ASTM C871-18(2023)(Test Method)
Standard Test Methods for Chemical Analysis of Thermal Insulation Materials for Leachable Chloride, Fluoride, Silicate, and Sodium Ions

SIGNIFICANCE AND USE
5.1 Research has demonstrated that in addition to the halide ion chloride; fluoride ions, when deposited and concentrated on the surface of austenitic stainless steel, can contribute to external stress corrosion cracking (ESCC) in the absence of inhibiting ions.5 Two widely used insulation specifications that are specific to ESCC allow the use of the same Test Methods C692 and C871 for evaluation of insulation materials. Both specifications require fluoride ions to be included with chloride ions when evaluating the extractable ions.  
5.2 Chlorides (and fluorides) can be constituents of the insulating material or of the environment, or both. Moisture in the insulation or from the environment can cause chlorides (and fluorides) to migrate through the insulation and concentrate at the hot stainless steel surface.  
5.3 The presence of sodium and silicate ions in the insulation has been found to inhibit external stress corrosion cracking caused by chloride (and fluoride) ions, whether such ions come from the insulation itself or from external sources. Furthermore, if the ratio of sodium and silicate ions to chloride (and fluoride) ions is in a certain proportion in the insulation, external stress corrosion cracking as a result of the presence of chloride (and fluoride) in the insulation will be prevented or at least mitigated (see also Specification C795).
SCOPE
1.1 These test methods cover laboratory procedures for the determination of water-leachable chloride, fluoride, silicate, and sodium ions in thermal insulation materials in the parts per million range.  
1.2 Selection of one of the test methods listed for each of the ionic determinations required shall be made on the basis of laboratory capability and availability of the required equipment and appropriateness to the concentration of the ion and any possible ion interferences in the extraction solution.  
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.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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 C692-13(2023)(Test Method)
Standard Test Method for Evaluating the Influence of Thermal Insulations on External Stress Corrosion Cracking Tendency of Austenitic Stainless Steel

SIGNIFICANCE AND USE
5.1 An inherent characteristic of some alloys of austenitic stainless steel is their tendency to crack at stress points when exposed to certain corrosive environments. The mechanisms of ESCC are complex and not completely understood but are apparently related to certain metallurgical properties. Chloride and fluoride ions have the potential to induce stress corrosion cracking in the absence of inhibiting ions.3  
5.2 Chlorides are common to many environments, so great care shall be taken to protect austenitic stainless steel from chloride contamination.  
5.3 Most thermal insulations will not, of themselves, cause stress corrosion cracking. Preproduction qualification tests are used to evaluate that under the conditions of the laboratory test that specific thermal insulation materials do not cause cracking of sensitized austenitic stainless steel. Insulation systems have the potential to act as collecting media by means of transmigration and concentration of corrosive ions on heated stainless steel surfaces. Exposure to elevated temperature results in evaporation of water and increased chemical reaction rates. Environments containing corrosive ions, moisture, and oxygen will increase the chance for stress corrosion cracking.  
5.4 Insulation materials are available that are specially formulated to inhibit stress corrosion cracking in the presence of chlorides through modifications in basic composition or incorporation of certain chemical additives.  
5.5 The ability of the 28-day test to measure the corrosion potential of insulation materials is documented by Karnes,4 whose data appear to have been used for construction of the acceptability curve used in Specification C795 and other specifications.  
5.6 The metal for all of the coupons used in this test method (C692) shall be qualified (see Section 14) to ascertain that under conditions of the test, chloride ions will cause the metal to crack, and deionized water alone will not cause cracks.
SCOPE
1.1 This test method covers two procedures for the laboratory evaluation of thermal insulation materials to determine whether they contribute to external stress corrosion cracking (ESCC) of austenitic stainless steel due to soluble chlorides within the insulation. This laboratory procedure is not intended to cover all of the possible field conditions that contribute to ESCC.  
1.2 While the 1977 edition of this test method (Dana test) is applicable only to wicking-type insulations, the procedures in this edition are intended to be applicable to all insulating materials, including cements, some of which disintegrate when tested in accordance with the 1977 edition. Wicking insulations are materials that wet through and through when partially (50 % to 75 %) immersed in water for a short period of time (10 min or less).  
1.3 These procedures are intended primarily as a preproduction test for qualification of the basic chemical composition of a particular manufacturer's product and are not intended to be routine tests for ongoing quality assurance or production lot compliance. Test Methods C871, on the other hand, is used for confirmation of acceptable chemical properties of subsequent lots of insulation previously found acceptable by this test method.  
1.4 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.  
1.5 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.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Dev...

