Flammability Test — RTCA DO-160 Part 26 · Toy Testing

What Is Flammability?

This test is carried out to evaluate the ignition, burning rate and self-extinguishing behavior of equipment materials within the scope of Chapter 26 (“Fire, Flammability”) of the RTCA DO-160 “Environmental Conditions and Test Procedures for Airborne Equipment” standard. DO-160 is the exact same text as EUROCAE ED-14 and is recognized by ISO as ISO 7137.

Purpose of Flammability

The aim is to certify that aviation equipment meets the requirements regarding the evaluation of ignition, burning rate and self-extinguishing behavior of equipment materials in flight and ground conditions and to complete equipment qualification.

Which Products Is Flammability Applied To?

Avionics units and displays
In-flight electronic equipment
Communication and navigation devices
Cabin and cargo compartment equipment
Sensors and actuators

Sample Requirements for Flammability

Malzeme listesi belgelenmeli
Sample thickness should represent the most unfavorable use
Conditioning must be applied

Duration of Flammability

It is short per sample; one set is typically completed in one business day.

Flammability Procedure

1The method and flame duration are determined.
2The sample is placed in the holder.
3Flame defined time is applied.
4Burning time and length are measured.
5Flaming drop behavior is observed.

Flammability Acceptance Criteria

Acceptance criteria are maximum burning time, maximum burning length and flaming drop limits defined in the standard.

Evaluation of Results

Aviation flammability requirements for cabin interior materials also apply.

Accreditation

EUROLAB holds internationally recognised accreditation obtained from accreditation bodies party to the IAF and ILAC multilateral recognition arrangements, under ISO/IEC 17025 for laboratory testing, ISO/IEC 17020 for inspection and surveillance, and ISO/IEC 17021-1 and ISO/IEC 17065 for system and product certification. This chain ensures the reports and certificates issued are accepted worldwide.

Whether this test can be offered within accredited scope depends on your product and the standard applied; since accreditation is method-based, the scope is confirmed in writing at the quotation stage.

Oyuncak Testleri — What Does This Testing Field Cover?

The section below describes the field that the Flammability test belongs to; the conditions and acceptance criteria of this particular test are given in the sections above. The scope specific to your product is confirmed in writing at the quotation stage.

Toy testing shows that a product is safe in children's use. What sets this family apart is that risk is defined according to the USER: the same product may be hazardous for a child under 36 months and safe for an older child. Age marking is therefore not a marketing preference but a technical decision that determines which requirements apply, and it is justified in the technical file.

At the centre of the field is the risk of CHOKING. Children under 36 months put objects in their mouths; a part that detaches or is small to begin with can block the airway. Assessment with the small parts cylinder is the fundamental criterion for this group, and the tests examine whether the part detaches after use and misuse.

The logic of the tests is not that the toy must not break but that BREAKING must not produce a hazardous outcome. A child drops, pulls, bites and stands on a toy. Drop, tension, compression, torque, impact and tipping tests are therefore applied, and the resulting new state is then assessed: is the detached part a small part, did the broken surface leave a sharp edge, has the internal mechanism become accessible?

On the chemical axis, MIGRATION is what counts. What is measured in a toy is not how much of an element the material contains but how much of it dissolves and transfers under conditions simulating the mouth. Materials are divided into three categories (dry brittle powder, liquid or sticky, scrapable) and different limits apply to each; the amount of material a child could ingest varies by category.

Flammability is the third axis and is critical particularly for costumes, tents and plush toys: how quickly flame spreads across the surface is measured.

Electrical and battery-powered toys bring additional bodies of work: EN 62115 for electrical safety, the relevant battery standards and Battery Regulation obligations for the battery. For toys containing button cells, making the battery compartment impossible for a child to open has become a separate requirement — a swallowed button cell is a cause of serious injury.

Sound level is an item that is often overlooked. For toys used close to the ear (toy telephones, rattles, cap-firing toys) the sound pressure is limited; the risk of hearing damage is assessed.

Market regimes differ and do not substitute for one another: the Toy Safety Directive and CE marking in Europe, and in the United States the CPSIA with mandatory ASTM F963 and a third-party laboratory certificate (CPC). The United States also looks at total lead content while Europe looks at migration; the two approaches can produce different results.

Method groups in this field

Mechanical and physical
Small parts assessment, sharp edges and points, entrapment, cord and drawstring safety, dynamic strength, drop and tipping (EN 71-1).
Flammability
Rate of flame spread and ignition behaviour (EN 71-2); decisive for costumes and plush toys.
Element migration
Migration of specified elements in the three material categories (EN 71-3).
Organic chemicals
Phthalates, flame retardants, azo dyes, preservatives and fragrances (EN 71-9 and REACH restrictions).
Electrical toys
Electrical safety under EN 62115; heating, insulation, battery compartment and charging safety.
Sound and other
Sound pressure measurements; the requirements of EN 71-4 and EN 71-5 for chemistry sets and chemical toys.

Commonly confused in this field

Toy safety cannot be demonstrated with a single standard; the mechanical, flammability and chemical parts are assessed together.
Age marking determines which requirements apply; it must be justified in the technical file and not left to marketing preference.
An ASTM F963 report is not accepted in a CE file; the requirements and test arrangements of the two regimes differ.
Migration and total content are different things; the CPSIA looks at total lead while EN 71-3 looks at migration.
If the material category is chosen incorrectly the limit is applied incorrectly too; the category decision is made before sample preparation.
For toys containing button cells, battery compartment safety is a separate requirement; passing electrical safety is not sufficient.

Which decisions these results support

CE marking and the technical file
Determining age marking and warning texts
The CPC certificate and mandatory third-party testing for the US market
Supplier and lot-based acceptance control
Determining the scope of retesting after a design change

Frequently Asked Questions About Flammability

How is the equipment category determined?

The category is selected based on the equipment's mounting location on the aircraft (pressurized/non-pressurized, heated/unheated area) and aircraft type. Category selection directly determines the test conditions and is declared in the qualification form.

Is there any difference between DO-160 and ED-14?

No. RTCA DO-160 and EUROCAE ED-14 are exactly the same text; the two are considered equivalent.
