DSRI has what it takes, and then some, to meet the needs of our extensive customer base. Across India and Asia-Pacific region offers unparalleled convenience and resources for the testing of defense technology.
We perform RDT&E services at our locations or at our customer’s government bases, contractor facilities or field trials. These services include CLASSIFIED and UNCLASSIFIED, accredited testing and evaluation to a wide range of industry standards and specifications including:
Environmental testing simulates the different climatic conditions and mechanical stress that products are exposed to during their lifetime. Environmental testing will expose weaknesses in a product’s design or performance that could occur in service, particularly at extreme levels.
In general, environmental tests demonstrate that your products have the build quality to work perfectly, no matter what the conditions. During testing, possible weaknesses can be identified and product improvements can be initiated at an early stage.
Environmental testing also helps demonstrate compliance of your products with international regulations, making it easier to access global markets. Environmental testing also boosts trust in your products.
Our facilities can simulate either single or multiple environmental conditions simultaneously. Our climatic chambers cover the extremes of temperature, altitude, humidity, temperature cycling, solar heating and corrosive atmospheres, which are continuously monitored by independent computer-controlled data collection systems. Our vibration shakers produce a range of profiles including; sinusoidal, random, sine on random, gunfire and bump among others, which are controlled and monitored by state of the art equipment and software.
We undertake all tests including the following:
The “Department of Defense Test Method Standard for Environmental Engineering Considerations and Laboratory Tests” covers the environmental factors encountered during the use of military equipment in all stages of its service life. MIL-STD-810 testing involves replicating these conditions in a controlled laboratory environment through the use of temperature, humidity, shock, vibration, acceleration and other simulation equipment.
“Type testing” is a protocol where valves or pumps are tested at the operating pressure and temperature ranges specified by the manufacturer.
Type testing also guarantees a valve against manufacturing defects for metallurgical failure analysis beyond the scope of in-house radiography, dye penetrant, hardness tests and XRF analysis. Our well-oiled team is well adept at carrying out Endurance Tests, Hydraulic Test, Seat Leak Test, Pneumatic Test, Pipe Wracking Test, Flow Coefficient Test, Torque Test, Life Cycle Test, SBN & ABN Test, Shock Test and Strip Test.
Failure Analysis: When a valve suffers a catastrophic failure, it is important to find out the root cause, in order to help insure that the event is not repeated. We combine the vast knowledge of our staff with a complete complement of in-house non-destructive evaluation equipment and pressure testing machines to help discover the “why” of valve failures.
In addition to the temperature and pressure testing extremes, the valves are also often required to be tested for fugitive emissions leakage during the test program. DSRI can perform type testing on valves of all sizes, materials and types.
We carry out type testing of valves or pumps as per many a standard including NES 375, MIL-STD 810G. In particular, we perform the following tests as per NES 375:
Shock and vibration testing ensures product performance under extreme conditions. Vibration testing and shock testing are used to simulate in a controlled laboratory environment the extreme conditions that a product may face during use, such as mishandling, dropping, and various modes of shipment.
Shock and vibration testing provides a wealth of benefits, such as:
Our vibration testing labs use state-of-the-art equipment to reproduce low and high frequency conditions, and to test products up to 5 tons in accordance with the requirements of MIL STD 810, MIL STD 167 & JSS 55555 among other regulations. Any additional test can be added quickly through our flexible schedule.
Our shock testing laboratories have a unique set of facilities designed to test the robustness and fragility of product samples and their packaging. We have several shock machines, a side impact machine, a compression machine, a precision drop tester and bounce facilities.
Furthermore, for long-term mechanical cycling with or without climatic conditions, our experienced engineers have the skills, facilities, and experience to build a solution for almost any testing challenge.
Depending on your product and its intended use, we will carry out the appropriate shock and vibration tests.
Electromagnetic compatibility (EMC) testing measures the ability of equipment or systems to function satisfactorily in their electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment.
Detecting rogue signals and electromagnetic interference is crucial to the all civilian & military appliances these days. Almost everything from a cellphone to a control panel onboard on vessel produces an electromagnetic field and can potentially threaten safety, efficiency or secret communications. MIL-STD-461F is one such standard test standard that establishes requirements for the electromagnetic compatibility (EMC) of devices and systems created for and used by several organizations.
EMC certifications are a mandatory requirement in most markets, including India, Europe, US, China, Korea, Australia and New Zealand. EMC testing is necessary to help you meet regulatory requirements, improve product performance and reduce the risk of costly non-compliance. A third-party EMC test lab can conduct conformity assessments and also help to strengthen your competitive position in the market. Our testing can cover all types of products, from small appliances to large defence industry machines.
We assist you to resolve any EMC regulatory issues, from design concept to final production. We provide a one-stop service that covers all your testing and certification needs. Our experts provide project management to ensure that your EMC tests run smoothly.
You can choose to have tests performed at our labs, on your premises or anywhere your product is installed.
We undertake the following tests:
