Revision of D7176-06(2018) Standard Specification for Non-Reinforced Polyvinyl Chloride (PVC) Geomembranes Used in Buried Applications

Keywords

None Provided

Rationale

ASTM D2124 has been withdrawn in 2020 (under ASTM D20). Despite the method has been withdrawn, the goal of the analysis was the identification of certain resins, plasticizers, stabilizers, and fillers in PVC compounds, without specific quantitative analysis of the molecular weight (MW) of plasticizers, as specified by ASTM D7176. The analysis of MW was estimated from ASTM D2124 extract, but after further chromatography analysis from the extracted plasticizer solution. Clarify how to proceed with the measurement of plasticizer content and molecular weight
