Non-discriminative tactile sensation is the tactile information that infants receive from their bodies in the arms of caregivers, helping infants to understand their bodies, establish body boundaries, and later integrate with proprioception to develop body schema, posture control, and voluntary movement. Discriminative tactile sensation is the basis for performing activities without visual assistance, such as fastening a button or taking something out of a pocket. Discriminative tactile sensation provides the basis for finger flexibility, bimanual coordination, perfection of body schema, etc. Note 2: The input of tactile sensation and proprioception in infancy develops body cognition, i.e. body schema. Maintaining posture in a quiet state is one of the important roles of the body schema, such as sitting for a long time in the classroom, children do not need additional conscious control can also maintain a sitting posture for a long time. 3.2 vestibular sensation sensory system that judges the relationship between the head and gravity, and adjusts posture and balance in time through accurate judgment of gravity 3.3 proprioception sensation produced by muscles, tendons, joints and other motor organs from inside the body when they are in different states (in motion or at rest) Note: In the caregiver's arms, infants feel very relaxed, but also need some control to help maintain the position in the arms, which creates proprioception. The infants from the initial lack of control of involuntary movement, to the accurate control of voluntary movement, are the result of the continuous development and maturation of proprioception. Proprioception is also an important basis for eating and oral language development. 3.4 visual integration visual system is the most important sensory channel for individuals to obtain information. Individuals perceive the outline, size, space, distance, color, light and shade of the surrounding environment and things through vision. The visual information received by the eyeball is processed by the visual central nerve, and the visual information is input into the visual cortex area of the brain and combined with other sensory information to analyze and recognize the features of the object 3.5 auditory integration when the auditory integration function is in operation, the sound wave is transmitted by the auditory receptors in the cochlea of the inner ear to the auditory center of the brainstem; the auditory center will conduct a preliminary analysis of the input auditory information and conduct a comprehensive analysis combining the sensory information such as vision, vestibular sensation, and proprioception, and then continue to judge the advanced auditory information in the auditory center, then the precise location, judgment and language understanding of sound content can be realized 3.6 accessible sensory integration training product component or part can be touched by any part prior to the reachable probe shaft shoulder described in the accessibility test for the sensory integration training product component or part [Source: GB 6675.2-2014, 3.1, modified] 3.7 hazardous sharp edge sensory integration training products may create accessible edges of unreasonable risk of injury during normal use and after testing of components for firmness [Source: GB 6675.2-2014, 3.24, modified] 3.8 hazardous sharp point sensory integration training products may create accessible points of unreasonable risk of injury during normal use and after testing of components for firmness [Source: GB 6675.2-2014, 3.25, modified] 3.9 removable component parts or components of sensory integration training product that can be disassembled without tools [Source: GB 6675.2-2014, 3.43, modified] 3.10 hazardous projection projection that, because of its material or configuration or both, may present a puncture hazard should a child step on or fall onto it. Note 1: Excluded from this definition are puncture hazards to the eyes and/or mouth, because of the impossibility of eliminating puncture hazards to those areas of the body by product design. Note 2: If the projection is on a sensory integration training product which topples over when pressure is applied to the end of the projection, it is unlikely to present a hazard. [Source: GB 6675.2-2014, 3.23, modified] 3.11 marble sphere made of hard material, such as glass, agate, marble or plastic, which is used in various children's games, generally as a playing piece or marker. Note: Marbles that do not contain a permanent package, such as pachinko, Mazes, and similar products do not release marbles during component fastness tests. [Source: GB 6675.2-2014, 3.30, modified] 3.12 large and bulky sensory integration training products sensory integration training products with a base projection area of more than 0.26m2 or a volume of more than 0.08m3 (excluding small appendages) or a mass greater than or equal to 4.5kg. Note: The base area for sensory integration training products having permanently attached legs is measured by calculating the area enclosed by straight lines connecting the outermost edge of each leg of the perimeter. 3.13 sensory integration training products intended to be entered by a child sensory integration training products made of fabric and/or polyester sheets or films intended for full or almost full entered by a child 3.14 surface flash flame spreads rapidly on the surface of the material, at the same time, the matrix structure of the material does not burn [Source: GB 6675.3-2014, 3.5, modified] 3.15 inflatable sensory integration training products sensory integration training products made of latex or plastic (such as soft polyvinyl chloride film) and filled with air, nitrogen or inert gases, including sensory integration training products that are inflated or intended to be inflated for a child to play with. Note: Latex refers to emulsified rubber that is generally easy to stretch, and is usually called emulsified rubber. 4 Classification Sensory integration training products can be classified into vestibular sensation training products, proprioception training products, tactile sensation training products, auditory integration training products, visual integration training products and comprehensive training products of the above training combinations, se
