Type testing

Submission to the approval

§ 5 (1) has submission of ammunition to type test to be made using form of the fire Office ("submission sheet"). The form has to contain the following information:



1 (company) name and address of the sender;

2. date of filing;

3. name (company) of the manufacturer or the importer;

4. label the type of ammunition;

5. types of munitions are not contained in the ON rules specified in § 53 are the note, the submitted ammunition type is equivalent to what commercial description;

6. the estimated number of lots, which manufacture or import is intended;

7. the statement in which different types of execution (E.g. with different types of powder, bullet weights, percussion cap models, as use -, high - or fire ammunition) the submitted ammunition type in traffic to be brought;

8 where appropriate, the request of the importer, to grant the self-remedy of manufacturing control of this type of ammunition;

9. where appropriate, the request of the manufacturer or the importer, manufacturing control of this type of ammunition by the fire Office make to leave.

(2) an ammunition type for type test has deviations from the relevant for them, stated in article 53 ON rules, or it is included in any of this ON rule appropriate the form documents (descriptions, scale drawings, etc.), from which the deviations or the characteristics of the type of ammunition are clearly shown to connect. The type test is in this case on the basis of the complete information provided by the manufacturer carry out. In this case the permissible medium maximum gas pressure which must be no more than 4,400 bar, medium-sized gas pressure measured and everyone else by the manufacturer are in the decision (article 7 paragraph 2) to be made and to be checked in the framework of the audit of of types of information. This information is as to attract basis for the control of this caliber ammunition as long as, until that calibre was inducted into a technical standards work declared binding.

(3) is made when submitting an ammunition type for type testing, with the exception of shotgun ammunition, no information about the permissible medium maximum gas pressure, or has been determined the method of measurement by the provisions of the 3 main section of a different gas pressure after one, so the allowable is maximum gas pressure medium by multiplying the gas pressure measured in accordance with the provisions of the 3 main piece with the factor of 1.07 to set.


(4) when submitting an ammunition type to type test the self-remedy of manufacturing control of this type of ammunition by the importer not applied and will this also no request in accordance with paragraph 1 Z 9, a certificate of the manufacturer of this type of ammunition is the form to join, in which it confirmed that the production control of this ammunition type by him, by analogy with the provisions of the 4th section will be conducted. The importer has in this case for each of the Fabrikatinskontrolle carried out by the manufacturer on the basis of the test protocol created by the manufacturer imported Munitionslos evidence of to provide.

(5) when submitting an ammunition type to type test the self-remedy of manufacturing control of this ammunition type applied by the importer, so the permission to use the respective test equipment by the fire service is requested at the same time. A directory of existing test facilities, their exact description and corresponding, scale drawings are this request to connect.

(6) the ammunition for the type test is on the occasion of the submission in the number prescribed pursuant to § 6 and where for your transport bring to pass the fire Office provided Pack.

Sampling for type testing

§ 6 (1) has the sampling for the approval of a type of ammunition unless para 2 nothing else determines on a finished lot, whose quantity is at least 3000 pieces, to be carried out. Several lots of same ammunition type is to be used for the collection of samples that Los containing the ammunition with the highest maximum gas pressure specified by the manufacturer or importer.

(2) the type test is to make twice the number of the number resulting from the table of § 21 para 2 of ammunition. The approval for a type of ammunition, from within a calendar year, expected to be less than 3000 pieces are manufactured or imported, is to make each an in the same proportion to this number smaller quantities of ammunition.

Check of the components of the cartridges with lead-free grinding


Section 13 (1) cartridges with lead-free crushing in the sense of this regulation are cartridges, which homogeneous lead-free pellets with a hardness of 40 HV1 but 110 HV1 average (single value 125 HV1) (type B) or heterogeneous lead free pellets with a deformation contain 45% (type C). If lead-free pellets can be incorrectly classified as homogeneous or heterogeneous and not correctly associated with one of the above mentioned types on the basis of tests, the fire official from the submitter may require that tests the gun laying down the specifications of the cartridges (speed and pulse) are carried.

(2) heterogeneous lead free pellets with a deformation less than the of steel shot of the same diameter may be loaded not in cartridges.

(3) cartridges with lead-free crushing are in addition to check on their constituents. The control is considered to be passed, if any cartridge is designed, that avoids the friction of the Schrotes in the run and the shotgun in a sufficiently solid container (plastic, cardboard, or other material) is included. The tanks must withstand the shot at ambient temperatures in the range from-20 ° C to + 50 ° C.

Measurement of gas pressure

Types of gas pressure measurement

Section 25 (1) usually is the gas pressure by means of a pursuant to the provisions of the 4 main piece of calibrated mechanical electrical pressure transducer to measure. The gas pressure are represented in this case by the PT size designations or, if a Konformal pressure transducer is used by the dimension name PTc.

(2) the gas pressure, however, is with the help of upset cylinder method to determine if the gas pressure is specified in each case under consideration, stated in article 53 ON-rule was determined according to this method. The gas pressure are represented in this case by the PCr measurement labels or, if a Konformal pressure stamp used by the dimension marking PCrc.

(3) the gas pressure can be measured by way of derogation from the provisions of paragraphs 1 and 2, also after any other proceedings in the defined places, provided by comparative measurements, it has been demonstrated that the results obtained in this procedure correspond to those of the reference procedure. In this case, the necessary conversion is to perform.

Preparation and implementation of the gas pressure measurement

The pieces of ammunition to be tested are § 26 (1) the review of the medium-sized gas pressure for 24 hours at a temperature of 21 ° C to store 1 ° C and a relative air humidity of 60% ± 5%.
