ASTM F2073-14 薄膜开关无损短路检验的标准试验方法

3.1 Destructive and non-destructive tests characteristics must be evaluated to ensure the membrane switch will operate and survive the application it was designed for. It is not feasible for all tests to be performed on each membrane of a production lot. However, there are some non-destructive tests that must be performed on each switch assembly to ensure 1008201;% functionality and checking each i/o point for unwanted electrical continuity to any other i/o point is one of these characteristics. 1.1 This standard establishes a test method for detecting unwanted electrical shorts in a membrane switch. 1.2 Since this is a non-destructive test, it can be performed on a membrane switch that is going to be mounted and used in its intended environment. 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 F2866-10 定义组装中膜开关的易燃性的标准测试方法

There are numerous flammability ratings and tests. Almost without fail, these standards and tests are focused on very specific industries or results, many of which are not applicable to the membrane switch/human machine interface assembly. This test is designed to provide relative results between membrane switches that have been assembled to the unit''s final enclosure, housing, etc. In addition to the test''s measurement of the rate of burn, a laboratory can also observe the effects of burning material falling from the test specimen onto other materials (typically a gauze test area) not directly part of the test specimen. The indirect burning is an issue of interest to see if the test specimen will be able to act as an initiator for a far greater and more damaging flame event (fire). Observations should be noted, as qualitative descriptions, as appropriate. This test can measure the flammability via the use of high-speed photographic or video equipment. Temperature of the ignition source can be measured via a calibrated thermocouple pyrometer, calorimeter or IR thermometer with an appropriate range. This test is not designed to provide a PASS or NO PASS status for a switch, rather, it is designed to provide a “grade” for the level of flammability of a membrane switch assembly (as defined in 3.1.10). The end user should make the final determination if the level of flammability is acceptable for the particular application.1.1 This test method covers the determination of the flammability characteristics of a membrane switch. 1.2 This test method defines the MSB rating of a membrane switch. Each character of the MSB rating represents a discrete characteristic of a membrane switch performance under destructive thermal loading. 1.3 This test procedure will be destructive, but should provide an insight into the relative performance flame-resistance characteristics of differing designs or assemblies, or both. 1.4 This test method will focus on the use of convective contact (burner flame) method for ignition, though other methods of ignition are available. 1.5 This test method is designed to determine if the membrane switch assembly will add (or detract) from the flame propagation from an exterior flame/fire source. 1.6 If this test is intended to be used for an internal flammability source then set up the unit under test (UUT) appropriately and note it in the test scope and results. 1.7 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.

Standard Test Method for Flammability of a Membrane Switch in Defined Assembly

ASTM F1895-10 膜片开关的浸没规程

The presence of water inside a membrane switch can affect its mechanical operation or electrical functionality, or both. Electrical failure can result as short circuits due to silver migration or exceeding the specified resistance due to oxidation. This test method establishes a procedure to verify the ability of a membrane switch to resist the entry of liquid in itself or a finished product, or both. It is useful in identifying design deficiencies. Submersion testing may be destructive, therefore any samples tested should be considered unfit for future use.1.1 This test method establishes procedures for the submerging of a membrane switch to verify resistance to ingress of a specified liquid. 1.2 This test method can also be used to verify the ability of a membrane switch or graphics layer to act as a liquid seal for a finished product. 1.3 Additional test methods or practices can be incorporated to investigate specific results or capabilities. 1.4 This test method is a modification of National Electrical Manufacturers Assoc. (NEMA) Publication 250-1991 Section 6.10, which is a test for submersion of a finished product housing. 1.5 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. 1.6 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.

