SECTION 66

1. In the case of a periodical payment to which this Article applies, the rate of the benefit, increased by the amount of any family allowances payable during the contingency, shall be such as to attain, in respect of the contingency in question, for the standard beneficiary indicated in the Schedule appended to this Part, at least the percentage indicated therein of the total of the wage of an ordinary adult male labourer and of the amount of any family allowances payable to a person protected with the same family responsibilities as the standard beneficiary. 2. The wage of the ordinary adult male labourer, the benefit and any family allowances shall be calculated on the same time basis. 3. For the other beneficiaries, the benefit shall bear a reasonable relation to the benefit for the standard beneficiary. 4. For the purpose of this Article, the ordinary adult male labourer shall be-- (a) a person deemed typical of unskilled labour in the manufacture of machinery other than electrical machinery; or (b) a person deemed typical of unskilled labour selected in accordance with the provisions of the following paragraph. 5. The person deemed typical of unskilled labour for the purpose of subparagraph (b) of the preceding paragraph shall be a person employed in the major group of economic activities with the largest number of economically active male persons protected in the contingency in question, or of the breadwinners of the persons protected, as the case may be, in the division comprising the largest number of such persons or breadwinners; for this purpose, the international standard industrial classification of all economic activities, adopted by the Economic and Social Council of the United Nations at its Seventh Session on 27 August 1948, and reproduced in the Annex to this Convention, or such classification as at any time amended, shall be used. 6. Where the rate of benefit varies by region, the ordinary adult male labourer may be determined for each region in accordance with paragraphs 4 and 5 of this Article. 7. The wage of the ordinary adult male labourer shall be determined on the basis of the rates of wages for normal hours of work fixed by collective agreements, by or in pursuance of national laws or regulations, where applicable, or by custom, including cost-of-living allowances if any; where such rates differ by region but paragraph 6 of this Article is not applied, the median rate shall be taken. 8. The rates of current periodical payments in respect of old age, employment injury (except in case of incapacity for work), invalidity and death of breadwinner, shall be reviewed following substantial changes in the general level of earnings where these result from substantial changes in the cost of living.
