INTRODUCTION The aim of the present study was to investigate whether the concentration of arsenic (As) released from gray or white mineral trioxide aggregates (MTAs) met the requirement of the International Standards Organization (ISO) for dental cements. METHODS Sample preparations were carried out according to the ISO methods. After centrifugation of dissolved samples, As (III) concentratio...

The U.S. Army Aeromedical Research Laboratory conducted a research program to develop a new methodology for health hazard assessment of tactical ground vehicle rides. This paper describes the new method and compares the health risk prediction using the new multiple shocks standard International Standards Organization (ISO 2631-5) to predictions by the current whole-body vibration (WBV) standard...

Background & Aims: Nowadays, new attitudes of clients, patients and students toward the quality of health care services, have led to unifying different systems in educational centers, which has been recognized as quality management system. The ISO standard series have created systems that integrate intra and inter organization processes to improve the quality of health services. The aim of the ...

2 Machine tool performance from the point of view of compliance to tolerances, surface definition, etc., is determined essentially by the accuracy of machine movement. For precision machining it is therefore important to measure and, if necessary, compensate for deviations in motion. Standards and directives for inspecting machine tools, such as ISO 230-2, ISO 230-3, ISO 230-4 and VDI/DGQ 3441,...

Computer character sets are not adequate for encoding texts any language, even in modern English. In all likelihood this will remain the case for some time to come, though a major improvement in the situation is approaching with the implementation of the new ISO 10646 universal coded character set. Because of the present limitations, the standards committee which drew up SGML included one type ...

Although business rules have been largely used in database modeling, very little can be found in requirements engineering literature. Many articles have been written about the use of business rules but only a few on how to elicit them. This article focuses on business rules as prescribed procedures that should be followed to achieve the business’s goals. Companies that are according to ISO 9000...

The growing adoption of safety standards in the automotive industry results in an increasing interest in as well as an increasing uncertainty about software tool certification and qualification. With ISO 26262 on the horizon, new tool qualification requirements need to be understood and implemented by automotive software practitioners. This paper summarizes the tool qualification approach of IS...

Information security is concerned with the requirements of availability, integrity, and confidentiality of information’s assets, which are fundamental to the long-term survival of an organization. Information security relies in risk management for security risks identification, evaluation and treatment, according to the ISO 31000. The methodologies supporting information security implementation...

Private voluntary standards such as the International Organization for Standardization’s (ISO’s) 14000 series have played an increasingly important role in encouraging corporations to adopt more sustainable business models on their own initiative and not in direct response to governmentally mandated requirements. ISO standards have a number of benefits, including promoting international uniform...

Whereas current engineering practice focuses on functional requirements, considerations other than the function (e.g., safety; security; maintainability) are relegated into a category (unfortunately) called “non-functional requirements.” Although ISO/IEC/ IEEE 24765 §3.1900 defines this term as “a software requirement that describes not what the software will do but how the software will do it,...
