In practical applications, EN 71-1, EN 71-2, and EN 71-3 constitute the most fundamental testing requirements.

EN 71-1 is the part of the EN 71 standard concerning the safety of toys in relation to their physical and mechanical properties. Its full title is "Safety of toys - Part 1: Mechanical and physical properties." This section specifies the safety technical requirements for the mechanical and physical properties of toys intended for use by children of different age groups, from newborns up to 14 years of age. It also includes requirements for packaging, marking, and instructions for use. Its core objective is to ensure that toys, under normal use and foreseeable reasonable abuse, do not cause physical harm to children due to design or manufacturing defects.

EN 71-2 is the part of the EN 71 standard specifically addressing the flammability of toys. Its full title is "Safety of toys - Part 2: Flammability." This section specifies the flammability requirements for materials used in toys, aiming to reduce the risk of fire originating from toys and the associated burn hazards to children. EN 71-2 clearly defines the categories of highly flammable materials that are prohibited in all toys and establishes corresponding limits for the speed of flame spread or burning time for different types of toys.

EN 71-3 is the part of the EN 71 standard that sets limits for the migration of certain elements from toy materials. Its full title is "Safety of toys - Part 3: Migration of certain elements." This section specifies the maximum allowable migration limits for certain elements (primarily 19 migratable heavy metal elements) from accessible parts of toys or materials. Its aim is to reduce the risk of children's exposure to these harmful substances through mouthing contact, skin contact, or inhalation.

EN 71-3 - Scope of Testing:

•All accessible materials on a single toy must be tested.

•Packaging materials that form part of the toy or are intended to be kept for play are subject to testing.

•Materials that are not small parts and are made of metal, glass, or ceramics are exempt from testing.

•Toy materials weighing less than 10 mg are exempt from testing.
