Electrical and non-electrical equipment for use in workplaces potentially at risk for explosive atmospheres must ensure a level of safety appropriate to the area of installation. Equipment going into an explosive atmosphere/environments, whether electrical or non-electrical, is subject to strict testing and certification requirements in many countries. The design requirements for products used in an explosive atmosphere differ significantly from those employed in a non-explosive atmosphere. Furthermore, there are key design differences depending on which type of explosive atmosphere they may be used in. It is therefore imperative to understand the what the design implications are at the start of the product design process.

We offer testing of the Ex products as per the below mentioned standards:

Medical devices save lives. The sooner you can get your medical device out to the market, the sooner it can help people. But before you can do that, you need to achieve medical device compliance. Patients and users expect medical devices to be safe. Using medical devices should improve their health and even save their lives.

That’s why proving medical device compliance is important. It guarantees patients that the device they are using is, in fact, safe.  And the ultimate goal of developing a medical device is to help patients. If your device isn’t safe, you’ll risk patients getting hurt. The best way to do it is to do medical device testing.

Applying to most electrical equipment,  the Low Voltage Directive (LVD) states electrical equipment can only be placed on the market if it does not endanger the safety of persons, domestic animals or other equipment and goods. It is mandatory to CE Mark products that fall within the scope of the Low Voltage Directive (unless it is excluded by other Directives).

Electrical safety testing is essential to ensure safe operating standards for any product that uses electricity. Various governments and agencies have developed stringent requirements for electrical products that are sold world-wide. In most markets it is mandatory for a product to conform to safety standards promulgated by safety and standard agencies.. To conform to such standards, the product must pass safety tests such as the high voltage test (also called as Dielectric voltage-withstand test or high potential test), Insulation Resistance Test, Ground (Earth) Bond and Ground Continuity Test and Leakage Current Test (also called as Line Leakage Test, Earth Leakage Current Test, Enclosure Leakage Current Test or Patient Leakage Current Test). These tests are described in IEC 60335, IEC 61010 and many other national and international standards.

In general, IEC 60335 is the most widely applied standard for electrical safety testing, especially for domestic appliances. Many safety testing standards in the world have been based on it. To safeguard workplace health and safety, many sections of the Occupational Health and Safety Regulation provide guidelines on electrical safety and the appropriate equipment required to work on low and high voltage electrical appliances.

Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment. EMC testing has been divided into two parts as detailed below:

We offer a lower cost EMC Testing service by specialising in smaller equipment and site testing (for larger equipment). QVC provides a fully calibrated and traceable test facility for the fast, accurate measurement of the EMI/EMC performance of your products.

Immunity testing – measures how a device will react when exposed to electromagnetic noise and other disturbances. The purpose of these tests is to gain a reasonable assurance that the device will operate as intended when used within its expected operating environment.

Emissions testing – measures the amount of electromagnetic noise generated by a device during normal operation. The purpose of these tests is to ensure that any emission from the device are below the relevant limits defined for that type of device. This, in turn, provides a reasonable assurance that the device will not cause harmful interference to other devices operating within its expected operating environment.

The common EMC testing standards are as follows:

• IEC 61326-1 – Electrical equipment for measurement, control and laboratory use – EMC requirements – Part 1: General requirements
