7.1.3 Propellant lots not meeting the required ballistics at the first proof or if the adjustment in muzzle velocity (mv) is more than 1% of V of A shall be subjected to reproof/repeat proof/special proof at the discretion of Quality Assurance Authority/Proof Officer. 7.1.4 The conduct reproof shall be the same as for normal proof either in full or in part at the discretion of Quality Assurance Authority/Proof Officer. Quality Assurance Authority also reserves the right to ask for special firings in the reproof of lot not catered for in the normal proof to the satisfaction of himself. Results of reproof/latest firing for acceptance shall be taken into consideration in awarding sentence, ignoring completely the results of previous proof.

7.1.5 Lots finally not meeting the ballistic requirements and having ACM more than the maximum loadable charge mass shall be rejected. 7.1.6 The check proof schedule in respect of Double Base Propellants is enclosed as under.

7.2 CHECK PROOF SCHEDULE 7.2.1 All bulk propellant lots/made up charges shall be dispatched to filing factories after receipt of serviceability/acceptance sentence after proof from AHSP/Proof Establishment. 7.2.2 The accepted bulk propellant lot(s) on receipt at filling factories shall be taken up for Ammunition filling as per charge mass (ACM) indicated/stipulated in the proof results and inspection note. In case of made up charges the same shall be taken up for filling directly.

7.2.3 The propellant l0t(s)/made up charges shall normally be filled in the ammunition as soon as it is received or at the earliest possible time.

7.2.4 However due to some exigencies, if there is long delay in filling any bulk propellant lot(s)/made up charges from the date of manufacture or date of last proof carried out then the said propellant lot/made up charge lot shall be check tested before filling.

--- --- 117

JSS 1376-12: 2003

7.2.5 A maximum period of Two Years from the date of last proof is permitted for filing the accepted bulk lot(s)/made up charge(s) lot(s). If above TWO YEARS periods are exceeded, the bulk pro-pellant lot(s)/made up charge. Lot(a) shall invariably be check tested before undertaking filling. Depending on the laboratory results of such check tests the propellant lot(s)/made up charge lot(s) shall be sentenced for either filling at original charge-mass or to submit the lot(s) for check proof, for adjustment of charge mass i.e. allotment of fresh charge mass if deemed necessary.

7.2.6 The representative samples from concerned bulk lot(s) (Not filled within the stipulated period as mentioned in Para 5) Shall be drawn by Resident Quality Assurance Establishment and forwarded to CQA (ME), Kirkee for carrying out following check test. The test results along with recommendation from CQA (ME) shall be forwarded to CQA (Ammunition), Kirkee.

7.3 IN CASE OF BULK LOOSE PROPELLANT

7.3.1.1 The propellant sample shall also be subjected to chemical stability tests to confirm the requirements w.r.t. chemical stability of the same.

7.3.1 The check proof shall be deemed necessary if the laboratory check test results on the propellant samples with respect to clause 6(i) & 6 (II) above exceeds the following limits when compared with original/last tested results.

(i) Moisture content/volatile matter content ± 0.1% (ii) Calorimetric Value ± 10 cal/g

7.3.2 In case of made up charges check weighing of 10 charges selected at random from; the lot shall be carried out. If no significant variation in charge mass is recorded from the ACM/ACW to which charges made, then check proof shall not be necessary and the charges can be filled in the ammunition at original ACM.

--- --- 118

JSS 1376-12: 2003

7.3.3 If there is significant variation, recorded during check weighment, the detailed results of check weighment shall be forwarded to CQA (ME) and CQA (Ammunition), Kirkee. Simultaneously representative samples from the charges shall be drawn by Resident Quality Assurance Establishment and forwarded to CQA (ME), Kirkee for determination of Moisture/Volatile matter content and calorimetric value as in Para 6(i) & 6(ii). CQA (ME), Kirkee shall forward the results to CQA (Ammunition) Kirkee with their recommendations. Check proof shall be considered necessary if the results of moisture/volatile matter content and calorimetric value exceeds the limit given in Para 7.

7.3.5 Final decision regarding check proof or otherwise shall be intimated to all concerned by CQA (Ammunition), Kirkee.

7.3.6 The check proof shall be carried out by proof establishment on receipt of proof samples duly sealed by the Resident Quality Assurance Establishment and as per guidelines issued by CQA (Ammunition) Kirkee. The detailed proof results with recommendation shall be submitted by the Proof Establishment to CQA (Ammunition), Kirkee for awarding final sentence.

7.3.4 In addition samples from both bulk propellant and made up charges shall also be tested for Heat test/Methyl Violet test for checking the stability of the propellant as a guidance for safety.
