Annex II
Technical conditions for testing weapons in their verification
Verification of new weapons and domestic production
I. Inspection of the weapon before trial shooting
Each weapon is subjected to a pre-test shooting inspection
(a) a general inspection at which arms, rust or insufficiently polished on the outside and arms with damaged arms, are rejected. Weapons having:
- manufacturing defects in the drill and chamber,
- not sufficiently polished, mainly including the chamber of charge, which does not allow effective control,
- cracks or porous or incomplete and sealed areas on the barrel and at the end,
- an insufficiently dimensioned conclusion,
- bent barrel,
- a defective function to prevent safe execution of the test shooting;
(b) checking the dimensions of the drill and the chamber of charge with limit calibers, in which they are rejected principally, the dimensions of which are not in conformity with international or domestic regulations or with factory data engraved on the weapon;
(c) checking the thickness of the wall of the main, in which they are rejected mainly with locally or generally weakened walls (which do not have the minimum wall thickness prescribed by the State), as well as insufficiently connected main bundles. The eccentric bore is considered as a weakening of the wall barrel. Shotgun main is checked by tapping the copper gavel of 50 g mass and a thickness meter in the transverse cone and before inclusion. If deemed necessary by the State Service, the wall thickness of the main other weapons shall be checked accordingly;
(d) control of the closing will by means of pedestal meters for weapons with tilting heads and locking calibers for other weapons. Weapons whose joint between the barrel and the end is 0,1 mm or greater in the case of weapons with tilting heads or whose clearance is greater than 0,15 mm for other weapons shall be rejected. Weapons whose barrel is wobbling are also rejected;
(e) control of the percussion and triggering devices in which the weapons, the firearm of which exceeds too much, is too short, has great will or is too sharp. Weapons whose trigger resistance is too low or does not correspond to the prescribed values shall also be rejected, weapons which are liable to self-start, the cocks of which are not adequately held in the grips or the fuse (s) of which are not functioning properly.
II. Test shooting
(1) After the pre-test shooting inspection, the weapons shall be subjected to a test shooting which shall be carried out on weapons of complete external and internal dimensions, either in a still white or already black state; in any case before the first shooting test. The State Service shall determine whether to verify the weapon in white or black.
(2) The test charges shall comply with their technical specifications and shall be used at a temperature of + 15 ° C to + 25 ° C when the mean value of their pressures from the series of measurements meets the prescribed values.
(3) The pressure of the test charges shall be measured with a copper pressure gauge cylinder diameter of 3 mm and a height of 4,9 mm in the pressure gauge core at a temperature of + 20 ° C with a tolerance of ± 2 ° C, and shall be subtracted from the statically obtained tensile table. The pressure of the test charges for expansion devices may be measured, if necessary, in such a way as to be the most reliable or reliable for the instrument.
(4) Pressure measures must mainly comply with international regulations and recommendations.
(5) The different types of weapons and their separate parts shall be subject to fire by test rounds as follows:
(a) Smooth-bore weapons intended for shotgun hub and main-shotgun semi-finished products (which means a white barrel with definite internal and external dimensions, excluding hooks and hooks) shall be tested with two shots of test rounds on the barrel which give prescribed pressures (or pressures higher) at the prescribed places and then at least one shot of the consumable hub to verify the function of the repetitive or automatic weapon.
Pressurised pressures in kp / cm2 (in bars) and prescribed places are:
| Ráže | Délka nábojové komory | |
|---|---|---|
| menší než 76 mm | ||
| 1. tlakoměr | 2. tlakoměr | |
| 16 a větší | 920 (900) | 510 (500) |
| 20 a menší | 1020 (1000) | 510 (500) |
| Ráže | Délka nábojové komory | |
| 76 mm a delší | ||
| 1. tlakoměr | 2. tlakoměr | |
| 16 a větší | 1020 (1000) | 510 (500) |
| 20 a menší | 1120 (1110) | 510 (500) |
Note:
1. pressure gauge means a measuring point 17 mm from the bottom of the end bed;
2. by pressure gauge instead of 162 mm from this bottom.
