TMT Basic Policies Extract

The following was extracted from the 1997 TMT Policies Introduction and gives the reader the basic guidelines regarding TMT Policy, submission and testing.

1-1.0 The Tripoli Motor Testing and Listing Committee (TMT) is a service division of the Tripoli Rocketry Association, Inc. Its main purpose is to test commercially manufactured rocket motors and to certify them as declared by the manufacturer, suitable and approved for use by certified members of this organization.

1-7.0 The TMT Committee shall be the authority to declare a party as a legal commercial manufacturer after said party provides the proper required information and proof.

2-2.1 Applicants must fill out and submit the completed application to the TMT Committee with at least three of the following:

2-2.2 In addition to the above the applicant must obtain and submit an "EX" number assigned for a particular propellant formulation by the U.S. Department of Transportation/ Research and Special Programs Administration (US DOT/RSPA). This agency issues this number on a recommendation by the Bureau of Explosives (BOE), Canada Center for Mineral and Energy Technology/Canadian Explosives Research Laboratory (CANMET/CERL), or any other agency approved by the competent authority of the United States. The recommendation for classification is given when the applicant provides propellant and other required information for testing. The applicant must also provide TMT with a copy of a BATF Low Explosive Manufacturer's license prior to acceptance of motors for testing. This requirement is by Tripoli Board motion and vote on 23 January 1994.

2-3.0 The applicant must also sign an agreement to make good any and all damages caused by the failure or operation of any and all motors submitted by them for testing. This agreement will be a legal and binding document and must be sworn before a Notary Public before any motors will be accepted for testing.

2-4.0 Motors will be accepted for testing only when submitted by their specific manufacturer. Individuals, distributors, agents or other interested parties not directly involved in the specific operation of the motor manufacturing company shall not be permitted to submit, or be a part of the motor certification process.

3-1.0 High power rocket motors are to be packaged, labeled and shipped in accordance with Title 49, Code of Federal Regulations.

4-2.1 For new certification of high power rocket motors the following number of motor types will be required for Tripoli certification:

Disposable Motors
H through L class motors - three (3) of each

Reloadable Motors
H through L class motors - three (3) of each

4-2.2 For re-certification of high power rocket motors the following number of motor types will be required for Tripoli certification:

Disposable Motors
H through L class motors - two (2) of each

Reloadable Motors
H through L class motors - two (2) of each

4-3.1 For new certification of advanced high power rocket motors the following number of motor types will be required for Tripoli certification:

Disposable Motors
M through O class motors - two (2) of each delay time

Reloadable Motors
M through O class motors - two (2) of each delay time

4-3.2 For re-certification of advanced high power rocket motors the following number of motor types will be required for Tripoli certification:

Disposable Motors
M through O class motors - one (1) of each delay time

Reloadable Motors
M through O class motors - one (1) of each delay time

5-1.0 All motors submitted for Tripoli testing must be engineered and constructed in such a way that in the event of a motor failure dis-assembled pieces, parts and fragments will not fail in other than the longitudinal axis of the motor, nor will fragments project further than:

5-2.0 All motors submitted for Tripoli testing must include the manufacturer's:

5-3.0 If the manufacturer does not provide the above information, or if the information provided is not correct, TMT will not be responsible for the loss of data and another motor will be required of the manufacturer to complete the testing of that motor type.

5-4.0 Reloadable motors shall include three (3) motor casings and hardware sets for each diameter of motors submitted for testing. These casings will stay in TMT possession after testing unless specifically requested to be returned by the manufacturer and return shipping fees are paid by the manufacturer.

5-5.0 All motors submitted shall have date of manufacture, or equivalent code, on the casing or the reload package.

5-7.0 All motors shall be so designed, engineered and constructed that the over temperature of the casing shall not exceed 200°C at any time during or after the test. (Small isolated spots may exceed this slightly if the rest of the case is substantially below 200°C.)

5-8.0 Delays will be so designed so any discrepancy will not exceed 20% of the stated time on the case or reload package, not to exceed three (3) seconds.

6-4.0 Motors will be declared as failed if any of the following occur:

9-5.0 Once approval expires, the motor is no longer legal for use at Tripoli sanctioned launches. Re-submittal and retesting are necessary for the motor to continue to remain on the "Approved" list.

13-1.0 If a motor fails catastrophically and damages and/or destroys the test stand, or any components thereof, the manufacturer of the failed motor shall be billed for any and all repairs or replacement of involved equipment.

13-2.0 If damages are not paid in full within 30 days of the incident no further motors will be accepted or tested by TMT until such time that payment is made in full.

13-3.0 If damages are not paid in full within 60 days of the incident certification for that manufacturer shall be removed and their motors will not be approved for use by Tripoli members.

14-1.0 The Tripoli Motor Testing Committee reserves the right to refuse the testing of any motor(s) submitted based on the Chief of Testing's opinion that said motor(s) are physically unsuitable, (i.e., bad epoxy, case damage/flawed, propellant voids, poor engineering), and would be of potential danger to the crew and/or test stand.
