Hi,I need some information about impact test on Polyethylene ( gas distribution Pipeline) ?where can I find some useful information.Thank you

You could try to find the website for American Society for Testing Methods. You could also check various building codes. I would be surprised that polyethylene is acceptable for natural gas. It is permeable, and has poor heat and flame resistance.