Standard Test Method for Measuring Non-Fibrous Content of Man-Made Rock and Slag Mineral Fiber Insulation

SIGNIFICANCE AND USE
4.1 Inorganic fibrous thermal insulation can contain varying amounts of non-fibrous material. Non-fibrous material does not contribute to the insulating value of the insulation and therefore a procedure for determining that amount is desirable. Several specifications refer to shot content and percent (%) retained on various screen sizes determined by this test method.
SCOPE
1.1 This test method covers a procedure for determining the non-fibrous content (shot) of man-made rock and slag mineral fiber insulation. The procedure covers a dry sieve analysis method to distinguish between fiberized and non-fiberized (shot) portions of a specimen of man-made rock and slag mineral fiber insulation specimen.  
1.2 This test method does not apply to rock or slag materials containing any components other than rock and slag mineral fiber, oil, and organic thermal setting binders. Products containing other types of fibers, inorganic binders, or refractory clays are excluded.
Note 1: Industrial oils such as mineral or synthetic can be used to enhance the hydrophobic qualities and dust suppression.  
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.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

Standard Specification for Cellular Melamine Thermal and Sound-Absorbing Insulation

ABSTRACT
This specification covers cellular melamine thermal and sound-absorbing insulation for use in industrial environments operating within the specified temperature range. Some applications of the thermal insulation materials covered by this standard are subject to building codes for fire performance. A vapor retarder is required when the insulation materials are used for cold surface applications where water vapor condense and may cause a decrease in thermal performance. Open-cell melamine foam is produced when a pentane blowing agent is used to foam a melamine-aldehyde precondensate. Melamine thermal insulation is furnished in three types according to shape and two grades according to facing. The typical facing materials are aluminum foil, aluminized mylar, polyvinylchloride, and polyvinylfluoride. All materials should conform to the required values of oxygen index, specific optical smoke density, surface burning characteristics, density, tensile strength, percent elongation, indentation force deflection, and thermal conductivity.
SCOPE
1.1 This specification covers the type, physical properties, and dimensions of open-cell melamine foam intended for use as thermal and sound-absorbing insulation for temperatures from −40 to +350°F (−40 to +177°C) in industrial environments.  
1.2 Some uses of thermal insulation materials covered by this specification are governed by building codes that address fire performance.  
1.3 The use of an appropriate vapor retarder is required on cold surface applications where water vapor condense and cause a decrease in thermal performance. Refer to Practice C755 for selection of vapor retarders. Facings shall be agreed upon between the purchaser and the manufacturer or supplier.  
1.4 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.  
1.5 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.  
1.6 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 C335/C335M-23(Test Method)
Standard Test Method for Steady-State Heat Transfer Properties of Pipe Insulation

