(b) Analysis of the residue will be as follows: (1) If the residue is less than 0.0025 g, the material is acceptable without further analysis. (2) If residue is 0.0025 g or more, the procedure shown in 4.2.1.1)(a) will be repeated and the residue analyzed in accordance with ASTM D 129 or ASTM D 1552. (3) Alternately, the material may be decomposed in accordance with ASTM D 129 and analyzed in accordance with ASTM D 516 Method B. (4) The sulfur content must not exceed 1% of the residue by weight. 2) When examining austinetic stainless steel or titanium, all materials must be analyzed individually for chlorine and fluorine content as follows: (a) An individual sample of penetrant materials with the exception of cleaners will be prepared for analysis by heating 50 g of the material in a 150 mm nominal diameter glass Petri dish at a temperature of 194°F to 212°F for 60 minutes. (b) Analysis of the residue will be as follows: (1) If the residue is less than 0.0025 g, the material is acceptable without further analysis. (2) If the residue is 0.0025 g or more, the procedure showing 4.2.1.2)(a) will be repeated and the residue analyzed in accordance with ASTM D 808 or SE-165 Annex 2 for chlorine and SE-165 Annex for fluorine. (3) The chlorine plus fluorine content must not exceed 1% of the residue by weight. (c) An individual sample of the cleaner / remover material will be prepared for analysis by heating 100 g of the material in a 150 mm nominal diameter Petri dish at a temperature of 194°F to 212°F for 60 minutes.
