Samsung’s latest Galaxy Note 7 battery recall may show proof that independent battery testing by companies, while common practice so far, may be changing. CTIA, which has certified more than 1,500 types of batteries over ten years, is discussing where the future of testing is headed.

CTIA, the U.S. Consumer Product Safety Commission and the IEEE worked together in 2005 to create a voluntary program for battery testing, which the CTIA administers, reported the Wall Street Journal. Tom Sawanobori, CTO of the trade group told Associations Now the Galaxy Note 7 battery recall is the first time there’s been such a big issue since then.

Most smartphone companies follow CTIA’s standards for testing which include third-party labs that go under scrutiny of the Institute of Electrical and Electronics Engineers (IEEE), however Samsung tests internally, Associations Now reported. While CTIA has certified 28 nationwide labs for third-party testing, Samsung is the only major manufacturer to use its own lab since 2009. The Samsung device was recalled last month and then discontinued last week after original and replacement units caught fire.

Eddie Forouzan, an IEEE committee member involved in setting the battery standard, told Associations Now he had an issue with self-testing, but the chair of the committee, Jason Howard, disagreed, stating that self-certifying is a common practice. The “approach was understandable out of an interest of protecting trade secrets and speeding up product releases,” he told Associations Now.