(b) Slotted-bore weapons intended for spherical rounds shall be tested with two rounds of test rounds per chamber, and then with at least one shot of the cartridge per chamber for verification of the function of the repetitive or automatic weapon. The test charges apply a pressure of at least 30 per cent higher than the mean of the pressure determined by firing a sufficient group of strongest consumables.
(c) The weapons intended for the Flobert cartridges shall be tested with two rounds of the cartridge for the cartridge chamber. The ball test shells are filled with dust throughout the shell volume and have the heaviest consumer missile; Shock test shells have an increased load of buckshot.
(d) Expansion apparatus shall be tested in the same way as the arms ad (b), except that the function of each apparatus shall be verified by at least one charge shot.
(e) Ballistics shall be tested as an appropriate type of weapon; taking into account that weapon verification test cartridges may be used as consumables in ballistic weapons.
(f) The exchange of barrel shall be tested by means of its own conclusion in a manner consistent with the type of weapon concerned.
(g) separately supplied mainly and conclusions shall be tested as an appropriate type of weapon. The conclusions applicable to the main different calibre shall be tested as a shotgun, if at least one shotgun barrel, as well as a ball gun, if at least one ball barrel is attached to it. If the end is intended for several different shotgun or ball calibrations, the most strenuous test charges shall be tested. The stress criterion is the force at the end.
h) Gas weapons, which are close to the hazards of firearms in their concept, are tested with a pressure 30% higher than the maximum operating pressure.
(6) The tests shall be carried out by means of lafets which protect the operator safely and in which the weapons are fastened to the extent possible in accordance with the conditions of their use. The test fire shall be carried out on multi-barrel weapons gradually, i.e. barrel by barrel.
(7) If, during the test shooting, the pressure of the test charge is reduced by leakage of gases, the charge shall be replaced. If the replacement charge fails, the test room may replace it several times as necessary.
III. Inspection after test shooting
Weapons shall be refused during the post-test shooting inspection:
(a) which could not be charged and detonated;
(b) which cannot be removed by means of an extraction device;
(c) of which principally have any length of deformation or cracks;
(d) which have failed to connect the main platforms and hooks;
(e) which have increased the clearance clearance above the leave limit;
(f) in which the conclusion or any other device of the weapon has been breached;
(g) where the casings show a defect in the processing of the chamber of charge or in the blow of the firearm (smashing of the match, weak firing of the firearm or incorrect position of the ignition socket).
Verification of weapons from import
Weapons imported from abroad whose certification marks are not recognised in the Czechoslovak Socialist Republic shall be verified according to the section: And this annex, with the exception that in the case of weapons with tilting heads:
(a) measures the length of the principal to an accuracy of 1 mm;
(b) measure the diameter of the barrel of the shotgun to the nearest 0,1 mm;
(c) weighing mainly without the foreskin to an accuracy of 1 g;
(d) the Brinell test shall determine the strength of the material and determine from this test whether the thickness of the wall is mainly satisfactory.
New arms verification
The new verification of weapons (Section 3 (4) of the Decree) is carried out in the same way as the verification of weapons from imports (Section B of this Annex).
However, the State Service may tolerate:
(a) minor damage to the stock;
(b) weak corrosion inside and outside the weapon;
(c) a small transfer of the dimensions of the wells and the chamber;
(d) a gap between the main face and the head of the end for weapons with tilting heads of 0,1 mm or more (but not exceeding 0,2 mm),
(e) slight deformation in the upper third of the shotgun barrel (at mouth),
(f) minor percussion of the main.
Verification of gas weapons from domestic production
Domestic gas weapons subject to the verification obligation (Section 3 (2) of the Decree) shall be verified by the examination centre to satisfy itself:
(a) for each piece of gas weapon, as well as the accuracy of its essential function;
(b) for 3% of the quantities of gas weapons submitted, that the parameters of these randomly selected pieces and the approved sample are identical.
