Standard Test Methods for Mastics and Coatings Used With Thermal Insulation

ABSTRACT
These test methods cover procedures for sampling and testing mastics and coatings for use as weather and vapour barrier finishes on thermal insulations and for other accessory use. Take the samples for laboratory examination from the original containers immediately after stirring to a uniform condition. Determine the number of containers sampled as required representing a shipment. Open the original containers and examine them for uniformity of contents. The procedures for determining the stability of coatings under freezing are presented in details. The paper covers the determination of the volume of volatile matter and the coverage per unit of dry film thickness of mastics and coatings. Application of the material to the test panels shall meet the requirements prescribed, or to the thickness and by the method to be followed in practice, such as spray, brush, or trowel. Test the coated panel prepared in accordance with the required method at 15-min intervals to determine the time required to set-to-touch, and at 30-min intervals to determine the time to reach practical hardness.
SCOPE
1.1 These test methods cover procedures for sampling and testing mastics and coatings for use as weather and vapor retarder finishes on thermal insulations and for other accessory use.  
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.

Standard Test Method for Conducting Exterior Exposure Tests of Finishes for Thermal Insulation

SIGNIFICANCE AND USE
5.1 Both physical and chemical changes possibly occur from weather exposure, and these changes affect performance properties, service life, and maintenance schedules. For this reason, tests of properties relating to performance shall be made both before and after specific periods of outdoor exposure.  
5.2 This test method recognizes that differing geographical locations, environmental conditions, differences between surface temperatures and ambient temperatures, and test durations have extremely varied effects upon the test results.  
5.3 This test method is to be used for comparative qualitative testing.
SCOPE
1.1 This test method covers out-of-doors exposure testing of finishes that are normally field-applied to thermal insulation and possibly include joints or joint sealants, or both. Such exposure is essential prior to the determination of certain physical properties when the finish is to be exposed to exterior weather conditions. This test method also indicates possible compatibility problems between the joint sealant and the finish as well as the ability of the finish to span a dry joint. This test method is not intended to evaluate mildew resistance, efflorescence, or chemical resistance.

Standard Specification for Mineral-Fiber Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing

ABSTRACT
This specification covers the composition and physical properties of mineral-fiber blanket insulation used to thermally or acoustically insulate ceilings, floors, and walls in light frame construction and manufactured housing. The requirements cover fibrous blankets and facings. Typical mineral-fiber thermal insulation is classified into the following types, classes, and categories: Type I; Type II (Class A, Class B, and Class C (Category 1 and Category 2)); and Type III (Class A, Class B, and Class C (Category 1 and Category 2)). The following test methods shall be performed: dimensions; thermal resistance; surface burning characteristics; critical radiant flux; water vapor permeance; water vapor sorption; odor emission; corrosiveness; and fungi resistance.
SIGNIFICANCE AND USE
11.1 This specification applies to products that are used in buildings. While products that comply with this specification are used in various constructions, they are adaptable primarily, but not exclusively, to wood frame construction.  
11.2 Since the property of thermal resistance for a specific thickness of blanket is only part of the total thermal performance of a building element such as a wall, ceiling, floor, and so forth, this specification states only general classifications for thermal resistance of the fibrous blanket itself. Facings that provide additional resistance to water-vapor transfer can affect system performance.
SCOPE
1.1 This specification covers the composition and physical properties of mineral-fiber blanket insulation used to thermally or acoustically insulate ceilings, floors, and walls in light frame construction and manufactured housing. The requirements cover fibrous blankets and facings. Values for water-vapor permeance of facings are suggested for information that will be helpful to designers and installers.  
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, 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 C686-17(2023)(Test Method)
Standard Test Method for Parting Strength of Mineral Fiber Batt- and Blanket-Type Insulation

SIGNIFICANCE AND USE
3.1 Tensile strength is a fundamental property associated with mineral fiber manufacture since it is influenced by the type of fiber, the deposition of fiber, the type and the amount of bonding agent, and the method of curing the resin to form a bonded insulation product. The test is an indication of product integrity and the ability of the product to be successfully handled and applied in the field.
SCOPE
1.1 This test method covers evaluation of strength in tension on mineral fiber batt- and blanket-type insulation products. It is useful for determining the comparative tensile properties of these products, specimens of which cannot be held by the more conventional clamp-type grips. This is a quality control method, and the results shall not be used for design purposes. It is not suitable for board-type products.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Water Retention of Rigid Thermal Insulations Following Partial Immersion

