On the journey of the certification and testing industry, GTG Group has continuously set new industry benchmarks with its outstanding professionalism and unremitting efforts. We are proud to announce that GTG Group - Guangdong Energy Storage Testing Technology Co., Ltd. (hereinafter referred to as "GTG-ESTL") has successfully passed the qualification review for UL Witnessed Test Data Program (TPTDP), becoming the first certification and testing institution in South China to obtain TPTDP qualifications for UL1642, UL2054, and UL/CAS 62368-1. This groundbreaking achievement not only marks the international authoritative recognition of our technical capabilities in the energy storage testing field but also provides customers with more efficient and convenient service guarantees.

What is TPTDP?

TPTDP, short for Testing Program Third Party Data Program, is a highly influential third-party testing data recognition program launched by UL (Underwriters Laboratories). Through TPTDP, authorized laboratories can conduct tests in accordance with UL standards, submit data for review, and once approved, products can obtain the UL certification mark.

Obtaining TPTDP qualification fully verifies GTG-ESTL’s outstanding testing capabilities in the battery/electric vehicle field. It also serves as strong evidence that our technical capabilities, management standards, and credibility have reached world-class levels.

TPTDP Capability Scope of GTG-ESTL

Advantages of TPTDP Compared to Traditional Witnessed Testing

Compared with the previous witnessed testing model, TPTDP offers the following key advantages:

1. Efficient Testing Planning & Shorter Cycles
   The testing plan is formulated independently by the TPTDP laboratory. Customers only need to send their products to GTG-Energy Storage Testing’s TPTDP laboratory and conduct sufficient communication before the test starts. This streamlines the process, significantly shortens the testing cycle, and greatly improves certification efficiency.

2. Cost Savings on Witnessing-Related Expenses
   For authorized test clauses, on-site witnessing by UL engineers is not required. This eliminates the need for customers to bear travel and accommodation costs associated with arranging witnessed tests, effectively reducing enterprise costs.

By choosing GTG-ESTL’s TPTDP laboratory for UL certification, enterprises can not only shorten the certification cycle and reduce costs but also receive full-process technical support from GTG’s professional team—from testing plan formulation to certificate issuance—ensuring every link is efficient and error-free.
