11、ted.FOREWORD(This Foreword is not part of ASME Y14.36M-1996.)Subcommittee 36,Surface Texture Symbols,was formed in November 1974,and is a Subcommittee of the ASME Standards Committee Y14,Engineering Drawing and Related Documentation Practices.The Subcommittee is charged with the responsibility of es
12、tablishing surface texture symbols,and methods for specifying them on engineering drawings.The basis for this Standard is ASME B46.1-1995,Surface Texture,which covers other subjects related to surface texture,such as definitions of terms,instrumentation,precision reference specimens,roughness compar
13、ison specimens,and reference material such as notes on use and interpretation of profiling instruments,control and production of surface texture,and other methods of specification and measurement of surface qualities.This revision is also based on a review of and conforms in most respects with the i
14、nternational standard IS0 1302:1992,Technical Drawings-Method of Indicating Surface Texture.The following is a summary of the significant changes made to the 1978 Edition of this Standard.(a)The waviness designation is invoked by W,and a value placed in the symbol;(b)roughness values other than R,no
15、w have a place in the symbol;(c)other parameters can be invoked by a note;(d)the location in the symbol for designating processes now conforms with IS0 1302:1992;(e)the roughness cutoff or sampling length no longer has a default value of 0.8 mm(.030 in.).Suggestions for improvement of this Standard
