The impact resistance test in this standard allows only the use of a 20 lb weight, which requires a height of over 10 ft to achieve the energy required for most of the trade sizes. A review of F679, F794 and F949 (other PVC sewer standards) shows that they allow a weight of either 20 lb or 30 lb-keeping the height of 10 ft or less. This project is to add the option to use a 30 lb weight when performing the impact resistance test according to this standard.
