What is the Amazon 16 CFR 1700.20 Test Report?

16 CFR 1700.20is a child-resistant packaging testing standard established by the U.S. Consumer Product Safety Commission (CPSC). It is designed to evaluate a package’s ability to prevent children of specific age groups from opening it, while ensuring that adults can use it normally. Below are the key points of this test:

Purpose of the Test

The test verifies that the packaging design can effectively prevent children aged 42–51 monthsfrom opening it (such as medicine, button batteries, and chemical containers), thereby reducing the risk of accidental ingestion. At the same time, it ensures that adults, especially those aged 50–70, can open and close the package smoothly.

Test Subjects Requirements

Children Group

①　Age:42–51 months, divided as follows:

42–44 months: 30%

45–48 months: 40%

49–51 months: 30%

②　Sample Size:At least 200 children, with gender ratio deviation ≤10%

③　Restrictions:No tools or external assistance allowed

Adult Group

①　Age:50–70 years, divided as follows:

50–54 years: 25%

55–59 years: 25%

60–70 years: 50%

②　Sample Size:At least 100 adults, must understand packaging instructions and operate independently

③　Gender Ratio:Some tests require 70% female participants

Test Methods and Acceptance Criteria

Children Testing Procedure

1. First Attempt:Free attempt to open the package within 5 minutes.

2. Second Attempt:After a short break, another 5-minute attempt.

Passing Standard:≥80% of children fail to open the package in both attempts.

Adult Testing Procedure

1. First Opening:Open the package within 90 seconds.

2. Repeated Operation:Open and re-close the package within 5 minutes.

Passing Standard:≥90% of adults can complete the operation successfully.

Packaging Design Requirements

①　Materials & Structure:High-strength materials and complex opening mechanisms (e.g., double-layer locks, push-and-twist designs).

②　Warning Labels:Clear warning labels indicating child safety risks.

③　Applicable Products:Items requiring child resistance, such as button batteries, medicines, and chemicals.

Test Duration and Samples

Duration:Approximately 3–4 weeks.

Sample Quantity:10 newly manufactured packages, covering different sizes/capacities.

Regulatory Background

This standard originates from the U.S. “Reese’s Law”, which mandates that products like button batteries pass child-resistant tests to prevent accidental ingestion by children.

Certification Process

1. Submit application form and product informationfor evaluation.

2. Provide test samples.

3. Laboratory conducts the test and generates a report.

4. Upon passing, CR certification (Child-Resistant Packaging)is issued.

> Note: The test must be conducted by a CPSC-accredited laboratory(e.g., ANAB-certified labs).
