API Publ 328 is a technical API document focused on the laboratory evaluation of candidate liners for secondary containment of petroleum products. For buyers assessing material suitability, it provides a practical reference for understanding how liner candidates may be evaluated before use in containment applications. The document is relevant where petroleum storage or handling facilities need confidence in liner performance, compatibility, and overall suitability for secondary containment service. Teams involved in engineering, procurement, QA/QC, and operations may use it when reviewing materials for specification, selection, or technical verification.

Overview of API Publ 328

API Publ 328 is a published API technical reference that addresses the laboratory evaluation of potential liner materials intended for secondary containment of petroleum products. As an API document, it serves as a recognized industry source for technical review rather than a field instruction manual. Its focus is especially useful when a project or facility needs a consistent basis for comparing candidate liners during design, procurement, or materials review. The 1995 publication date and 149-page length indicate a substantial reference for technical decision-making in containment-related work.

Common use cases of API Publ 328

API Publ 328 is commonly relevant in petroleum industry projects where secondary containment liners are being considered for tanks, storage areas, terminals, or other containment-related installations. It may support engineering teams during material evaluation, procurement staff during product review, and QA/QC or inspection personnel when checking whether a liner candidate aligns with project expectations. Operations and maintenance groups may also reference it when planning containment upgrades or assessing replacement materials. In practice, it helps establish a more consistent technical basis for liner selection and review.

Benefits of using API Publ 328

API Publ 328 helps organizations approach liner selection for secondary containment with a clearer technical reference. That can improve procurement consistency, support engineering review, and reduce uncertainty when comparing candidate materials for petroleum service. It is also useful for aligning project teams around a common evaluation basis, which can aid quality control and reduce the risk of selecting an unsuitable liner. For facilities that rely on containment integrity, the document offers practical value in technical planning, documentation, and review workflows.