Electromechanical switches for use in electrical and electronic equipment - Part 1: Generic specification

ASTM F2360-08(2015)e1 测定漫射光源的薄膜开关背光亮度的标准试验方法

3.1 Illumination of a switch or of certain features of a switch often has a functional purpose and must meet specification to satisfy the functional requirements of the switch. 3.2 Illumination of the switch can be affected by variations in the quality and design of the overlay and its application. 3.3 This test method addresses only the optical and visual appearance of the switch and not its electrical function. 3.4 This test method is non-destructive. 3.5 If this test method is applied to the entire switch assembly, the results can be applied to the whole device. However, it may be sufficient and practical to apply the test either to a subassembly only, or to the illumination layer only, in which case the results apply to that layer only and the net effect on the fully assembled device must be calculated, extrapolated, or otherwise inferred. 1.1 This test method covers procedures for determining the luminance of a backlit membrane switch. As written, it applies to a fully assembled switch. For specific purposes, it can be applied to partially assembled switches with the understanding that the results pertain only to the partial assembly and will be modified as the further assembly proceeds. 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Determining Luminance of a Membrane Switch Backlit with Diffuse Light Source

ASTM F1596-07 薄膜开关暴露于温度和相对湿度的标准试验方法

Changes in temperature and humidity during shipping, storage or use can affect the visual appearance, mechanical integrity, or electrical functionality of switches. This practice simulates three different environments to which membrane switches may be exposed. The three industry-recognized switch categories based on performance levels are Level 1, Level 2, and Level 3 (see section 8.1). Additionally, there may be custom requirements that vary by application, therefore, these requirements can be determined by customer and vendor agreement and be established as a Level 4. This practice defines the duration of a single cycle. Multiple cycles may be appropriate depending on the requirements of the application.^SCOPE: 1.1 This test method covers a procedure for temperature and humidity cycling of membrane switches. 1.2 This test method is performed to evaluate the properties of materials used in the construction of membrane switch assemblies as they are influenced by the absorption and diffusion of moisture and moisture vapor. This is an accelerated environmental test, accomplished by the continuous exposure of the test specimen to high relative humidity at an elevated temperature. Absorption of moisture by many materials results in swelling, which destroys their functional utility, causes loss of physical strength, and changes in other mechanical properties. Insulating materials which absorb moisture may suffer degradation of their electrical properties. 1.2.1 Physical changes: 1.2.1.1 Differential contraction or expansion rates or induced strain of dissimilar materials. 1.2.1.2. Cracking of surface coatings. 1.2.1.3 Leaking of sealed compartments. 1.2.1.4 Deformation or fracture of components. 1.2.2 Chemical changes: 1.2.2.1 Separation of constituents. 1.2.2.2 Failure of chemical agent protection. 1.2.3 Electrical changes: 1.2.3.1 Changes in electronic and electrical components. 1.2.3.2 Electronic or mechanical failures due to rapid water of condensate formation. 1.2.3.3 Excessive static electricity. 1.3 This test method is not intended to be a thermal shock procedure; a ramp rate between temperature extremes should not exceed 2°C/min. 1.4 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.

Fastener Code Revision 29

ASTM F1578-07 薄膜开关的接触闭合循环用标准试验方法

This testing is performed to determine the electrical contact reliability under switching conditions and the physical changes caused by mechanical actuation of the switch assembly in the environments in which the assemblies operate. Evidence of deterioration, that is, cracking of substrate, domes both metal and polyester, ink delamination, etc., resulting from this test can at times be determined by visual examination. However, the effects may be more readily ascertained by measurements made prior to, during, and after exposure. Total circuit resistance, force-displacement, dielectric strength, insulation resistance, and capacitance are types of measurements that show the deleterious effects due to exposure.1.1 This test method covers the setup, procedure, and apparatus required to depress and release a membrane switch to a predetermined number of cycles. 1.2 This test method also covers the optional use of specified voltage and current during the cycling of the membrane switch. 1.3 This test method can be used in conjunction with other ASTM standards such as Test Method F 1596. 1.4 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.

Standard Test Method for Contact Closure Cycling of a Membrane Switch

ASTM F1997-07 触觉薄膜开关敏感度的测定(针拨开法)用标准试验方法

The tendency of a switch to make or break electrical contact at unexpected moments during closure or release can be a sign of a poor design. The degree of teasing can range from a simple annoyance to a failure of critical control process. The amount of switch sensitivity or teasing can also be a result of poor surface conductivity that will prevent an electrical event even when switch poles are in partial contact.1.1 This test method establishes procedures for depressing and releasing a tactile membrane switch to determine the amount of switch teasing, if any. 1.2 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.
