Process Engineering During the Life Cycle of a Product in the Twenty-First Century: Scope and Status of ISO/CD 10303-231

February 19, 2017

Author(s)

Mark E. Palmer, M Gilbert, F E. Hess

This document provides an overview of a new ISO standard, ISO/CD 10303-231, for exchanging process engineering information among process design and process simulation software tools and presents three views of this standard. First, it attempts to forecast

February 19, 2017

Author(s)

M E. McKnight

complishments and current standards development activities of the American Society for Testing and Materials (ASTM) Subcommittee E06.23, Lead Hazards Associated with Buildings, are summarized. Since the inception, the subcommittee has developed 24

Protected Elevators for Egress and Access During Fires in Tall Buildings (Abstract only)

February 19, 2017

Author(s)

Richard W. Bukowski

The events of September 11 have generated renewed interest in the use of protected elevators for egress and access. U.S. building codes contain requirements for accessible elevators for assisted evacuation of people with disabilities. Firefighter lifts

Protocol for Testing Mattress/Foundation Sets Using a Pair of Gas Burners

February 19, 2017

Author(s)

Thomas J. Ohlemiller

A dual burner apparatus has been developed for the purpose of assessing the flammability of a mattress/foundation combination in a manner that correlates with its real world fire behavior. This document sets out the detailed procedure for employing this

Public-Private Partnerships Pay Big Dividends: A Case Study of Cybernetic Building Systems

February 19, 2017

Author(s)

Robert E. Chapman

This paper presents a critical analysis of the economic impacts of past, ongoing, and planned collaborative research for developing and deploying cybernetic building systems (CBSs) in office buildings. NIST is participating in a public-private partnership

Quality Cement and Concrete - The Role of Testing Laboratories

February 19, 2017

Author(s)

J H. Pielert

Field inspection (including sampling) and laboratory testing of concrete and concrete-making materials are key activities ensuring that constructed facilities are durable and long lasting. Standards which promote the quality of testing are prepared by ASTM

Reactive Molecular Dynamics Simulations of the Thermal Degradation of Polymers: Comparison to Experimental Measurements

February 19, 2017

Author(s)

Marc R. Nyden, Stanislav Stoliarov, R Lyon, C S. Jee, Z X. Guo, P R. Westmoreland, Vadim D. Knyazev

The results of reactive molecular dynamics simulations of the thermal degradation of several polymers, poly(isobutylene), poly(methyl methacrylate), and poly(bisphenol A carbonate), are compared to experimental measurements of product distributions and

Real Fire Performance of Partition Assemblies: Insulated and Non-Insulated Assemblies

The National Institute of Standards and Technology (NIST) led reconnaissance to assess the performance of physical structures during Hurricane Katrina and Hurricane Rita. This paper summarizes 1) the major findings of the NIST-led reconnaissance team, 2)

Regulating Newton-Raphson's Method by Unconstrained Minimization of a Weighted Sum of Squared Residuals

February 19, 2017

Author(s)

D M. Lorenzetti

To control the Newton-Raphson solution of a nonlinear algebraic system, a descent method forces each step to reduce some norm of the residual errors. This prevents divergence, but risks stagnation in flat regions of the norm. Employing a family of cost
