Automotive fuels - LPG - Requirements and test methods

This European Standard specifies requirements and test methods for marketed and delivered automotive LPG (Liquefied Petroleum Gas). It is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG. NOTE: For the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction. WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health which arises through inhalation of excessive amounts of LPG. LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. All procedures should be conducted away from sources of ignition such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be performed as far as practicable under an electrically-safe ventilation hood. LPG in liquid form can cause cold burns to the skin. Protective clothing such as gloves and goggles should be worn if contact with the skin is likely to occur. Unnecessary inhalation of LPG vapour should be avoided. The operator should not be exposed to atmospheres containing more than 1 800 mg/m3 over an 8 h time-weighted average (TWA) reference period, or more than 2 250 mg/m3 over a short term, 10 min reference period. One of the tests described in this European Standard involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to.


Safety of toys – Part 1 : Mechanical and physical properties

This European Standard specifies requirements and methods of tests for mechanical and physical properties of toys. This European Standard applies to toys for children, toys being any product or material designed or intended, whether or not exclusively, for use in play by children of less than 14 years. It refers to new toys taking into account the period of foreseeable and normal use, and that the toys are used as intended or in a foreseeable way, bearing in mind the behaviour of children. It includes specific requirements for toys intended for children under 36 months, children under 18 months and for children who are too young to sit up unaided. According to Directive 2009/48/EC “intended for use by” means that a parent or supervisor shall reasonably be able to assume by virtue of the functions, dimensions and characteristics of a toy that it is intended for use by children of the stated age group. Therefore, for the purpose of this European Standard, e.g. soft-filled toys with simple features intended for holding and cuddling are considered as toys intended for children under 36 months. NOTE Information relating to the age grading of toys and, in particular, which toys are intended for children under 36 months and which toys are not, can be found in CEN Report CR 14379, the Consumer Product Safety Commission (CPSC) Age determination guidelines, CEN/CENELEC Guide 11 and the European Commission’s Guidance Documents. This European Standard also specifies requirements for packaging, marking and labelling. This European Standard does not cover musical instruments, sports equipment or similar items but does include their toy counterparts. This European Standard does not apply to the following toys:  playground equipment intended for public use;  automatic playing machines, whether coin operated or not, intended for public use;  toy vehicles equipped with combustion engines (see A.2);  toy steam engines;  slings and catapults. Items that are propelled into free flight by a child releasing an elastic band (e.g. aeroplanes and rockets) are considered as catapults (see 5th indent above). This European Standard does not cover electrical safety aspects of toys. These are covered by EN 62115. Furthermore, it does not cover the following items which, for the purpose of this European Standard, are not considered as toys:  decorative objects for festivities and celebrations;  products for collectors, provided that the product or its packaging bears a visible and legible indication that it is intended for collectors of 14 years of age and above. Examples of this category are:  detailed and faithful scale models (see A.2);  kits for the assembly of detailed scale models; NL EN 71-1:2014 EN 71-1:2011 (E) 10  folk dolls and decorative dolls and other similar articles;  historical replicas of toys;  reproductions of real fire arms;  sports equipment including roller skates, inline skates, and skateboards intended for children with a body mass of more than 20 kg;  bicycles with a maximum saddle height of more than 435 mm, measured as the vertical distance from the ground to the top of the seat surface, with the seat in a horizontal position and with the seat pillar set to the minimum insertion mark;  scooters and other means of transport designed for sport or which are intended to be used for travel on public roads or public pathways;  electrically driven vehicles which are intended to be used for travel on public roads, public pathways, or the pavement thereof;  aquatic equipment intended to be used in deep water, and swimming learning devices for children, such as swim seats and swimming aids;  puzzles with more than 500 pieces;  guns and pistols using compressed gas, with the exception of water guns and water pistols;  bows for archery over 120 cm long;  fireworks, including percussion caps which are not specifically designed for toys;  products and games using sharp-pointed missiles, such as sets of darts with metallic points;  functional educational products, such as electric ovens, irons or other functional products, as defined in 2009/48/EC, operated at a nominal voltage exceeding 24 V which are sold exclusively for teaching purposes under adult supervision;  products intended for use for educational purposes in schools and other pedagogical contexts under the surveillance of an adult instructor, such as science equipment;  electronic equipment, such as personal computers and game consoles, used to access interactive software and their associated peripherals, unless the electronic equipment or the associated peripherals are specifically designed for and targeted at children and have a play value on their own, such as specially designed personal computers, key boards, joy sticks or steering wheels;  interactive software, intended for leisure and entertainment, such as computer games, and their storage media, such as CDs;  babies' soothers;  child-appealing luminaires;  electrical transformers for toys;  fashion accessories for children which are not for use in play (see A.2); NL EN 71-1:2014 EN 71-1:2011 (E) 11  personal protective equipment, including flotation aids such as arm bands and swim seats (see A.23); and swimming goggles, sunglasses and other eye protectors as well as bicycle and skateboard helmets (see A.19).
