Product Designation

The product designation is OOT-APRV-067 Power Charge Family, Types A and B (D/N: OOT-APRV-067, Rev

B).

These articles are manufactured by Owen Oil Tools at the address listed above.

This is a(n) not a new explosive report. Analysis for this report was conducted on 5/22/2019.

Product Description

The OOT-APRV-067 Power Charge Family consists of power charges used in setting tools in the oil industry.

This family has been previously tested and approved (reference EX2017122035) at its maximum loading.

Owen Oil Tools is altering the distribution of the ignition and base propellants; defining the original parts

as "Type A" and adding a new set of parts to the family defined as "Type B". Type B will have the same

NEW as Type A, the same maximum length and diameter, and will not include any additional chemical

formulations. A comparison between the energetics and their distributions in the A and B variants is

shown in Table 1.

Table 1. Comparison of OOT-APRV-067 Types A and B

Type A (EX2017122035) Type B (Subject of this report)

Base Propellant 5280-g, max 5265-g, max

Igniter Pellet 10-g, max 5-g. max

Starter Mix - 25-g, max

Total NEW 5290-g, max 5290-g, max

The starter mix is being added to increase the reliability of ignition of the power charge in service. The

starter mix is a blend of the base propellant with a maximum of 5-g of powdered black powder or BKNO3.

All of these energetics were approved in the previous family, and the igniter mix (BKNO3 or black powder)

is still limited to 10-g within the article, the only change is the distribution of the igniter composition within

the article, as seen in Figure 1.

Packaging Examined

Inner Trays, fiberboard containing one (1) article.

Intermediate None.

Outer UN 4G fiberboard box containing two (2) inner packages.

The outer package tested had dimensions of 32 in x 12 in x 7 in.

Justification for not a new explosive recommendation

The OOT-APRV-067 Power Charge Family has been previously tested (reference ETC Report 2017182,

attached) and approved (reference EX2017122035, attached) based on testing conducted by the author.

Owen Oil Tools is proposing a change where the igniter composition is split from its maximum 10-g pellet

(currently approved) to a 5-g pellet and blending 5-g of the composition with up to 20-g of base propellant,

shown in Figure 2 as the “starter mix”. The change proposed by Owen Oil Tools does not alter the

energetic formulations, the energetic mass, the relative proportion of the base and igniter compositions,

the size of the article, or the function of the article. In the previously approved Family the base propellant

and igniter composition are in intimate contact, the igniter pellet is pressed into the base propellant

during processing and allowed to cure in the base propellant.

This change will not affect the results of the tests conducted, detailed below.



Figure 2. Comparison of OOT-APRV-067 Types A (top) and B (bottom) showing the starter mix

UN 4(a): Thermal Stability Test – There is no change to the energetic compositions within the article, the

relative amounts of the compositions or the materials with which the energetics are in contact. As tested

the igniter composition and base composition were in intimate contact, in the Type B iteration of the

article, this contact is maintained. OOT-APRV-067 Power Charge Type B would give a negative result in

the UN 4(a) Thermal stability test.

UN 4(b)(ii): 12-m Drop Test – There is no change to the energetic compositions within the article, the




the UN 4(b)(ii) 12-m drop test.

UN 6(a): Single Package Test – There is no change to the energetic compositions within the article, the




the UN 6(a) Single package test. Owen Oil Tools performed internal testing, confirming that the Type B

variant gives a negative result in the single package test (reference OOT Lab Report PRJ-1102-LTR-24). The

author of this report was not present to witness the internal Owen Oil Tools testing.

UN 6(c): External Fire Test – There is no change to the energetic compositions within the article, the



article, this contact is maintained. Owen Oil Tools performed internal testing, confirming that the Type B

variant gives results consistent with Division 1.4 in the external fire test (reference OOT Lab Report PRJ-

1102-LTR-24). The author of this report was not present to witness the internal Owen Oil Tools testing.



Conclusion

There is no change to the energetic compositions, energetic loadings, size or packaging of the OOT-APRV-

067 Power Charge Family. The change proposed merely alters the distribution of one of the compositions

within the article. This will not alter the hazard of these articles when offered for transportation. This

does not constitute the creation of a new explosive. This conclusion IS packaging dependent. The

maximum allowable NEW per package should be limited to 10.58kg and the use of metallic packagings

should not be allowed without testing due to potential confinement issues

Recommendation

Add Type B to the OOT-APRV-067 Power Charge Family, Types A and B (D/N: OOT-APRV-067, Rev B) to

the existing approval EX2017122035, retaining the current classification of:

Cartridges, power device; UN0276; 1.4C

Testing Conducted and Results

UN Test 4(a): Thermal stability test for unpackaged articles and packaged articles - This test was

conducted in accordance with the UN Recommendations on the Transport of Dangerous Goods –

Manual of Tests and Criteria, 6th Revised Edition. The result of this test was negative. There was

no explosion or ignition of the tested articles, no temperature rise exceeding 3°C, no damage to

the outer casing or dangerous exudation.

UN Test 4(b)(ii): Twelve metre drop test - This test was conducted in accordance with the UN

Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria, 6th

Revised Edition. The result of this test was negative. There was no explosion or ignition of the

tested articles in any of the three drops.

UN Test 6(a): Single Package Test - This test was conducted in accordance with the UN

Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria, 6th

Revised Edition. The result of this test was negative. There was propagation between the donor

charge and the acceptor, with an average burn time of approximately 17 minutes; there was no

damage to the witness plate beneath the package and no disruption of the confining material in

any of the trials conducted.

The OOT-APRV-067 Power Charge Family is intended to function by deflagration, and designed to

ignite in a heavily confined metal tool. The articles were not provided with their own means of

ignition, as they and the igniters ship separately. The typical means of ignition, an oil field igniter,

was not available for testing, therefore it was replaced with an electric match and 10g of black

powder. This was successful in igniting the BKNO3 ignition pellet, but due to a lack of

confinement, was insufficient to ignite the main charge. To ensure ignition of the article a section

of road flare was used to provide a more sustained pyrotechnic ignition source. This is in

accordance with paragraph 16.4.1.3.3(a) of the UN Manual of Tests and Criteria, which states “the

article’s own means of initiation or ignition is replaced by another form of stimulus having the

required effect.” The section of road flare achieved the required effect (by igniting the main

charge) without influencing the results of the UN 6(a) single package test.

UN 6(c): External fire test – This test was conducted in accordance with the UN Recommendations

on the Transport of Dangerous Goods – Manual of Tests and Criteria, 6th Revised Edition. Four

outer packages were tested in the external fire test, representing a total volume of slightly more

than 0.15 m3. The articles initiated approximately 2 min. 30 sec. after the start of the fire, and

burned with a thick smoke until 8 min. 30 sec. The flame from the articles was difficult to

distinguish from the flames of the external fire test. The test resulted in no mass explosion, no

damage to the witness panels and no fiery projections. After testing, the articles were found to

have been burned away with some ash left on the table. There were no projections which would

fall above the 8 J curve in Figure 16.6.1.1 in the UN Recommendations on the Transport of

Dangerous Goods – Manual of Tests and Criteria, 6th Revised Edition. The articles burned for

approximately 6 minutes. This 360 second burn time can be interpreted in two ways:



1. The substance burned as a single 42.32kg mass burning over the course of 360 seconds. Using

these data and a conservative energy of 12,500 J/g, the heat flux at 5 meters is calculated as

1.54 kW/m2, which is on the 1.4S side of the 1.4/1.4S cutoff of 2.25 kW/m2 and minimum

burning time of 248 seconds.

2. The substance burned in eight discreet events, each 5.29kg mass burning for 45 seconds.

Using these data and the same conservative energy of 12,500 J/g, the heat flux at 15 meters

is calculated as 0.17 kW/m2, which is on the 1.4 side of the 1.3/1.4 cutoff of 0.56 kW/m2 and

minimum burning time of 13.1 seconds.

The actual burn time and heat flux values for this substance is somewhere in between the

extremes represented above. This substance behaves in a manner consistent with Hazard

Classification or Division 1.4 in both cases.

Conclusion

The OOT-APRV-067 Power Charge Family has been tested in accordance with 49 CFR §173.56 and has met

the requirements set forth for UN0276 Cartridges, power device, Hazard Classification or Division 1.4C.

This conclusion IS packaging dependent. The maximum allowable NEW per package should be limited to

10.58kg and the use of metallic packagings should not be allowed without testing due to potential

confinement issues.
