Standard Test Method for Thermal Shock Resistance of Porcelain-Enameled Utensils

Standard Test Method for Thermal Shock Resistance of Porcelain-Enameled Utensils

ABSTRACT
This test method covers the determination of the resistance of porcelain-enameled utensils to thermal shock. A hot plate, timing device, container, and sponge shall be used. The surface temperature of the hot plate, determined by any suitable surface temperature measuring device, may be varied by changing the wattage input to the hot plate. If the hot plate surface temperature be calibrated to wattage input, the desired temperature may then be set by adjusting wattage input. The wattage input or similar calibration shall be made for each surface temperature. In preparation for the test, the hot plate shall be leveled and the surface temperature shall be adjusted to a certain level. Quenching water shall be placed in a large container and its temperature shall be adjusted to a certain level. The amount of water required to fill a test utensil to a certain depth shall be measured. A dry utensil shall be centered directly on the preheated hot plate. After a certain time, the utensil shall be removed from the hot plate and the utensil immediately shall be filled to some depth with quenching water. After a few seconds, the quenching water shall be poured out and the inside of the utensil shall be wiped with a wrung-out damp sponge. After some time, the utensil on the hot plate shall be replaced. Immediately after centering the utensil on the hot plate, the input to the hot plate shall be adjusted so that the hot plate surface temperature will reach a certain level. The utensil shall be allowed to heat dry for a few minutes with the hot plate adjusted so the new surface temperature will be reached. After a certain heating period, the utensil shall be removed. This procedure shall be repeated according to the schedule given. The test shall be continued until the utensil fails or has withstood quenching after a certain heating temperature.
SCOPE
1.1 This test method covers the determination of the resistance of porcelain-enameled utensils to thermal shock. This test method is adaptable to any porcelain-enamel utensil that can be filled with water to a depth of 1 in. (25 mm).  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

ASTM C536-83(2023)(Test Method)
Standard Test Method for Continuity of Coatings in Glassed Steel Equipment by Electrical Testing

SIGNIFICANCE AND USE
4.1 This test method is designed to detect existing discontinuities in the glass coating of glassed steel equipment while maintaining a voltage low enough as to be unlikely to cause breakdown of the coating. The test is adaptable for manufacturing inspection in the processing of equipment and for field use to find existing defects which can be “plugged” or repaired before serious damage is done to the equipment. As a means of positive detection, it is applicable to process studies, quality control, or specification.
SCOPE
1.1 This test method covers the detection of discontinuities in the glass coating of glassed steel equipment where such discontinuities would result in early failure due to the attack of the chemical contents of the vessel on the metal substrate. It is applicable to (1) provide a manufacturing and inspection test of glassed-steel equipment designed for relatively mild, low-temperature corrosive service, and (2) the field testing of similar equipment used in more severely corrosive environment.
Note 1: A manufacturing test method for the latter type of equipment is described in Test Method C537.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C537-87(2023)(Test Method)
Standard Test Method for Reliability of Glass Coatings on Glassed Steel Reaction Equipment by High Voltage

SIGNIFICANCE AND USE
4.1 The widespread use of glassed-steel equipment in highly corrosive chemical processes has made it necessary to detect weak spots in the coating and repair them before catastrophic failure occurs in service. This test is intended to detect discontinuities and thin areas in a glass coating on metal to ensure that the coating is defect free and has sufficient thickness to withstand the prescribed service conditions. A test voltage may be selected at any desired value up to 20k V, thus making the test applicable to a wide range of thickness requirements. When, because of bubbles or defects, the thickness of glass at any spot is less than enough to withstand the applied voltage, a puncture results with an accompanying indication of a defect. Remedial action is then required to repair the defect before the equipment can be used for corrosive service. (When such defects are found before the equipment leaves the manufacturer's plant another application of glass can usually be applied and fired to become an integral part of the coating.)
SCOPE
1.1 This test method covers the determination of the reliability of glass coating on metal and is intended for use by manufacturers of equipment that is designed to withstand highly corrosive conditions where a failure of the coating in service would cause extreme damage to the exposed metal. Its use outside the manufacturer's plant is discouraged because improper or indiscriminate testing can cause punctures that are difficult to repair without returning the equipment to the manufacturer's plant. This test method detects not only existing discontinuities in the glass coating, but also areas where the glass may be thin enough to be likely to result in premature failure in service.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 7.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This test method covers the determination of the resistance of porcelain-enameled utensils to thermal shock. A hot plate, timing device, container, and sponge shall be used. The surface temperature of the hot plate, determined by any suitable surface temperature measuring device, may be varied by changing the wattage input to the hot plate. If the hot plate surface temperature be calibrated to wattage input, the desired temperature may then be set by adjusting wattage input. The wattage input or similar calibration shall be made for each surface temperature. In preparation for the test, the hot plate shall be leveled and the surface temperature shall be adjusted to a certain level. Quenching water shall be placed in a large container and its temperature shall be adjusted to a certain level. The amount of water required to fill a test utensil to a certain depth shall be measured. A dry utensil shall be centered directly on the preheated hot plate. After a certain time, the utensil shall be removed from the hot plate and the utensil immediately shall be filled to some depth with quenching water. After a few seconds, the quenching water shall be poured out and the inside of the utensil shall be wiped with a wrung-out damp sponge. After some time, the utensil on the hot plate shall be replaced. Immediately after centering the utensil on the hot plate, the input to the hot plate shall be adjusted so that the hot plate surface temperature will reach a certain level. The utensil shall be allowed to heat dry for a few minutes with the hot plate adjusted so the new surface temperature will be reached. After a certain heating period, the utensil shall be removed.

Standard Test Method for Adherence of Porcelain Enamel Coatings to Sheet Metal

SIGNIFICANCE AND USE
2.1 The measurement of adherence in porcelain enamel systems, such as ground coat, ground coat/cover coat, and direct-on cover-coat enamels, is an important procedure for monitoring process variables in metal preparation, enamel application thickness, steel selection, and enamel selection, as well as assuring the ultimate quality of the finished product.
SCOPE
1.1 The scope of this test method is:  
1.1.1 To determine quantitatively the amount of enamel remaining after the porcelain enamel coating specimen has been deformed;  
1.1.2 To standardize the deformation parameters for testing adherence of porcelain enamel to sheet metal; and,  
1.1.3 To provide a quantitative adherence rating scale for comparison to reference standards.  
1.2 This adherence test method is applicable to porcelain enamel coatings on substrates from 18 to 24 gauge (0.0478 to 0.025 in. or from 1.214 to 0.654 mm).  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Standard Test Methods for Spalling Resistance of Porcelain Enameled Aluminum

SIGNIFICANCE AND USE
3.1 It is difficult to overemphasize the importance of the spall test. Porcelain enameled aluminum that fails this test will probably spall in service if subjected to moisture or weathering.
SCOPE
1.1 These test methods cover accelerated determination of the resistance of porcelain enamel coatings on aluminum alloys to spalling from exposure to moisture or weathering. Test Method A,2 using a 5 % solution of ammonium chloride, requires 96-h immersion while Test Method B,3 using a 1 % solution of antimony trichloride, is completed after 20 h of immersion. The spalling tendency is evaluated by the same criteria in both methods. While either method is suitable for magnesium silicon alloys, such as 6061, Test Method B is preferred for simple alloys or commercially pure aluminum, such as 1100.  
1.2 The test methods appear in the following order:    
Sections  
Test Method A—Ammonium Chloride  
4 – 9  
Test Method B—Antimony Trichloride  
10 – 15
