Cylinder tare weight is the weight of the cylinder plus the what without the product?

The tare weight of a cylinder refers specifically to the weight of the empty gas cylinder itself, including any permanent fittings that are attached to it. In this context, the valve is considered a permanent component of the cylinder. Therefore, when asked about the tare weight, it is understood to include the cylinder plus the valve, while excluding any gas or product contained within.

By understanding this, it’s clear that the cylinder’s tare weight is accurately represented when considering the valve as part of the weight. Packaging, labels, or regulators are not incorporated into the tare weight calculation, as they do not contribute to the fundamental structure or function of the cylinder in terms of storing gas. Hence, the correct pairing for how tare weight is defined revolves around the inclusion of the valve.
