To deliver products that meet tested standards and to support ongoing research and development, Kumwell has invested in establishing the Kumwell Laboratory, which was completed in 2013. It is the first and only testing laboratory in Southeast Asia dedicated to grounding equipment, lightning protection devices, surge protection devices, and lightning warning systems. The lab is accredited under the TIS 17025-2561 (ISO/IEC 17025:2017) standard, which specifies the general requirements for the competence of testing and calibration laboratories in the electrical field. This accreditation is recognized by the International Laboratory Accreditation Cooperation (ILAC), affirming the laboratory's technical competence and its ability to issue test reports that certify Kumwell products as high-quality, effective, and truly safe in accordance with international standards.

The laboratory is capable of conducting tests in accordance with IEC 62561 and TIS 3024 standards, including tensile tests, electrical resistivity tests, load tests, bending tests, and lightning impulse current/surge current tests. It also performs environmental simulation tests. Additionally, the laboratory can conduct equipment testing in compliance with various standards such as UL 467: Grounding and Bonding Equipment and IEC 61643: Low-Voltage Surge Protective Devices (SPD), among others.
