Cylinder tare weight refers to the weight of the cylinder plus what?

Cylinder tare weight refers to the weight of the empty cylinder itself, including any integral components but excluding the contents of the cylinder. This means it reflects the weight of the cylinder together with the valve attached to it, as the valve is considered a part of the overall assembly when determining the tare weight.

When dealing with gas or liquid in the context of tare weight, those contents are not included since tare weight is meant to indicate how much the cylinder weighs when it is not filled. Similarly, while a cap may be part of the assembly for some cylinders, it is typically the valve that is consistently accounted for in tare weight assessments. Therefore, the correct interpretation of tare weight focuses on the weight of the cylinder plus the valve, highlighting the importance of that component in understanding the total unfilled weight of the cylinder.
