~ \Foreword

(This Foreword Is not a pari 01 American Standard Safety Code for Building Construction: Safety Requircments for Workmen'.l\oiats, AIQ.41963.)This standard is a revisiono Section 10, Special Requirements for Workmen's Elevator Cars, Part 11,Hoists and Elevators, of American Standard Safety Code for Building Construction, AIO.21944. When Sec.tional Committee AIO was reorganized in 1956, it decided to issue each revised section of the 1944 editionseparately. This standard is the first o f the revised sections to be approved by ASA.Mr. George C. Reppert, Code Engineer, National Elevator Manufacturing Industry, Incorporated, was chair.man of Subcommittee AI0-4 on Safety Requirements for Workmen's Hoists, responsible for draIting thisAmerican Standard AIO.4-1963.The ASA Sectional Committee on Standards for Safety in the Construction Industry, AIO, which developedthis standard, had the following personnel at the time of approval:
