What does WC mean in relation to cylinders?

The term "WC" in relation to cylinders refers to "Water Capacity." This measurement indicates the maximum volume of water the cylinder can hold, expressed in liters or gallons. It is an essential specification since it helps determine how much liquefied gas the cylinder can safely contain, as the water capacity provides a standard reference for calculating the volume of gas that the cylinder can safely transport and store. This is particularly important for ensuring safety in the handling and use of LP-gas, as it influences the design, testing, and compliance regulations for pressure vessels. Understanding water capacity is crucial for operators to ensure that cylinders are filled correctly and to prevent overfilling, which can lead to dangerous situations.
