Overview
ASTM F1967-19: Standard Consumer Safety Specification for Infant Bath Seats was developed by ASTM International to promote the safe design, testing, and labeling of infant bath seats. This standard aims to reduce the risk of drowning, injury, and product failures associated with these products, including those commonly referred to as bath rings. The specification details clear performance, labeling, and instruction requirements to ensure caregivers are fully aware of safety concerns and use limitations. Note that traditional infant bathtubs are not within the scope-only seats intended to support infants while being bathed are covered.
Key Topics
ASTM F1967-19 covers several critical areas essential for manufacturers and regulators aiming to produce, import, or market compliant infant bath seats:
- Performance Requirements: The standard mandates rigorous evaluation of stability, resistance to collapse, and prevention of hazardous points or edges to minimize injury risks.
- Test Methods: Clear protocols, including load testing, suction cup effectiveness, and component durability, ensure products meet safety benchmarks.
- Labeling Requirements: Comprehensive labeling ensures that critical warnings (such as drowning risks and age limitations) are very visible, permanent, and meet legibility standards aligned with ANSI Z535.4.
- Installation Components: All vital installation elements-such as clamps, arms, and suction cups-must be permanently attached before shipment to prevent accidental detachment.
- Small Parts and Paint: Adherence to federal regulations concerning small parts (to prevent choking hazards) and lead content in paints is required.
- Instructional Literature: Manufacturers must provide clear instructions for safe assembly and use, as well as maintenance and warnings.
- Consumer Product Safety: The specification is in alignment with relevant US federal regulations, including the Consumer Product Safety Improvement Act.
Applications
ASTM F1967-19 applies to:
- Manufacturers: Those who design, fabricate, and distribute infant bath seats must utilize this standard to guide product development and ensure regulatory compliance.
- Importers and Retailers: Compliance with ASTM F1967-19 is essential for supply chain partners to confirm products meet North American safety expectations and avoid recalls or import refusals.
- Product Safety Assessors: Regulations and in-house quality assurance teams use these criteria to benchmark safety before products reach consumers.
- Consumer Education: Through standardized labeling and warnings, caregivers are better informed about safe usage - crucial in preventing accidents stemming from misuse or lack of supervision.
- Testing Laboratories: The specified test methods provide detailed, repeatable instructions for product safety testing, including static load, stability, and the effectiveness of suction-cup attachments.
Adoption or referencing of ASTM F1967-19 can be required for legal compliance in many jurisdictions or as part of private-label certification programs emphasizing child product safety.

Standard Consumer Safety Specification for
Infant Bath Seats
This standard is issued under the fixed designation F1967; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This consumer safety specification is intended to address certain incidents associated with the use
of bath seats, bath rings, and other similar devices.
The U.S. Consumer Product Safety Commission (CPSC) identified drowning incidents which
generally involved infants either tipping over, climbing out of, or sliding through the product after
being left unattended by their caregiver.
This specification does not address incidents in which bath seats are unreasonably misused, are used
in a careless manner that disregards the warnings and instructions that are provided with each product,
or those instances where the caregiver leaves the infant unattended in the product.
This consumer safety specification is written within the current state-of-the-art product technology.
It is intended that this specification will be updated whenever substantive information becomes
available and known to ASTM which necessitates additional requirements or justifies the revision of
existing requirements.
1. Scope
1.1 This consumer safety specification establishes performance requirements, test methods, and labeling requirements to
promote the safe use of infant bath seats. Products commonly referred to as bath rings also are included in the scope of this
specification. Traditional infant bath tubs that are used to bathe an infant are not within the scope of this standard.
1.2 This consumer safety specification is intended to reduce the risk of death and minimize injury to infants resulting from use
and reasonably foreseeable abuse of infant bath seats.
1.3 No infant bath seat produced after the approval date of this consumer safety specification shall, either by label or other
means, indicate compliance with this specification unless it conforms to all requirements contained herein.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.5 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard
does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this
standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory
limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

(a) Solution comprised of ingredients as shown in Table 1, or
(b) Johnson’s baby head-to-toe baby wash, or
(c) Aveeno baby wash and shampoo.
7.4.1.6 Inclinometer with a measurement tolerance of less than or equal to 0.5°. The maximum weight of the inclinometer and
the fastening method shall be ≤2.2 lb (1 kg).
7.4.1.7 Test Bar—A 1 in. by ⁄4 in. (25 mm by 6 mm) rigid aluminum flat bar. The length of the test bar shall be such that it
extends beyond the uppermost edge or surface of the product at least as far as the maximum distance D as calculated below plus
enough additional length to accommodate the attachment of the inclinometer as described below.
7.4.2 Test Surface #1 Preparation:
7.4.2.1 Determine the coverage area for a product that contacts or attaches to the bottom surface of an adult bath tub for its
support and stability. Clean the coverage area with any commercial cleaner intended for bath tubs, following the cleaner’s
instructions. Then wipe the coverage area with alcohol and allow to dry.
7.4.2.2 Apply the safety tread strips evenly onto the coverage area at a distance of 0.375 6 0.125 in. (9.5 6 3 mm) apart from
edge to edge.
7.4.2.3 Safety tread strips shall be replaced if they become damaged or dislodged from their specified position(s).
NOTE 3—The installation of the safety tread strips for Test Surface #1 will most likely need to be done only during the initial setup of this test surface,
except for replacements that may be necessary from time to time.
7.4.3 Test Protocol for Test Surface #1:
7.4.3.1 Clean the coverage area with any commercial cleaner intended for adult bath tubs following the cleaner’s instructions.
Then wipe the coverage area with alcohol and allow to dry.
7.4.3.2 Use the spray bottle with the baby wash solution to thoroughly saturate the coverage area that is above the water level
specified in 7.4.3.3.

FIG. 4 Test Platform A-A Sectional View
7.4.3.3 Fill the test platform with clear water that is at an initial temperature of 100 to 105°F (37.8 to 40.6°C) to a depth of 2
in. (51 mm) above the estimated highest point of the occupant seating surface when the product is installed.
7.4.3.4 Install the product according to the manufacturer’s instructions onto the test surface. If the product has more than one
manufacturer’s recommended use position, select one position for the initial test.
NOTE 4—If necessary, adjust the water level to the 2-in. (51-mm) requirement by either adding or removing water from the test platform.
7.4.3.5 Securely attach the test bar to the inside edge of the occupant seating space in a vertical orientation at the position that
is most likely to cause the bath seat to tip over, with the widest surface of the test bar facing outward from the product.
7.4.3.6 Calculate the distance D for a force to be applied to the test bar using the following formula:
D 5 ~20.4 in. 2 H!/2 @~518 mm 2 H!/2# (1)
where:
H = the height of the uppermost edge or surface above the lowest point of the occupant seating surface.
7.4.3.7 Securely install the inclinometer to the test bar above the location where the force in 7.4.3.6 is to be applied. Measure
and record the pre-test angle of the test bar.
7.4.3.8 Apply a 17.0 lbf (76.5 N) force to the test bar at distance D above the height H. Apply the force perpendicular to the
test bar and outward from the center of the product over a period of 5 s (see Fig. 6). Maintain this force for an additional 10 s.
If the product begins to release from the test surface, continue to maintain this force perpendicular to the test bar until the product
either tips over or the 10 s time limit is attain
