60 STAT.] 79TH CONG. , 2D SESS.-CH. 709-JULY 31, 1946 Social Security Act, or if he is in all other respects partially insured but would be neither fully nor currently insured under the Social Security Act, or if he has no wage quarters of coverage." SEC. 204. A new subsection is added to section 1 as follows: "(p) The terms 'quarter' and 'calendar quarter' shall mean a period of three calendar months ending on March 31, June 30, September 30, or December 31." SEC. 205. Section 2 (a) is amended by substituting for all that portion of the subsection after the first numbered paragraph the following: "2. Women who will have attained the age of sixty and will have completed thirty years of service. "3. Individuals who will have attained the age of sixty and will have completed thirty years of service, but the annuity of such an individual shall be reduced by one one-hundred-and-eightieth for each calendar month that he is under age sixty-five when his annuity begins to accrue. "4. Individuals having a current connection with the railroad indus- try, and whose permanent physical or mental condition is such as to be disabling for work in their regular occupation, and who (i) will have completed twenty years of service or (ii) will have attained the age of sixty. The Board, with the cooperation of employers and employees, shall secure the establishment of standards determining the physical and mental conditions which permanently disqualify employees for work in the several occupations in the railroad industry, and the Board, employers, and employees shall cooperate in the pro- motion of the greatest practicable degree of uniformity in the stand- ards applied by the several employers. An individual's condition shall be deemed to be disabling for work in his regular occupation if he will have been disqualified by his employer because of disability for service in his regular occupation in accordance with the applicable standards so established; if the employee will not have been so dis- qualified by his employer, the Board shall determine whether his condition is disabling for work in his regular occupation in accord- ance with the standards generally established; and, if the employee's regular occupation is not one with respect to which standards will have been established, the standards relating to a reasonably compar- able occupation shall be used. If there is no such comparable occu- pation, the Board shall determine whether the employee's condition is disabling for work in his regular occupation by determining whether under the practices generally prevailing in industries in which such occupation exists such condition is a permanent disqualification for work in such occupation. For the purposes of this section, an employee's 'regular occupation' shall be deemed to be the occupation in which he will have been engaged in more calendar months than the calendar months in which he will have been engaged in any other occupation during the last preceding five calendar years, whether or not consecutive, in each of which years he will have earned wages or salary, except that, if an employee establishes that during the last fifteen consecutive calendar years he will have been engaged in another occupation in one-half or more of all the months in which he will have earned wages or salary, he may claim such other occupation as his regular occupation; or "5. Individuals whose permanent physical or mental condition is such that they are unable to engage in any regular employment and who (i) have completed ten years of service, or (ii) have attained the age of sixty. "Such satisfactory proof shall be made from time to time as pre- scribed by the Board, of the disability provided for in paragraph 4 727 49 Stat. 620. 42 U. . C.. 1305; Supp. V,§ 401 et seq.
