It is difficult to rinse the astk traces of chlorine from the walls of the bomb and the tendency for residual chlorine to carry over from sample to sample has been observed in a number of laboratories. This is generally accomplished through the use of a properly designed spray booth and exhaust system.
Developing time begins immediately after the application of dry powder developer or as soon as the wet aqueous or nonaqueous developer coating is dry that is, the water or solvent carrier has evaporated to dryness.
For this purpose there must be a separate code, standard, or a specific agreement to define the type, size, location, and direction of indications considered acceptable, and those considered unacceptable. Some solid additives are relatively insoluble, but qstm be satisfactorily burned when covered with a layer of white oil. They can also be dusted with the powder developer through a hand powder bulb xstm a conventional or electrostatic powder gun.
It provides a single instrumental technique for rapid, sequential measurement of common anions such as bromide, chloride,? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Quantitation is by measurement of peak area or peak height. Blanks are prepared and analyzed in a similar fashion.
Care should be taken not to contaminate the developer with? Contact time shall be kept e16509 the minimum time to obtain an acceptable background and shall not exceed three minutes. All of these contaminants can prevent the penetrant from entering discontinuities see Annex on Cleaning of Parts and Materials. Both types of solvent paint removers are generally used at ambient temperatures, as received.
Agreement by the customer requesting penetrant inspection is strongly recommended. The actual time required in the vapor degreaser and solvent soak will depend on the nature of the part and should be determined experimentally. A minimum light intensity at the examination surface of fc [ lx] is required see Guide E for more information.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For this purpose there must be a separate code, standard, or a specific agreement to define the type, size, location, and direction of indications considered acceptable, and those considered unacceptable. We are ready to help you with your non-destructive testing needs.
Your Alert Profile lists the documents that will be monitored. Adjust detector to desired setting usually 10? Active view current version e165-009 standard. The length of time the penetrant must remain on the part to allow proper penetration should be as recommended by the penetrant manufacturer. For this purpose there must be a separate code, standard, or a speci? Coil the middle section about 20 mm and attach the free ends to the terminals.

Solvent cleaners are not recommended for the removal of rust and scale, welding? It should be used with water and detergent if the soil to be removed is inorganic rust, dirt, salts, corrosion products, etc. Aerosol sprays are conveniently portable and suitable for local application. Some cleaning solvents are?
Both conventional and electrostatic qstm guns are effective means of applying liquid penetrants to the part surfaces. Immerse the parts only long enough to coat all of the part surfaces with the developer since indications may leach out if the parts are left in the bath too long.
Agreement by the customer requesting penetrant inspection is strongly recommended.
Wash down the walls of the bomb shell with a? Chromate interferes with the procedures, causing low or nonexistent end points.
Proper illumination is required to ensure adequate sensitivity of the examination. Care should be taken to only use bulbs suitable for? If traces of unburned oil or sooty deposits are found, discard the determination, and thoroughly clean the bomb before again putting it in use. Room temperature drying can be aided by the use of fans. The total rinse time shall not exceed two minutes regardless of the number of rinse methods used.
Recalibrate whenever the detector setting is changed. This procedure will remove all but very deep pits and put a high polish on the surface. In some cases, it is desirable to vapor degrease, then follow with a solvent soak.
Remove the bomb from the bath after immersion for at least 10 min. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Cleaning time should be as recommended by the manufacturer of the cleaning compound.
