16 CFR Part 1616——Standard for the Flammability of Children's Sleepwear:Sizes 7 through 14(FF5-74)

Core Objective: 

To require children's sleepwear to self-extinguish after being removed from an open flame, rather than continuing to burn.

Scope of application and key definitions:

Target Audience:Suitable for children’s pajamas in sizes 7 to 14.

What are children’s pajamas?

The CPSC’s definition of children’s pajamas is quite broad and does not limit itself to products labeled as “pajamas.” It refers to any garment primarily intended for use during sleep or related activities (such as pre-sleep preparations, storytelling, and leisure activities at home), such as robes, pajamas, loungewear, long sleepwear, and so on.

Determining Factors:The CPSC considers the following factors when determining whether a garment qualifies as a children’s sleepwear:

The structure and style of the garment.

Whether it is suitable for sleep or sleep-related activities.

The way the product is being sold,promoted,and marketed.

Fabric characteristics(fiber composition,weight,print pattern,softness,etc.).

Instances where this fabric or similar fabrics have been used to make children's clothing in the past.Current market trends.

Labeling and record-keeping requirements:

Unit Identification:Each pajama must have a permanent label indicating its corresponding FPU or GPU number,which will aid in traceability during recalls.

Flame Retardant Care Label:The label must include cautionary instructions on how to wash the product to preserve its flame-retardant properties(e.g.,prohibiting the use of soap,as certain soaps can leave residues that affect the flame-retardant properties).

Tracking Label:As a child product,it must also comply with the tracking label requirements of the CPSIA(identity of the manufacturer/private labeler,production date and location,batch/run number,etc.).

Record Retention:Manufacturers and importers must retain all test records for a minimum of 7 years.

Common high-risk fibers:

The CPSC explicitly states that certain untreated natural fibers or regenerated fibers are typically unable to pass the tests outlined in Part 1616,including:

100%cotton

100%silk

100%rayon

100%modal

If it is intended to use these fabrics for producing children’s pajamas,the materials must be treated with a flame-retardant blend of fibers(such as modified acrylic)or undergo a durable flame-retardant finishing process,or consider meeting the exemptions for tight-fitting pajamas mentioned above.
