Cage Sampler:
7.3.1  A cage sampler shall be constructed of a spark-reducing metal, appropriately sized to hold the container, typically a 1 L (1 qt) bottle.

Cage samplers may be used to obtain spot, running and all-levels samples.
The use of a sampling cage, or any sampling process that avoids the need to transfer the sample into an intermediate sample container, is preferred for samples used for volatility testing.
