Linpin Salt Spray Climate chambers can meet the GM4298P standard, pls refer the main point of the GM4298P standard showed as below.
1.Scope
GM4298P standard covers the requirements necessary to attain the conditions found in a neutral salt spray test cabinet.
1.1 The chamber operation is based on ASTM B117 with the following clarifications.
1.2 The salt spray test is better suited for quality control and process control evaluations. Other tests may be better suited to simulate field performance.
3 Preparation of test specimens
3.1 The methods of application, film thickness, curing and conditioning of the test surface shall be as specified. consistent with the normal production practices (cleaning, pretreatment, etc.).
3.2 The backs, cut edges of plated, coated, or duplex materials and those areas containing identification marks or in contact with racks or supports shall be protected with a suit coating that is stable under the condition of the test.
3.3 Specimens shall be suitably cleaned. The cleaning method shall be optional depending on the nature of the surface and the contaminants. The cleaning shall not include the.use of abrasives, other than a paste of pure magnesium oxide, nor of solvents which are corrosive or that will deposit either corrosive or protective films. Care shall be taken that specimens are not contaminated after cleaning by excessive or careless handling.
3.4 Specimens for evaluation of paints and other organic coatings shall be prepared according to applicable specifications for the material being tested.
3.5 Whenever it is desirable to determine the development of corrosion from an abraded area in the paint or organic coating a scratch or described line shall be made through the coating as described in GM9102P.
4 Temperature
4.1 The temperature within the exposure zone of the closed chamber shall be maintained @ 35 ± 2℃ and recorded continuously throughout the test duration by an external recorder.
6 Test solution
6.1 The salt solution shall be prepared by dissolving 5 g± 1 g of salt (NaCL) to 95 mL of water as described in 5.1. The salt used shall be of reapent grade. A solution having a specific gravity of 1.0255 to 1.0400 is required.
6.2 The pH of the collected solution must be in the pH range of 6.5 to 7.2. The pH of the collected solution shall be checked and recorded daily. Readings on weekends need not be taken.The pH measurement shall be made electronically using a glass electrode with a saturated potassium chloride bridge (mild agitation is recommended). The pH of the collected solution will be higher than the pH of the original solution due to the loss of carbon dioxide at the higher temperature. The H of the make up solution may be adjusted with the addition of small amounts of hydrochloric acid (HCD or sodium hydroxide (NaOH2) solution.
6.3 Specific gravity of the collected solution shall be 1.0255 0400 when measured at 25℃.
7 Atomization and quality of fog
7.1 Chest type cabinets require 1 fog collector for every 0.55 square meter (6 square feet) of test area. The larger walk in type test cabinets require 1 fog collector for every 1.40 square meter (15 square feet). The collectors must be placed within the exposure zone so that no drops of solution from the test specimens or any other source shall enter collectors. The collectors shall be placed in the proximity of the test specimens and at the same height as the test specimens. Collectors shall be evenly distributed to produce a representative measure of the fog collection rates throughout the chamber. The fog shall be such that for each 80 cm? ( approximately 10 cm diameter) of horizontal test area there will be 1.0 to 2.0 ml of fog per in collected in each collector. This rate of collection shall be based on a minimum run of at least 16 h.
7.2 Chambers must demonstrate compliance to all parameters prior to placing samples in test. At least 24 h of cabinet operation would be required prior to test sample exposure. Mapping must be performed after any major change or at least yearly.
7.3 Collection rate mapping of a chamber throughout the exposure zone, to ensure conformance to the collection rate requirement is required as a means of reducing test variability.
7.4 Air pressure and temperature at the humidifying tower shall conform to Appendix X1.4 of ASTM B117.
8 Continuity of test
81 Test interruptions should be limited to a maximum of 3 in any 24 h period. The duration of any single interruption shall be limited to a maximum of 10 minutes. If a special test is being run which requires longer or more frequent interruptions, that test shall not be run simultaneously in the same chamber with any other test Collections must be evaluated and recorded daily. (Weekends and holidays are exceptions).
10 Safety
This method may involve hazardous male rials, operations and equipment This method does not propose to address all the safety issues associated with its use. It is the responsibility of the user of this method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
