About This Item
ASTM F1144 is the standard specification for a manhole cover assembly designed to be bolted, semi-flush, oiltight, watertight, and hinged. It provides a focused technical reference for evaluating and procuring cover assemblies where secure closure and controlled access are important. By defining this type of assembly, the standard helps support consistent product selection, quality expectations, and compatibility with project requirements in applications that call for reliable sealing and durable hinged construction.
Overview of ASTM F1144
This ASTM standard addresses a specific manhole cover assembly configuration rather than a general-purpose cover. The title indicates key performance and design features: bolted closure, semi-flush installation, oiltight and watertight sealing, and a hinged arrangement for access. As a specification, ASTM F1144 is typically used as a technical basis for product conformity, purchasing decisions, and review of assemblies intended to limit leakage while maintaining practical access for inspection or maintenance.
Common use cases of ASTM F1144
ASTM F1144 is commonly referenced when specifying manhole cover assemblies for installations where sealing and controlled access are important. It is relevant to infrastructure or equipment openings that need a bolted, hinged cover with reduced exposure to liquids. In procurement and fabrication workflows, the standard may guide product selection, submittal review, and verification of assemblies intended for semi-flush mounting and tight closure. The designation helps buyers and engineers communicate a clear performance target.
Benefits of using ASTM F1144
Using ASTM F1144 can improve consistency in specification writing and product comparison by identifying a clearly defined manhole cover assembly type. It supports compliance-oriented procurement, helps reduce ambiguity during review, and may aid quality control by establishing a shared technical reference. For project teams, the standard can simplify evaluation of bolted, hinged covers intended to be oiltight and watertight, while also helping manage risk related to fit, sealing, and operational access.
