1) The presence of a "+" sign indicates that the cylinder passed the hydrostatic test. 2) The "(tw)" marking typically refers to a test date or a specification, but without more context, it's not clear if it directly implies a 5-year retest cycle. However, many gas cylinders are indeed retested every 5 or 10 years depending on regulations and material. 4) The "84" likely indicates the year of manufacture or test, which would be 1984 in this context. The absence of clear guidance on retest intervals in the question makes the 5-year retest period a plausible but not definitively stated requirement based on the provided markings alone.
