Hindustan Petroleum Corporation [HPCL] — mandatory lpg checking

Address:

Pune, Maharashtra, 411044

My gas distributing agency is insisting on mandatory gas checking for household lpg connection. They are informing that unless this is done they will not deliver new refilled cylinders. Why they are forcing on us eventhough we have not raised any complaint.

Is it mandatory and is there any govt, rule in this regard. Pls let us know when the govt has releasde the notification.
