Revise current ANS: ASME B18.2.2 - 20XX, Nuts for General Applications: Machine Screw Nuts, Hex, Square, Hex Flange, and Coupling Nuts (Inch Series)

Angel L. Guzman Rodriguez 10/30/20
This Standard is intended to cover the complete general and dimensional data for the various types of inch series square and hex nuts, including machine screw nuts and coupling nuts, addressed by this Standard.


Create a new American National Standard (ANS): ASME HR-1 - 20XX, Power Generating Facilities: Continuous Power Output and Heat Rate

Michelle Pagano 11/08/20
This document will provide rules and methods for the determination of continuous power output and heat rate with the lowest achievable uncertainties for hydrocarbon fueled Rankine cycle power generating facilities. Implementation of a continuous performance monitoring program will be outlined.


Create a new American National Standard (ANS): ASME PHM-01 - 20XX, Guideline for When and Where PHM should be Integrated in Manufacturing Operations

Donnie Alonzo 10/26/20
The proposed guidelines will include recommended best practices to
(a) identify areas where operational efficiencies can be improved
(b) define use cases linked to desired safety, environmental, and cost?benefit factors as well as operational improvements
(c) establish a baseline of current maintenance practices and health?ready capability levels
(d) implement cost?effective equipment asset condition management (ACM2) strategies and measure their effectiveness in improving operational efficiencies


Revise, redesignate and consolidate current ANS: ASME Y14.39 - 20XX, Preferred Limits and Fits

Fred Constantino 10/31/20
This standard describes the limits and fits for mating parts. It defines terminology, symbols, preferred base sizes (first and second choices), and preferred tolerances (first, second and third choices). Tolerances for base sizes from 500 mm to 3150 mm are specified. Preferred limits and fits for sizes (first choice only) up to and including 20 in. and 500 mm are also included.


Revise current ANS: ASME Y14.43 - 20XX, Dimensioning and Tolerancing Principles for Gages and Fixtures

Fred Constantino 10/24/20
This Standard presents the design practices for dimensioning and tolerancing of gages and fixtures used for the verification of maximum material condition (MMC) size envelopes and virtual condition boundaries generated by geometric tolerances controlled at maximum material condition. Examples of gages used to inspect workpieces using regardless of feature size (RFS) are covered in an Appendix.
