During the test, all six sets used for JA Solar's type-1 modules passed the UL Class A fire test conducted by Intertek, making JA Solar the first company mass producing photovoltaic modules in China to pass the test.

In recent years, as the installation of solar electricity generation has been rapidly grown worldwide.

The standard and criteria for the reliability certification of PV modules have been constantly updated and expanded in order to meet the increasing demand for PV products.

This is to ensure better quality and higher reliability from the end user of solar electricity, as well as the more stringent safety, environment, and hazard regulations for PV installations by legislatures and governments at various levels.

The Class A fire test for Type 1 PV modules set forth by UL-1703 requires the tested module to endure direct torch burning for more than 10 minutes from gas flame.

The criteria of this Class A test is far stricter than that of the previously commonly accepted Class C standard, which only requires the tested PV module to take four minutes of direct torch.

It turned out that, during the Class A test conducted at Intertek, the JA Solar's Type-1 modules subjected to the test not only withstood the inferno-like heat without becoming self-flammable; the flame torch was not even able to burn through the PV panel.
