National standards - control

Specifications, Standards, Quality Control, and Health and Safety Factors. Formerly, there was an Insulation Board Institute representing the insulation board industry, but the decline in the market and number of producers has led to its demise. Currently (ca 1997), the industry is represented by the American Hardboard Association (AHA). Specifications and standards are found in American National Standards Institute (ANSI) standard for CellulosicFiberboard (7). The standard includes descriptions of the various types and classes of ftberboard, as well as requirements for physical and dimensional stabiUty properties. QuaUty control tests are limited to a few basic strength and stabiUty tests, including bending strength, bond strength, and moisture resistance. 

In the world of documents there are two categories those that are controlled and those that are not controlled. A controlled document is one where requirements have been specified for its development, approval, issue, revision, distribution, maintenance, use, storage, security, obsolescence, or disposal. You do not need to exercise control over each of these elements for a document to be designated a controlled document. Controlling documents may be limited to controlling their revision. On the other hand, you cannot control the revision of national standards but you can control their use, their storage, their obsolescence, etc. Even memoranda can become controlled documents if you impose a security classification upon them. 

This requirement is similar to that stated in clause 4.11.2 of the standard and addressed later in this chapter. The checks and rechecks required to prove that the software is capable of verifying the acceptability of product are a means of calibrating test software. However, test software does not wear or drift with age or use and so cannot be calibrated against a standard traceable to national standards. To control test software you need to consider what it is that you need to control. As a minimum you should control its use, modification, location (in terms of where it is installed), replication, and disposal. Requirements for other controls are covered in clause 4.11.2 of the standard, where they can be applied to test software. 

However, the various national standards organizations, power boiler manufacturers associations and research institutes (such as the Electric Power Research Institute in the United States) do offer guidelines and recommendations for good waterside control and the avoidance (or at least the minimization) of the more exotic forms of waterside damage.

The standardized testing methods play a central role in the EU policy on chemicals control and they are referred to in many other pieces of EU legislation (e.g., those related to dangerous preparations, pesticides, cosmetics, and biocides also refer to these methods). The methods are based on those recognized and recommended by competent international bodies, in particular OECD (Section 2.2). When such methods were not available, national standards or scientific consensus methods have been adopted. 

The ITS is an artifact scale, designed to relate temperature measurements made with practicable instruments as closely as possible to the thermodynamic scale. The scale is established and controlled by the International Committee of Weights and Measures (BIPM) through its Consultative Committee on Thermometry, which was established in 1937. The BIPM itself is established to maintain and implement the Treaty of the Meter, to which most nations of the wodd subscribe thus the ITS has not only scientific but legal status in most nations. Within nations, the Temperature Scale is maintained by national standards establishments, eg, in the United States the National Institute for Standards and Technology (NIST), in England the National Physical Laboratory (NPL), and in Germany the Physikalisch-Technische Bundesanstalt (PTB). 

In Canada, the federal mandate for food control rests with four departments Health Canada, Agriculture and Agri-Eood Canada, Department of Fisheries and Oceans, and Industry Canada. A cooperative relationship exists among departments with the ultimate goal of creating a harmonized and streamlined national food control system. All four departments ensure the application of food safety standards in their areas of responsibility to prevent or eliminate human health and safety threats created through chemical, biological, physical, or other hazards. 

For the control/monitoring instrumentation, regulating devices, and any associated electrical equipment, predelivery testing and calibration is normally the responsibility of the instrument/equipment manufacturer and should be carried out to approved written procedures using calibration test equipment that is traceable back to agreed-upon national standards. The test equipment must have precision, accuracy, and repeatability that are higher than that of the instrument being calibrated. 

Through an agreement in Vienna in 1991, CEN and ISO have cooperated in the following way. Since both technical committees targeted standardization of cleanroom specifications they were merged to form the committee ISO/TC 209, Cleanrooms and Associated Controlled Environments. Draft standards are submitted to ISO and CEN bodies at the same time. If approved by CEN, the standard will become a mandatory national standard of all the European states and existing conflicting requirements have to be withdrawn. If approved by ISO, the member states (outside Europe) can adopt the standard if they want to do so.

Certainly any organization that requires traceability to national standards ought to focus on whether the measurements made by the organization subject to the trace-ability requirement are sufficiently accurate for their intended purpose and not simply on whether NBS calibration certificate(s) is on file. Without a valid uncertainty statement and evidence that the measurement process remains in a state of statistical control, no one can deter-... 

The national standards for the various fields in which gas analysis is of importance are provided by BAM and UBA. PTB s contribution is the type approval of gas analytical measuring instruments whose metrological control is required by the legal regulations. 

Gas analytical instruments for vehicle exhaust emission surveillance, evidential breath alcohol analysis in road traffic and calorific value determination of fuel gases are subject to legal control and require type approval and initial and subsequent verification. The national standards required in this part of gas analysis are provided by BAM. PTB uses in-house standards prepared by dynamic blending to ensure traceability of its type approval...
