The chemical resistance information for PVC pipe provided in the following tables is based on short-term immersion of unstressed strips of PVC in various chemicals (usually undiluted) and may be useful in assessing the suitability of PVC under unusual or specific operating environments. Results of this type of test can be used only as a guide to estimate the response of PVC. These tables provide guidance of industrial users of pipe for conveying the chemicals listed, rather than design criteria for sewers that may experience occasional exposures or when diluted by other wastewater discharges.
