“GB 6675 National safety technical code for toys" is revised as: "GB 6675.4-2014 Safety of toys - Part 4: Migration of certain elements (ISO 8124-3:2010, MOD)" in the normative references.
II. Subclause 4.2.5
"The manufacturer of child restraint system shall declare in writing that the toxicity of the materials used for manufacturing child restraint system and the child susceptibility to the materials are consistent with GB 6675. This subclause is not applicable to the child restraint system of Group II and Group III." in the original standard is revised as "The manufacturer of child restraint system shall declare in writing that the limit of migratory element in the materials used for manufacturing child restraint system that are accessible to children shall meet the requirements of GB 6675.4-2014. This subclause is not applicable to the child restraint system of Group II and Group III. "
III. Subclause 4.2.6
"The manufacturer of child restraint system shall declare in writing that the combustion characteristics of the materials used for manufacturing child restraint system shall meet the requirements of GB 8410." in the original standard is revised as "The manufacturer of child restraint system shall declare in writing that for non-built-in child restraint systems, when the materials used for manufacturing child restraint system are tested according to the method specified in GB 6675.3-2014, 5.4, the flame spreading speed shall not exceed 30mm/s, or the flame shall extinguish by itself before reaching the second marking line; for built-in child restraint systems, the combustion characteristics of the materials used for manufacturing child restraint system shall meet the requirements of GB 8410."
IV. Subclause 5.1.4.1.10.1
"ISOFIX child restraint systems of Class A and Class B shall be tested according to the requirements of 5.1.4.1.10.1.1 and 5.1.4.1.10.1.2." in the original standard is revised as "ISOFIX child restraint systems of Class A, Class B and Class B1 shall be tested according to the requirements of 5.1.4.1.10.1.1 and 5.1.4.1.10.1.2."
?
V. Subclause 6.3.1
"If the initial values of impact deformation and deceleration peak are required, the test seat cushion shall be calibrated after every 50 dynamic tests or at least every month (whichever comes first). If the test equipment is used frequently, calibration shall be carried out before each test." in the original standard is revised as "In order to obtain the initial values of impact deceleration peak, the new test seat cushion shall be calibrated after every 50 dynamic tests or at least every month (whichever comes first)."
VI. Subclause 6.3.3
"The deviation between the recorded peak value and the initial peak value shall not exceed 15%." in the original standard is revised as "The impact deceleration peak value recorded in the first calibration shall be 18±3g, and the deviation between the impact deceleration peak value recorded in the subsequent calibration and that recorded in the first calibration shall not be greater than 15%."
VII. Subclause 8.4
"For rearward-facing child restraint system, ……The label shall indicate the following information in both Chinese and English: …… (see Figure 11)." in the original standard is revised as "For rearward-facing child restraint system, ……The label shall indicate the following minimum information: …… see Figure 11)."
Wherein, Figure 11 is revised as follows:
