The majority of information is contained in 2 of its sections: Management requirements Section 4 Technical requirements Section 5 Management requirements pertain to the operation and effectiveness of the quality management system within the laboratory.
The requirements are similar to ISO This clause is divided into fifteen chapters, described below. Management Requirements An organizational structure, as well as responsibilities and tasks of both management and staff should be defined.
Examples include commercial marketing or financing departments. A quality assurance manager should be appointed. All personnel should be free from any commercial or financial pressure that could adversely impact the quality of calibration and test results.
Management System This chapter describes how to ensure that a management system is implemented, maintained, and continually improved.
There should be policies, standard procedures and work instructions to ensure the quality of test results. There should be a quality manual with policy statements that are issued and communicated by top-level management.
The effectiveness of the management system should be continually improved Document Control Individual paragraphs in this chapter describe how to ensure that all documents related to the management system are uniquely identified and created, approved, issued, and changed following documented procedures.
All official documents should be authorized and controlled. Documents should be regularly reviewed and updated if necessary. The review frequency depends on the document itself. Typical review cycles are between one and three years. Changes to documents should follow the same review process as for the development of initial documents.
Review of Requests, Tenders, and Contracts This chapter describes how to ensure that requirements of requests, tenders and contracts are well defined, reviewed, understood, and documented.
Changes in a contract should follow the same process as the initial contract. Subcontracting of Tests and Calibrations. This chapter describes how to ensure that tests and calibrations subcontracted to third parties are performed according to the same quality standards as if they were done in the subcontracting laboratory.
Purchasing Services and Supplies This chapter describes how to ensure that services and supplies delivered by third parties do not adversely impact the quality and effectiveness of laboratory operations.
Suppliers should be selected and formally evaluated to ensure that services and supplies are of adequate quality. Records of the selection and evaluation process should be maintained. The quality of incoming material should be verified against predefined specifications. Service to the Customer This chapter describes how to ensure that the laboratory continually meets customer requirements.
The laboratory should communicate with customers to clarify requests and get customer input. The laboratory should have a formal program to collect feedback from customers on an ongoing basis.
The laboratory should allow customers to audit the laboratory. Complaints This chapter describes how to ensure that any customer complaints are documented, evaluated, and adequately followed up.It is the wavelength in air that determines the basic length scale of measurements performed with laser interferometers.
This page is intended to serve as an aid to people doing interferometry who wish to check their own calculations of the refractive index against this NIST calculation.
1. Introduction. Physics is an experimental science, and as such the experimental basis for any physical theory is extremely important. The relationship between theory and experiments in modern science is a multi-edged sword.
In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them. When the variables are the values of experimental measurements they have uncertainties due to measurement limitations (e.g., .
Discussion. Because WBGT incorporates four environmental factors (air temperature, relative humidity, wind speed, and radiation [often sunlight]) that contribute to heat stress, it is the recommended workplace environmental heat metric.
