performance Qualification).

TestResources test equipment is often needed for in-process tests within a validated medical device manufacturing process. A common example of this process would be qualifying each manufacturing lot of sterile package seals. TestResources can help you formally validate our equipment for your process by providing advice, IQ checklists, and other relevant documentation. We can also help you with appropriate checklists and documentation if you find it valuable to perform a formal gauge R&R assessment on your TestResources test equipment.

TestResources understands the medical device manufacturing industry and has provided assistance to several companies, including Medtronic, with their ISO 13485 process. Our test machines are highly successful in these IQ, OQ, and PQ qualifications, as well as Gauge R&R activities. Our engineers are aware that the ISO 13485 validation process is time-consuming and fast-paced. Knowing that your schedule is urgent, our engineers are ready to advise and assist you in validating your manufacturing process quickly. What sets us apart is that our engineers are the first to receive your call and can immediately provide you with your free testing advisement today. Give us a call now for help with your ISO 13485 testing.

STECH Offers Test Chambers, Ovens on Rent

Long lead times, order processing, the regulatory process has many times challenged and compelled our customers to drop, defer, or relocate their short-term priority projects that required Environmental test chamber for testing the final products.

STECH is listening to the customer demands and is pleased to formally Launch Test Chamber Rental program.

For more urgent test needs or for short term use we have a number of chambers available to hire (minimum 6 week hire period). We offer equipment on lease and buying options as well.  Please contact us for any of your needs, our team will suggest and quote suitable chamber and as well as assist you with startup and user training.

What is Simulation and Stimulation Testing ?

Here is a very basic overview of two broad types of environmental testing: simulation and stimulation. Each type of testing has unique goals, implementation methods, and specific types of test chambers to achieve testing goals.

Environmental testing can help reduce costs associated with recalls and warranties and help develop a reliable, durable product.
