AS A 830 2-19...J:3, was crea ted fr orn the eight-page document referred to n i the fi rst paragraph This document was reaffirrned in 1952 and widely accepted a s a safety st a nd a rd Dueto changes in d esign, advancernent in techniques, and g eneral interest of lab or and in dustry n safety, the Sectional Committee, under i he t joint sponsorship of A SME and th e Nava l Fac ilities Engineering Command, U S Depar t ment of the Navy, was reorganized a san A m e ric e n Nati onal Standards Comm it t ee on Ja n uary 31, 1962, w it h 39 members representing 27 n ati on a l organiza­ tions The f ormat of the previous code was c hanged so that separate v o l urnes ( each complete as to construction a nd i nstallatíon: inspection, testing, and rnaintenance: and operation) would cov er the different types of equipment i n cluded in the scope of 830 In 1982, the Committee was reorganized a s a n Accredited Organization Committee, operating under procedures developed by ASME and accredited by the Arnerican Nationa l Standards Institute This Stan d ard presents a coordinated set of rules that may serve as a guide to govcrnment and other regulatory bodies and municipal authoritíes responsible far the guarding and inspection of the equi p ment falling within its scope The suggestion s leading to accident prevention are given both as mandatory and advisory provisions; compliance with both types n1ay be r equired by employers of their employees In case of p ractica! difficulties, new dcvelopments, or unnecessary hardship, the ndministrative or regulatory authority may grant variances from the literal requirements or permit the use of other devices or methods but only \.Vhen it is clearly evident that an equivale n t degree of protection is thereby secured TO secure uniform application and interpretation of this Standard, administra­ tive or regulatory authoritie s are urged to consult the 830 Committee, in accordance with the format described in Section III, before rendering decisions on disputed points This volun1e of the Standard , \.\1hich ,vas approved by the 830 Corrlmittee and A S ME, \.Vas approved by ANSI and d esignated a s a n American Nationa!
