What the testing involves

All the tests have been carried out by a UKAS accredited and independent testing house in accordance with the Coffin and Casket Testing Protocol developed between 2013-5.

The coffins have all been subjected to the following tests:

1. Strength Test

Using the largest product size available in the range, a strength test will be carried out by placing the product on a set of standard funeral trestles, the first being placed under the shoulder 300mm from the head end and the second 300mm from the foot end (as shown in Diagram 1).

The distance between the product and the floor will be measured at 3 points to the nearest millimetre (as shown in Diagram 1).

Diagram 1

The product's lid will be removed. The base of the product will then be loaded with weights up to its maximum stipulated load-bearing weight multiplied by 1.25.The weights will be distributed inside to represent the proportions of a body (head, torso & legs) across the base of the coffin. The lid will then be re-attached and fixed.

After 24 hours, further measurements from the same 3 points to the floor will be taken in mm.

Note: It is important that the largest sized product (as advertised as generally available) is tested. And if smaller sizes of the same model are made of thinner materials or use smaller amounts of screws, staples, dowels and/or glue at their joints, then a medium sized model must also be tested. All coffins and caskets whether alternative or traditional must be tested in the same way.

Determining Pass/Fail
If any of the 3 measurements between coffin base and floor have decreased by 28mm or more (i.e. if the base has sagged by 28mm or more) then this would be deemed a fail. A product which collapsed or otherwise failed catastrophically during the test would also be deemed a fail.
A fail will be photographed and a picture will be sent to the examinee company.

2 (a). Roller Bearing Bed Test

The product will be loaded to the same weight as in the Strength Test and its lid securely fitted in place. It will be placed on a standard crematorium roller bar bed (see Diagram 2) for 12 hours, after which it will be slid along the bed to simulate loading. This action will be repeated 12 times.

Diagram 2

Determining Pass/Fail
If the product becomes jammed or comes to a complete stop or fails to move in the direction in which it is pushed during the simulated loading this will be deemed a fail.
fail will be photographed and a picture will be sent to the examinee company.

2 (b). Ball Bearing Bed Test

The product will be loaded to the same weight as in the Strength Test and its lid securely fitted in place. It will be placed on a standard crematorium ball bearing bed for 12 hours, after which it will be moved across the bed to simulate loading. This action will be repeated 12 times.

Determining Pass/Fail
If the product is heavily dented or punctured by the bearings and/or becomes stuck, or fails to move in the direction in which it is pushed during the simulated loading this will be deemed a fail.
fail will be photographed and a picture will be sent to the examinee company.

3. Auto Charger Test

The product will be loaded to the same weight as in the Strength Test and its lid securely fitted in place. Charging will be simulated using a charging arm and plate measuring 300mm x 300mm. The plate is placed at the end of the coffin at a point in the centre of the end face and a force applied similar to that used in a crematoria (see Diagram 3).

Diagram 3

The force specified as being typical of a crematoria charging is 3KN. To ensure that a force of at least 3KN is applied, the start point will be marked and recorded at the front of the coffin and the horizontal distance travelled during simulated charging will be noted. The weight of coffin plus load is also determined and recorded and the applied force calculated.

The test is conducted moving the coffin in a horizontal traverse across both a standard crematorium roller bed and also a horizontal concrete surface in order to simulate the cremator hearth. At the end of the test the coffin will be inspected and any damage/deformity to the framework will be noted.

Determining Pass/Fail
A product will fail if it deforms noticeably and/or it breaks open.
A fail will be photographed and a picture will be sent to the examinee company.

4. Mechanical Insertion Machine Test (optional)

The product will be loaded to the same weight as in the Strength Test and its lid securely fitted in place.

The product will then be placed on a rig built to mimic the TABO machine presently in service at some crematoria for a period of 10 minutes.

Determining Pass/Fail
If the product distorts around the supporting fingers so that it cannot be released or if the product collapses this will be deemed a fail.
A fail will be photographed and a picture will be sent to the examinee company.

Note: This test is optional as there are currently only 10 TABO machines in operation.


5. Ignition/Radiant Heat Test

A 150mm square (minimum) sample of the product will provided. This sample will be clamped vertically at a distance of 300mm from the heat source to simulate a coffin approaching the cremator during charging. The heat source utilised will be a laboratory scale furnace where the heat source cross-sectional area is 20-30% larger than the cross-sectional area of the sample material. The exposure cycle will start at 400C and the heat source temperature will be increased at a rate of 100C every 10 seconds, achieving a final temperature of 700C. The heating process will be viewed continuously during the test and any smouldering or combustion noted.

Determining Pass/Fail
If the material ignites below a temperature of 580C this will be deemed a fail.
A fail will be photographed and a picture will be sent to the examinee company.

6. Ash test

A representative sample of the product weighing 1kg (minimum) will be placed on a heat resistant ceramic surface and exposed to cremator conditions of 800C until fully combusted. When cool, the ash will be pushed through a mesh sieve (150 microns approx) to replicate the cremulation process. The weight of the ash material will be recorded and expressed as a volumetric percentage for the largest product and including an estimate for the deceased. Using this data the complete ash volume will then be calculated in litres.

Determining Pass/Fail
Ash volume calculated to be in excess of 6 litres would be deemed a fail.


7. Ash Residue Test

The ceramic surface used in the Ash Test will be inspected for sticky or solid residue. Any residue will be photographed and bagged and returned to the manufacturer .The sample must not leave residue that has a detrimental effect to the hearth surface or to the quality of ashes returned.

Determining Pass/Fail
If residue was evident as above this would be deemed a fail.
A fail will be photographed and a picture will be sent to the examinee company.

8. Handle Test (optional)

The product will be loaded to the same weight as in the Strength Test and its lid securely fitted in place. The product will then be suspended from all of its handles by means of webbing straps and left for 12 hours.

Determining Pass/Fail
A fail would be if any handle became detached from the product or a handle failed.
A fail will be photographed and a picture will be sent to the examinee company.

Note: This test is optional as many types and styles of handle are added for decoration purposes or to guide the coffin only; and not for load bearing purposes.


9. Lining Test (optional)

A sample of the product's lining measuring minimum 200mm x 200mm will be suspended from its four corners so that its middle point is at least 10mm lower than the edges. Water mixed with 10% formaldehyde solution will be poured into the depression to achieve a depth of 10mm. This will be left to stand for 5 hours. Any leakage or adverse reaction will be recorded.

Determining Pass/Fail
Any leakage of the liquid through the liner will be deemed a fail.
A fail will be photographed and a picture will be sent to the examinee company.

Note: This test is optional as not all products are supplied with leakproof liners.
