- Who's Accredited
Guidelines for testing and calibration laboratories and their customers on the decision and reporting of compliance or non-compliance with specified requirements.
Information on how to define the scope of accreditation and identify some criteria and ways of assessing the scope to provide practical guidance for an effective and harmonized application of relevant international standards.
Describes how the concept of uncertainty of measurement in testing has changed recently and how it should be introduced with regard to current understanding. The main goal is harmonization of application between different disciplines, industry sectors, and economies.
Addresses the estimation of uncertainty of measurement and its expression on calibration certificates of accredited laboratories.
Provides service personnel with a method to identify and quantify the uncertainty components for scale and balance calibrations in both field and laboratory environments.
Detailed guidance for evaluation and expression of uncertainty in quantitative chemical analysis, based on the approach taken in the ISO Guide to the Expression of Uncertainty in Measurement (GUM).
Gives laboratories guidance on how to determine calibration intervals. Identifies and describes methods available for evaluation of calibration intervals.
Developed to ensure a more uniform approach to use of accreditation symbols and the manner in which a laboratory may refer to its accreditation status and the ILAC MRA. Only statements that use the term "shall" are requirements (v. guidelines).
Guidance on establishing and managing a proficiency testing/ILC program. Applicable to all types of laboratories, general in nature, and easy to read and understand, with useful examples.
NIST Recommended Practice Guide created to a fill a gap in the metrology literature. Assists the working metrologist or calibration technician by describing the types of stopwatches and timers that require calibration, specifications and tolerances of these devices, methods used to calibrate them, and estimated measurement uncertainties for each calibration method.
Good for not only calibration laboratories but also for the users of infrared guns and cameras.
