The
38、 rod shall then be rotated slowly against theindicator, and the deviation from straightness in any portion ofthe rod between the supports shall not exceed the permissiblevariations prescribed in Table 10. The deviation from straight-ness (throw in one revolution) is defined as the differencebetween
