Beiguang Precision Instrument and Jiangsu Sangruitai Environmental Protection New Material Resistance and Voltage Endurance Equipment Successfully Cooperate

Recently, cooperation in the field of environmental protection new materials in Jiangsu Province has mainly focused on solid waste resource utilization, lithium battery materials, and other directions, such as the Jiangsu Xitai Environmental Protection New Material Manufacturing and Research and Development Base project (with an investment of 350 million yuan). Due to the need to test lithium battery materials, one BEST-380 volumetric surface resistance tester and one BDCZ-5KV withstand voltage tester were purchased on September 8, 2025.

Equipment functional adaptability

The BEST-380 multi material compatibility testing capability supports volume/surface resistivity detection of solid, liquid, and powder materials. It is designed using the three electrode method to avoid leakage errors during liquid testing and meets the analysis needs of Sitong Testing for diverse samples.

Coverage of military and industrial standards
The equipment strictly follows domestic and international standards such as ASTM D257 and GB/T 1410-2006, meets the high temperature/radiation resistance environmental testing requirements of military materials (such as carbon fiber reinforced resin), and adapts to the certification needs of Sitong Testing in the material field.

Intelligent data management
It has the function of generating testing reports that comply with ISO, IEC and other standards with one click, which improves the data processing efficiency of third-party testing institutions.

380 Core International Standards

ASTM D257 Standard Test Method for DC Resistance or Conductivity of Insulation Materials

ISO 1853 Specification for measuring electrical resistivity of conductive and anti-static rubber

ISO 3915 Test method for volume resistivity of conductive plastics

Core equipment for cooperation: BDCZ-5KV withstand voltage tester

Function and Application: This instrument is mainly used for testing the breakdown voltage, breakdown strength, and withstand time of solid insulation materials (such as plastics, rubber, ceramics, films, resins, etc.). It supports power frequency AC or DC voltage modes and is suitable for insulation safety performance testing of new energy battery materials, thermal conductive materials, flame retardant powders, and other products.

Technical parameters:

Output voltage range: AC/DC 0-5KV

Boosting rate: adjustable in multiple stages from 0.1KV/S to 3.0KV/S (or 5.0KV/S)

Compliant with national and international standards such as GB1408-2016, GB/T1695-2005, ASTM D149, etc

Support wireless Bluetooth data transmission to improve detection efficiency

Strategic synergy: promoting the substitution of domestic testing equipment and industrial integration

Accelerate the process of replacing domestic instruments
BDCZ-5KV and BEST-380 have previously been purchased in bulk by BYD for use in power battery material testing. This cooperation further validates the localization competitiveness of Beiguang Precision Instrument in the field of testing equipment, and promotes the extension of import substitution to the field of new materials.

Deepen the linkage between industry, academia, research and application
The cooperation between the two parties echoes the industry trend of "integrated innovation and development of new materials and scientific instruments" (such as the agenda of the Suzhou Industry Forum in 2024), and through iterative testing technology, it feeds back material research and development innovation, forming a "technical demand equipment upgrade industrial application" closed loop.

Background and positioning of cooperation

Jiaxin New Material Requirements: The introduction of BBDCZ-5KV and BEST-380 equipment aims to improve the product quality testing system, especially for the insulation performance testing of its produced thermal conductive materials, flame retardant powders, and other products, providing key technical support for the quality control upgrade during the IPO sprint stage.

Market performance of Beiguang Precision Instrument: BDCZ-5KV and BEST-380 have been purchased in bulk by BYD multiple times and applied in the testing of power battery materials, marking the accelerated replacement of domestic testing equipment in the field of new energy.
