Spilltest

Spilltest refers to a class of product safety and performance tests designed to evaluate how much liquid a container, vessel, or device leaks or spills when subjected to handling and use. It is used to assess containment performance, consumer safety, and regulatory compliance across a range of industries, including packaging, beverage vessels, automotive fuel systems, laboratory equipment, and industrial containers.

Tests typically involve filling the item to a specified level, sealing or closing as required, and exposing it to motions such as tilting, shaking, vibration, or impact. Measurements may include the volume spilled, leakage rate over time, splash distance, or the time to initial spill. Test conditions often simulate real-world scenarios such as transport, handling, or regular use, and are documented with details on sample identifiers and environmental parameters like temperature.

Variants of spilltest procedures vary by industry and jurisdiction. Common categories include static spill tests, dynamic tilt or rotation tests, and vibration or drop tests. In packaging and consumer products, spilltests support labeling claims, leak-resistance ratings, and compliance with safety regulations, while in industrial contexts they inform design improvements and quality assurance programs.

Limitations include sensitivity to test setup, liquid properties (viscosity, surface tension), and container geometry. Spilltest results provide comparative data that support risk assessment and design iterations rather than absolute guarantees of spill-proof performance.
