Can photovoltaic module bag impact machine be used interchangeably with automotive glass impact machine?

Not directly applicable, the principle is similar, but the standards, impact bodies, sample fixtures, and judgment conditions are different;
Ordinary photovoltaic bag machines cannot be directly used for automotive glass certification testing and can only be used as internal reference tests.
1. Common points:
Both belong to the principle of shot bag pendulum impact, which relies on the swinging of heavy bags to impact glass and assess whether the glass can penetrate and fragment safety performance after being subjected to large mass flexible impact; The hardware structure of the photovoltaic bag machine and the building safety glass bag equipment are of the same origin.

2. Core differences (key points cannot be directly shared)
① Different execution standards
Photovoltaic module bag impact machine: According to IEC 61730 2 MST32 (module rupture test), it is specifically designed to test complete photovoltaic modules (with batteries, adhesive films, and backboards), simulate human impact, and evaluate the risk of puncture after rupture. Impact bag: 45.5kg lead bullet bag, specific diameter and filling ratio; The sample is a whole photovoltaic module, and the sample frame is suitable for large-sized photovoltaic panels.
Safety glass pouch test: According to GB 9656 ECE R43, For car laminated front windshields; The sample is a cut automotive glass sample with strict requirements for sample size, clamping rubber hardness, and clamping gap; There are exclusive regulations for the weight, swing radius, and rubber pad specifications of the impact bag according to automotive standards. There are still a large number of ball impact projects (227g steel balls, etc.) for car glass, which cannot be done by the ammunition bag equipment.
② There are significant differences in sample fixtures and jigs
Photovoltaic equipment framework: adapted to photovoltaic panels, clamping method adapted to the four sides of the component, rubber pads according to photovoltaic standards;
Automotive glass pouch tooling: There are mandatory regulations on rubber hardness, compression capacity, and clamping clearance; Directly using photovoltaic racks to install small car samples does not meet the clamping conditions, and the test results are not recognized by the certification body.
③ Different experimental judgment logic
Photovoltaic: Focus on whether there is a risk of injury after the module ruptures, and ensure that the internal circuits and insulation of the module do not have any dangerous states;
Car windshield: The key assessment for shotgun bags is that they must not penetrate, the bag must not touch the flat surface of the back of the sample, and the interlayer film must wrap around the fragments. The judgment conditions are different.
