Introduction This document establishes minimum safety requirements and specifies appropriate test methods for children’s cutlery and feeding utensils. Children’s cutlery and feeding utensils are used by either the carer to feed the child or by the child itself, from the average age of weaning (6 months) to 3 years of age. Children over three years of age increasingly use cutlery and utensils designed for adults. Accordingly, this document addresses the potential hazard(s) arising from the use of cutlery and feeding utensils designed for the use of children aged up to 3 years, with or without parental supervision. However, it is stressed that this document cannot eliminate all possible risks to young children up to 3 years of age using such products and that parental or guardian control is of paramount importance. It is essential that the manufacturer gives all warnings and instructions specified in this document clearly, to allow the consumer to ensure the product is used correctly and safely. A significant choking hazard can arise if components of cutlery or feeding utensils become separated during use. This hazard is addressed in this document by the inclusion of security tests. This document also addresses the potential hazard(s) arising from the release of one or more substances, in quantities which could be considered detrimental to health, from the material(s), used in the construction of cutlery and feeding utensils. It is noted that all plastic components of cutlery and feeding utensils are regulated by the Commission Directive 2002/72/EC [1] relating to plastics materials and articles intended to come into contact with foodstuff. It is further noted that Council Directive 89/109/EEC [2] approximates laws of the Member States relating to materials and articles intended to come into contact with foodstuff. Where applicable, Council Directive 82/711/EEC [3] and related amendments (93/8/EEC and 97/48/EC) laying down the basic rules necessary for testing migration of the constituents of plastic materials and articles intended to come into contact with foodstuff has been applied as has Council Directive 85/572/EEC [4] relating to the list of simulants to be used for testing migration of constituents of plastic materials and articles intended to come into contact with foodstuff. It is also noted that the European Parliament and Council Directive 94/27/EC [5] regulates nickel release permitted from jewellery and items in contact with the skin. It is noted that Council Directive 84/500/EEC [6] relates to ceramic articles intended to come into contact with foodstuff. Commission Decision 99/815/EC [7] prohibits the placing on the market of toys and childcare articles made of soft PVC (containing one or more of six specific phthalate plasticisers) and which are intended to be placed in the mouth by children under three years of age. It is recommended that manufacturers and suppliers operate to EN ISO 9001 [8] standard for quality management systems.

Drain excess water before allowing the samples to cool to room temperature in a desiccator for (24 ± 1) h prior to testing. Use new samples, preferably from the same batch, for each test unless otherwise stated (i.e. samples used in one test shall not be used in another test). 6.2 Mechanical tests 6.2.1 Sharp points test Test in accordance with EN 71-1. 6.2.2 Sharp edges test Test in accordance with EN 71-1. 6.2.3 Tensile test The tensile force shall be applied to one component of the sample whilst another component is firmly held. A pre-load of (5 ± 2) N shall be applied to align the specimen and then the force shall be increased to (90 ± 5) N at a cross head speed of (10 ± 5) mm/min and maintained at that level for (10 ± 1) s. Clamps or other devices shall hold the components securely during the test without giving rise to damage which might affect the test result. Any results where such damage occurs shall be disregarded. Tests shall be carried out along the major axis and at the right angles to the major axis. Every possible combination of pairs of components shall be tested. SIST EN 14372:2005
EN 14372:2004 (E) 13 6.2.4 Tear resistance test The components to be tested shall be separated or if necessary, cut from any other components. Place the component to be tested on a cutting board of at least 10 mm thickness and (70 ± 5) Shore D hardness. Place the tip of the indentor, the shape and dimensions of which are given in Figure 5, in the approximate centre of the largest surface of the component to be tested. At a crosshead speed of (10 ± 5) mm/min apply a force of (200 ± 10) N for (1 ± 0,5) s. If the indentor punctures the component carry out a tensile test in accordance with 6.2.3. For the component suitable fixing devices shall be used to hold opposite ends of the component securely, so that the puncture produced by the indentor is at 90 ° to the axis of tensile force.

Conditions which simulate contact with stomach acid shall be used. The concentrations of the soluble elements are described quantitatively. 6.3.1.2 Apparatus, reagents, procedure and determination Tests shall be carried out according to EN 71-3. 6.3.2 Determination of phthalate content 6.3.2.1 Principle The aim of the method is primarily to extract, identify and quantify monomeric phthalates (with wider application to other types of plasticisers) contained in PVC samples. The extraction method uses Soxhlet extraction apparatus with diethyl ether. The total diethyl ether extractable plasticiser content is calculated by weight with Gas Chromatography-Mass Spectroscopy (GC-MS) detection to identify and quantify individual phthalates.

Weigh accurately (2 ± 0,2) g of the pieces into a Soxhlet thimble and add cotton wool to the top of the thimble. Add approximately (50 ± 10) ml of diethyl ether into the flask. Reflux gently for 6 h ± 30 min. Allow sufficient time for the diethyl ether to cool. Completely evaporate the diethyl ether by means of a steam bath. Place the flask in an oven at (105 ± 5) °C for (30 ± 5) min. Allow to cool in a desiccator and weigh. Repeat the drying and cooling cycles until the difference between two consecutive weighings are not more than 0,0005 g. A blank solution