SIGNIFICANCE AND USE
4.1 As determined by this test method, the pipe insulation lineal thermal resistance or conductance (and, when applicable, the thermal resistivity or conductivity) are means of comparing insulations which include the effects of the insulation and its fit upon the pipe, circumferential and longitudinal jointing, and variations in construction, but do not include the effects of the outer surface resistance or heat transfer coefficient. They are thus appropriate when the insulation outer-surface temperature and the pipe temperature are known or specified. However, since the thermal properties determined by this test method include the effects of fit and jointing, they are not true material properties. Therefore, properties determined by this test method are somewhat different from those obtained on apparently similar material in flat form using the guarded hot plate, Test Method C177, or the heat flow meter apparatus, Test Method C518.  
4.2 The pipe insulation lineal thermal transference incorporates both the effect of the insulation and its fit upon the pipe and also the effect of the surface heat-transfer coefficient. It is appropriate when the ambient conditions and the pipe temperature are known or specified and the thermal effects of the surface are to be included.  
4.3 Because of the test condition requirements prescribed in this test method, recognize that the thermal transfer properties obtained will not necessarily be the value pertaining under all service conditions. As an example, this test method provides that the thermal properties shall be obtained by tests on dry or conditioned specimens, while such conditions are not necessarily realized in service. The results obtained are strictly applicable only for the conditions of test and for the product construction tested, and must not be applied without proper adjustment when the material is used at other conditions, such as mean temperatures that differ appreciably from those of the test. With these quali...
SCOPE
1.1 This test method covers the measurement of the steady-state heat transfer properties of pipe insulations. Specimen types include rigid, flexible, and loose fill; homogeneous and nonhomogeneous; isotropic and nonisotropic; circular or non-circular cross section. Measurement of metallic reflective insulation and mass insulations with metal jackets or other elements of high axial conductance is included; however, additional precautions must be taken and specified special procedures must be followed.  
1.2 The test apparatus for this purpose is a guarded-end or calibrated-end pipe apparatus. The guarded-end apparatus is a primary (or absolute) method. The guarded-end method is comparable, but not identical to ISO 8497. The ISO method does not use the calculation procedure in Practice C1045.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 When appropriate, or as required by specifications or other test methods, the following thermal transfer properties for the specimen can be calculated from the measured data (see 3.2):  
1.4.1 The pipe insulation lineal thermal resistance and conductance,  
1.4.2 The pipe insulation lineal thermal transference,  
1.4.3 The surface areal resistance and heat transfer coefficient,  
1.4.4 The thermal resistivity and conductivity,  
1.4.5 The areal thermal resistance and conductance, and  
1.4.6 The areal thermal transference.
Note 1: In this test method the preferred resistance, conductance, and transference are the lineal values computed for a unit length of pipe. These must not be confused with the corresponding areal properties computed on a unit area basis which are more applicable to flat slab geometr...

ASTM C1374-18(2023)(Test Method)
Standard Test Method for Determination of Installed Thickness of Pneumatically Applied Loose-Fill Building Insulation

SIGNIFICANCE AND USE
5.1 This test method was designed to give the manufacturer of loose-fill insulation products a way of determining what the initial installed thickness should be in a horizontal open attic for pneumatic applications.  
5.2 The installed thickness value developed by this test method is intended to provide guidance to the installer in order to achieve a minimum mass/unit area for a given R-value.  
5.3 For the purpose of product design, testing should be done at a variety of R-values. At least three R-values should be used: the lowest R-value on the product label, the highest R-value on the product label, and an R-value near the midpoint of the R-value range.
Note 1: For quality control purposes, testing may be done at one R-value of R-19 (h×ft 2×°F/Btu) or higher.  
5.4 Specimens are blown in a manner consistent with the intended installation procedure. Blowing machine settings should be representative of those typically used for field application with that machine.  
5.5 The material blown for a given R-value as part of the installed thickness test equals the installed mass/unit area times the test chamber area. This mass can be calculated from information provided on the package label at the R-value prescribed.
SCOPE
1.1 This test method covers determination of the installed thickness of pneumatically applied loose-fill building insulations prior to settling by simulating an open attic with horizontal blown applications.  
1.2 This test method is a laboratory procedure for use by manufacturers of loose-fill insulation for product design, label development, and quality control testing. The apparatus used produces installed thickness results at a given mass/unit area.  
1.3 This test method is not the same as the design density procedures described in Test Methods C520 or Specifications C739 or C764.  
1.4 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.  
1.5 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.  
1.6 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.
