Specitically, you ask whether chemical etching is an acceptable cylinder requalification The answer is yes. Requalification markings must conform to requirements in § 180.213, including minimal wall thickness and specifications for the marking size and location. Further, each cylinder must be plainly and permanently marked on the metal of the cylinder as permitted by the applicable specification. Provided all applicable conditions are met, the HMR permit the chemical etching of requalification markings on cylinders. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, stern ester -...... T.

Our agent in the US, a manager of Galiso called Adam on 28/July for us on this matter but he indicated us to submit a letter of interpretation to clarify the chemical-etching on the fire extinguishers. //Background// As for Ref /A/ Fire extinguisher, JAPCO used chemical-etching for the hydrostatic test marking (See Ref /D/ photo) before the vendor specified the marking method in Ref /B/ CMM. In Jan/2013 Ref /B/ CMM was revised to specify rubber stamp and ink as the marking method, then JAPCO has followed the method. Marking method JAPCO used in the past differed from the method specified Ref /B/ CMM. JAPCO would like DOT to accept fire extinguishers marked by chemical-etching in the past for continued use. //The reason for asking DOT// The vendor expressed no concern with using chemical-etching, but they recommended us to contact DOT and ensure that DOT accepts. When JAPCO contacted DOT, on 1st July Mr. Jordan suggested we should review your web site. We reviewed but found no information was posted to solve our issue. We asked Galiso to call DOT about this and Adam indicated on 28 July that we should submit a letter. Thus this is the letter. <<>> JAPAN AERO PRESSURE CO., LTD.

(4) Do the hydrostatic test as specified by 49 CFR 180.205. Use the Water Jacket Volumetric Expansion Method in CGA Pamphlet C-1. Do not do the hammer test. Test persons must know the contents of CGA Pamphlet C-1 to make a correct analysis of the results. WARNING: BE CAREFUL WHEN YOU DO THE HYDROSTATIC TEST. CALCULATE THE TOTAL, PERMANENT, AND PERCENT OF PERMANENT EXPANSION OF THE WELDMENT WITH PRECISION. DISCARD THE WELDMENT IF THE WALL DIMENSION IS LESS THAN SPECIFIED IN DESCRIPTION AND OPERATION, LEADING PARTICULARS. DO NOT DISCARD THE WELDMENT IF THE WALL THICKNESS IS CORRECT. (5) The test gives the total and permanent expansion of the weldment at a specified pressure. Total expansion minus the permanent expansion is the elastic expansion. Elastic expansion at a specified pressure is a definite measure of the average thickness of the weldment wall. (6) Divide the permanent expansion by the total expansion and multiply by 100 to calculate the percent of permanent expansion. If the total permanent volumetric expansion is more than 10 percent, discard the weldment. (7) Too much permanent expansion shows that the weldment wall is too thin or was in conditions that changed its dimensions. An increase in the elastic expansion shows a decrease in the average wall thickness. WARNING: INK IS CORROSIVE TO HUMAN TISSUE. DO NOT BREATHE VAPORS. USE IN WELL-VENTILATED AREA. PUT ON CHEMICAL-RESISTANT CLOTHING, GLOVES, SPLASH GOGGLES, AND FACE SHIELD. IN CASE OF EYE OR SKIN CONTACT, FLUSH WITH WATER FOR 15 MINUTES AND SEEK MEDICAL ATTENTION. (8) Use a rubber stamp and black ink to mark the date of the hydrostatic test on the weldment (90). Let the ink become dry. (9) Apply a thin layer of acrylic lacquer over the stamped data.
