This European Standard specifies a method for testing the resistance of domestic articles made from ceramic, glass, glass ceramic, vitreous enamel, metal and plastics under the combined chemical, thermal and mechanical stresses of mechanical dishwashing in domestic dishwashers. It specifies a reference test method for domestic dishwashing only. It does not define the number of dishwashing cycles which any given product shall withstand.

This document specifies the conditions for the visual inspection of domestic articles made from ceramic, glass, glass ceramic, decorated glass, vitreous enamel, coatings, rubber, silicones, metal, and plastics after testing its dishwashing resistance according to the procedures described in the relevant parts of the EN 12875 series.

This document specifies a method [1] for the quantitative determination of saxitoxin (STX), decarbamoyl saxitoxin (dcSTX), neosaxitoxin (NEO), decarbamoyl neosaxitoxin (dcNEO), gonyautoxin 1 and 4 (GTX1,4; sum of isomers), gonyautoxin 2 and 3 (GTX2,3; sum of isomers), gonyautoxin 5 (GTX5 also called B1), gonyautoxin 6 (GTX6 also called B2), decarbamoyl gonyautoxin 2 and 3 (dcGTX2,3; sum of isomers), N sulfocarbamoyl gonyautoxin 2 and 3 (C1,2; sum of isomers) and N-sulfocarbamoyl gonyautoxin 1 and 4 (C3,4; sum of isomers) in (raw) mussels, oysters, scallops and clams. Laboratory experience has shown that this document can also be applied to other marine invertebrates [2], [3] and processed products of those species, however, no complete interlaboratory validation study according to ISO 5725 2:1994 has been carried out so far. The method described was validated in an interlaboratory study [4], [5] and was also verified in a European Union Reference Laboratory for Marine Biotoxins (EURLMB)-performance test aiming the total toxicity of the samples [6]. Toxins which were not available in the first interlaboratory study [4], [5] as dcGTX2,3 and dcNEO were validated in two additional interlaboratory studies [7], [8]. The lowest validated levels [4], [5], [8], are given in µg toxin (free base)/kg shellfish tissue and also as µmol/kg shellfish tissue and are listed in Table 1. [Table 1] A quantitative determination of GTX6 was not included in the first interlaboratory study but several laboratories detected this toxin directly after solid phase extraction with ion-exchange (SPE-COOH) clean-up and reported a mass concentration of 30 µg/kg or higher in certain samples. For that reason, the present method is applicable to quantify GTX6 directly, depending on the availability of the standard substance. Whenever GTX6 standard is not commercially available, it is possible to determine GTX6 after hydrolysis of Fraction 2 of the SPE-COOH clean-up, described in 6.4, as NEO. The indirect quantification of GTX6 was validated in two additional interlaboratory studies [7], [8]. A study to compare direct and indirect GTX6 quantification was conducted at the EURLMB [16]. A quantitative determination of C3,4 was included in the first interlaboratory study. The present method is applicable to quantify C3,4 directly, depending on the availability of the standard substance. If no standard substances are available, C3,4 can only be quantified as GTX1,4 if the same hydrolysis protocol used for GTX6 (6.4) is applied to Fraction 1 of the SPE-COOH clean-up [10]. A study to compare direct and indirect C3,4 quantification was conducted at the EURLMB [16].

1.1 This document specifies safety and hygiene requirements for the design and manufacture of pizza dough sheeters which: a) are intended to be used: 1) for producing mainly pizza dough bases in shops and craft activities (i.e. pizzerias, takeaway pizza shops, craft bakeries and/or pastries, catering facilities, etc.); 2) for flattening and enlarging pieces of dough; 3) only for professional use; 4) by one operator at a time; 5) as standalone table-top machines only; 6) only with manual feeding of the pieces of pizza dough by gravity; 7) only with manual unloading of the flattened and enlarged pieces of pizza dough; b) are fitted with: 1) at most two pairs of flattening rollers, the rollers of a pair having the same diameter and the same length; 2) flattening rollers having: i. diameter ≤ 60 mm; ii. fixed direction of the rotation such as to move the pizza dough from top to bottom; iii. motor(s) for the rotation of the flattening rollers which transmit a power ≤ 0,50 kW to each pair of rollers 1.2 The following relevant hazards are not covered by this document: - hazards arising from the use of an automatic loading and/or unloading system; - hazards due to packaging, handling and transport; - hazards due to ambiguous and/or not easily understandable information needed to control the machine. This document does not deal with any specific requirement on noise emitted from pizza dough sheeters as the generated noise does not cause a relevant hazard. The significant hazards covered by this document are described in Annex A. 1.3 The following machines are excluded from the scope of this document: - domestic (household) appliances; - machines with automatic feeding of the pizza dough pieces and/or unloading of the pizza bases; - machines with feeding of the lumps other than by gravity; - machines to process other products than pizza dough; - bagel machines; - dough sheeters (see EN 1674:2015); - moulders (see EN 12041:2014); - sheeters for pasta dough processing; - experimental and testing machines under development by the manufacturer. 1.4 This document is not applicable to machines which are manufactured before the date of publication of this European Standard.

This document specifies a procedure for obtaining a migration water to determine odour, flavour, colour and turbidity for products made from organic materials intended to come in contact with water for human consumption (drinking water) and used in piping and storage systems. Such products include pipes, tanks, reservoirs, fittings, ancillaries and their coatings both for site applied and factory-made products. This document is applicable to products to be used under various conditions for the transport, storage and distribution of water intended for human consumption and raw water used for the manufacture of water intended for human consumption. This document specifies a test method comprising a set of procedures. The use might be dependent on the relevant national regulations and/or the system or product standards.
