DIN Standard

German Standards, Beuth, Germany, English translation of more than 4750 popular DIN Standards plus 1500 DIN-EN, DIN-EC and DIN-ISO Standards. 

The state of the art in 1987 was published in Survey of standards, technical rules and regulations in the area of corrosion, corrosion testing and corrosion protection, together with the most important DIN standards and some other regulations in the DIN 219 [71]. A commentary on these standards has also appeared [72]. 

This parameter was introduced in the ISO/EN and DIN standard quoted earlier. In order to have good polymer separation efficiency, the following criterion has to be met ... 

Factory tests establish the pressure head, power, efficiency and NPSH over the complete flow range the pump can deliver running at design speed. British Standard, DIN standard or ANSI standard codes or national variations from such main codes lay down the manner of test procedure, and a minimum requirement is quite often defined by industry codes such as API 610. This is not the place to discuss instrument accuracy, as the codes lay down the limits possible from conventional instruments. There are two main classes of test the commercial requirements normally possible in the maker s test plant and high-accuracy tests that are only possible by using substandard instruments and very sophisticated techniques. 

Glasl [149] reported the foaming properties of several alcohol sulfates and alcohol ether sulfates using the perforated disk method as described in the DIN standard 53902. All values were obtained at 0.28 g/L surfactant concentration, both in distilled water and in water of 16°dH hardness at 20, 40, and 60°C. The results are shown in Figs. 15-17.

There is no continuity in sizing of chemical equipment. There are discrete changes in capacities of chemical equipment of all kinds, either due to state and international standards or due to internal standards of individual manufacturers of chemical equipment. For instance, according to DIN standards, the volumes of glass-lined reactors increase in... 

It has become fairly common to adopt the manufacture of combinations of internal reference electrode and its inner electrolyte such that the (inner) potential at the glass electrode lead matches the (outer) potential at the external reference electrode if the glass electrode has been placed in an aqueous solution of pH 7. In fact, each pH glass electrode (single or combined) has its own iso-pH value or isotherm intersection point ideally it equals 0 mV at pH 7 0.5 according to a DIN standard, as is shown in Fig. 2.11 the asymmetry potential can be easily eliminated by calibration with a pH 7.00 0.02 (at 25° C) buffer solution. 

If the inner reference of the electrode is such that the iso-pH value (isotherm intersection point) lies at pH = 7 0.5 (according to a DIN standard), which may agree with the Ege vs. pH plot in Fig. 2.11, then the overall potential of this...

The Mooney arrangement of a bob with a conical base is an attractive design as it is relatively easy to fill and uses the base area to enhance the measurement sensitivity. However the cone angle must be such that the shear rates in both the cone and plate and concentric cylinder sections are the same. This means that the gap between the cylinders must be very slightly larger than the gap at the edge of the cone and plate if a constant shear rate is required. Unfortunately the DIN standard bob is poor in this respect. 

Because of reasons mentioned above the preparation, the dimensions, and the pretreatment of the test specimen have been standardized (DIN standard or ASTM standard). The important characteristic values of technical polymers are listed in databases (Campus, Polymat). 

National standards are primarily DIN standards, particularly those relating to the area of vacuum technology in the DIN Standards Committee on Mechanical Engineering (NAM). International standards and recommendations are drawn up and issued... 

The content of the documents drawn up by the international organizations in a) to c), with German participation (also by LEYBOLD), has been extensively incorporated into DIN standards, as reflected in designations such as DIN/ISO orDIN/EN.

A prerequisite for any quality control is the definition of how the characteristics of a specific raw material, an intermediate product or a final product of a manufacturing process should be described. This means that all characteristics for every single product have to be defined in adequate standards and specifications so that the results obtained can be compared with these data. Numerous standards and specifications have been established in more or less official specification collections, for example pharmacopoeias, the aforementioned ISO or DIN standards, standards of the Essential Oil Association or the American Spice Trade Organization (ASTA).

DUO tests are particularly suitable for this, i.e. tests in which pairs of samples are compared. These are tests such as the Paired Comparison Test (DIN Standard 10 954 [5], ISO Standard 5495 [6]) and the Comparison Test which does not involve a direct question about the difference. [Although it is called a Comparison Test in English, it actually deals with differences]... 

All analysis and measurement procedures cited in the AbwV and AbwAG are standardised methods, either by DIN, ISO or CEN. Development and standardisation of biotests for emission control are carried out by national working groups on biotests (DIN), resulting in DIN standard protocols since 1976. Representatives of federal government, the Lander, industry and universities are usually present in the national working groups.
