STANDARD PRACTICAL INSTRUCTION FOR PHOTOGRAPHIC PROCESSING TEST TITLE　 PHOTOGRAPHIC PROCESSING TEST APPROVED BY DATE SPI　No. CHECKED BY DATE REVISED FROM PREPARED BY DATE APPLIED ON USER PAGE 2. SCOPE This standard provides the operation procedure for the photographic processing test of working solution and replenisher of photographic developing solutions. APPARATUS, PHOTOGRAPHIC MATERIALS AND REAGENTS 3-1. Apparatus Water bath Processing tanks (500 – 1000ml stainless steel or glass tank) Processing reels and holders for 135mm film (Plastic or stainless steel material) Thermometer (Range:0 – 50’C, Accuracy: +/- 0.1’C) Timer for dark room operation Densitometer (useful for both of transmission and reflection density measurement. (Example: X-lite densitometer) Dark room Freezer for stock of exposed photographic materials (-18 ‘C) 3-2. Photographic materials ad reagents Exposed photographic materials Konica color negative film CNK-4 control strips (ISO 200) These control strips are supplied from Konica and a Konica dealer. Konica color paper QA - A7C strips These exposed strips are supplied from Konica Technical Division. Standard solutions and Starter solution for each developer. Raw materials for mixing standard solutions. Recording form. 4. PREPARATION OF DEVELOPER SOLUTIONS 4-1. Preparation of sample developer solution for test. Mix the specified weight of each part of replenisher in water to make 500 – 1000ml of replenisher and verify that pH and specific gravity are within limits. Mix the said replenisher, starter and water to make 500 – 1000ml of developer solution and verify that pH and specific gravity are within limits. Mixing formula is showed in the standard production procedure for each product. 4-2. Preparation of standard developer solution. Mix the specified weight of each raw materials of replenisher in water to make 100 – 500ml of standard part for replenisher and verify that pH and spe
