This document specifies a method for the detection of Salmonella spp. in soil improvers and growing media. It is applicable to material in solid form (including pre-shaped growing media) and liquid form.
This document is applicable to fertilizing product blends, where a blend is a mix of two or more fertilizing products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media comprise the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If soil improvers and/or growing media do not comprise the highest percentage in the blend, the European Standard for the highest percentage in the blend applies. In case a blend is composed of fertilising products in equal quantity, the user of the standard decides which standard to apply.
Most of the Salmonella serovars are detected with the method described in this document. For the detection of some specific Salmonella serovars (e.g. Salmonella Typhi and Salmonella Paratyphi), additional cultivation steps can be necessary.
NOTE 1 A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (Annex C).

Strains of E. coli which do not grow at 44 °C ± 1 °C and, in particular, those that are β-D-glucuronidase-negative, such as E. coli O157, will not be detected. Some strains of Shigella spp. and Salmonella spp. within the family Enterobacteriaceae can also show β-D-glucuronidase activity at 44 °C ± 1 °C.
NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (Annex C).

This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities.
This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed.
This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13).
Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail.
Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned.
The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1.
A list of equivalent terms in several European languages is given in Annex A.

This document specifies requirements and provides recommendations for the design and installation of connections (bonds) between various electrically conductive elements in buildings and other structures, during their construction or refurbishment, in which information or telecommunications technology equipment is intended to be installed in order to:
a) minimise the d.c. and a.c. potential differences in order to reduce the risk of malfunction of that equipment and interconnecting cabling due to electromagnetic disturbance;
b) provide the telecommunications installation with a reliable signal reference – which may improve immunity from electromagnetic interference (EMI).
The requirements of this European Standard are applicable to the buildings and other structures within premises addressed by EN 50174-2 (e.g. residential, office, industrial and data centres) but information given in this European Standard may be of assistance for other types of buildings and structures.
NOTE Telecommunications centres (operator buildings) are addressed by ETSI/EN 300 253.
This European Standard does not apply to power supply distribution of voltages over AC 1 000 V.
Electromagnetic compatibility (EMC) requirements and safety requirements for power supply installation are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting the requirements of these standards and regulations.

This document specifies methods for the chemical analysis of zirconium oxide powders used as the raw material for fine ceramics.
It stipulates the determination methods of the zirconium, aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium, titanium and yttrium contents in zirconium oxide powders for fine ceramics. The test sample is decomposed by acid pressure decomposition or alkali fusion. Contents of zirconium and yttrium are determined by using either a precipitation and gravimetric method or an inductively coupled plasma–optical emission spectrometry (ICP–OES) method. Contents of aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium and titanium are determined by using an ICP–OES method.
