Most design codes require stiffened cylinders to be made circular to within ½ per cent on radius, and large penalties are incurred by exceeding the shape tolerance. The methods specified for checking on circularity vary greatly and they are vague in some cases and illogical in others. Two methods of measuring shape are presented, and it is shown that extreme care must be used in analysing the results obtained from chord gauge readings which are often the most convenient to take. The accuracy of the two methods is compared.
