DIN EN ISO

In order to implement the quality policy in the daily work, quality management systems are installed, covering quality planning, quality control, quality assurance and quality improvement. To ensure that the quality assurance system is in place and effective, external standards are used, for example the DIN EN ISO 9000 ff. standard system, commonly shortened to ISO 9000 (DIN is an acronym for Deutsches InstitutfiXr Normung, meaning German Industry Standard ). 

The best known international quality management standard seems to be the so-called DIN EN ISO 9001 ff. standard. ISO standards are agreements developed by technical committees. Since the members of these committees come from many countries, ISO standards tend to have very broad support. Conformance to that is said to guarantee that a company provides quality services and products. This standard was amended in 2000, so the current standard is called DIN EN ISO 9000 2000.

When using the unit-specific emission rate of the device with the highest emission (monitor 21, 14 d) in Table 17.6 as a basis for the total of POC (SERu = 2.6ggunit 1 h 1), a theoretical indoor air concentration of 0.3 igm"3 is obtained for the model room (DIN EN ISO 16000-9, 2006). The indoor air concentrations of all other devices are below this value by a factor of at least 10. The present results show that the POC emissions then result in a theoretical indoor... 

It is essential that proper sampling, storing and processing procedures of collected liquid media are followed to ensure the validity of subsequent bioassay results. In Germany, the DEV LI - DIN EN ISO 5667-16 (1998) guideline is applicable to all pT-scale bioassay protocols (DEV L30, L31, L33, L34, T3, T6).

Test batteries applicable for the pT-scale employ standardized test systems and procedures recognized by standardization organizations such as AFNOR, ASTM, DIN, EN, ISO, or OECD. The level of expertise required by personnel to ensure the proper application of pT-method bioassays must therefore comply with established norms. The necessary qualification will also depend on the test system being used.

In practice, the complete viscosity functions are often not specified for polymer melts. Instead, the melt flow rate (MFR) and/or the melt volumetric rate (MVR) is used. These parameters specify how much polymer mass and/or volume will flow out of a normalized flow channel within a specific period (e. g [cm3/10 min]) when subjected to stress (see DIN EN ISO 113, ASTM D1238). Low-viscosity, easily flowing polymers have high MFR or MVI values, while high viscosity/slow flowing polymers have low MFR or MVI values. These values are listed e.g. in plastics databases such as CAMPUS [3],... 

DIN EN ISO 8044 defines wear as the progressive loss of material from the surface of a solid body due to mechanical causes, i. e., contact with solid, liquid, or gaseous bodies and relative motion. Wear is manifested in the presence of loosened particles (wear particles) and in the change in material and shape of the surface layer. Thermal, physical, and chemical processes are activated in the case of most wear processes (triboreactions). Wear is fundamentally caused by mechanically transferred energy.
