1 Scope
This Standard specifies the general process and basic requirements for the use of
scenario simulation to identify consumer product safety hazards, simulation scenario
design, execution evaluation, data collection and result analysis.
This Standard is applicable to consumer product safety related parties to carry out
hazard identification during the design, production, and use (including maintenance)
stages of consumer products.

--- The possibility of a certain hazard occurring in real life;
--- The severity of a hazard in real life.
4) Interview outline, which usually includes:
--- Participants' understanding of the task;
--- Participants' thoughts and feelings during the execution of the evaluation
task;
--- The hazards that the participant thinks that he or she may occur in the
evaluation task;
--- How do participants take measures to avoid possible hazards;
--- What other hazards do the participants think are not found in the evaluation
task, but may occur in real life;
--- Participants' suggestions and ideas on the evaluation.
c) The requirements for participant selection are as follows:
6.2.2 Perform evaluation
Participants shall complete the evaluation according to the task design, and the
specific process is shown in A.3.2.
7 Data Collection and Result Analysis