SIGNIFICANCE AND USE
4.1 Materials less than or equal to 15 mm (0.59 in.) in thickness shall not be tested in accordance with this test method in order to avoid complete immersion of the specimens. This type of exposure is beyond the scope of this test method.  
4.2 This test method is used to assess both the short-term water retention and the long-term water retention. The short-term water retention is assessed as the average of the water retained following partial immersion intervals of 0.75-h and 3.00-h, in kilograms per square meter (percent by volume) (for materials tested at 25.4 mm (1.00 in.) thickness). The long-term water retention is assessed as the water retained following a 168-h partial immersion interval, in kilograms per square meter (percent by volume) (for materials tested at 25.4 mm (1.00 in.) thickness).  
4.3 Materials shall be tested at both actual product thickness and 25.4 mm (1.00 in.) thickness provided the materials can be cut to a thickness of 25.4 mm (1.00 in.) without changing the original character of the materials. If a product cannot be cut without changing the original character of the material, the corresponding information shall be provided in the test report. Results shall be reported on the basis of equal nominal wetted specimen surface area (in units of kilograms per square meter) for materials tested at actual product thickness and on the basis of equal specimen volume (in units of percent by volume) for materials tested at 25.4 mm (1.00 in.) thickness. If a product cannot be cut to a thickness of 25.4 mm (1.00 in.) or if the actual product thickness is less than 25.4 mm (1.00 in.) but greater than 15 mm (0.59 in.), the product shall only be tested at actual product thickness and results only reported on the basis of equal nominal wetted specimen surface area.  
4.3.1 By reporting results on the basis of equal nominal wetted specimen surface area, specimens of different thicknesses can be compared equitably. For some specimens, the water intake ...
SCOPE
1.1 This test method determines the amount of water retained (including surface water) by rigid block and board thermal insulations used in building construction applications after these materials have been partially immersed in liquid water for prescribed time intervals under isothermal conditions. This test method is intended to be used for the characterization of materials in the laboratory. It is not intended to simulate any particular environmental condition potentially encountered in building construction applications.  
1.2 This test method does not address all the possible mechanisms of water intake and retention and related phenomena for rigid thermal insulations. It relates only to those conditions outlined in 1.1. Determination of moisture accumulation in thermal insulations due to complete immersion, water vapor transmission, internal condensation, freeze-thaw cycling, or a combination of these effects requires different test procedures.  
1.3 Each partial immersion interval is followed by a brief free-drainage period. This test method does not address or attempt to quantify the drainage characteristics of materials. Therefore, results for materials with different internal structure and porosity, such as cellular materials and fibrous materials, are not necessarily directly comparable. Also, test results for specimens of different thickness are not necessarily directly comparable because of porosity effects. The surface characteristics of a material also affect drainage. It is possible that specimens with rough surfaces will retain more surface water than specimens with smooth surfaces, and that surface treatment during specimen preparation will affect water intake and retention. Therefore, it is not advisable to directly compare results for materials with different surface characteristics.  
1.4 For most materials the size of the test specimens is small compared with the size of the products actually inst...

Standard Specification for Prefabricated Reflective Insulation Systems for Equipment and Pipe Operating at Temperatures above Ambient Air

ABSTRACT
This specification covers the standard for all metal prefabricated, reflective insulation systems for equipment and piping operating at temperatures above ambient in air proposed for use in nuclear power-generating plants and industrial plants. The insulation unit is a rigid, self-contained, prefabricated metal construction made of an inner and outer casing arranged to form a rigid assembly with separated air spaces between the inner and outer casing and the individual reflective liners. The reflective insulation described herein is limited to systems of insulating units, designed to fit the equipment or piping to be insulated. The units shall be manufactured from metals that are in accordance with the thermal, physical, and chemical requirements not only of the insulation as unit, but also as an assembly of units forming the insulation system.
SCOPE
1.1 This specification covers the requirements for all metal prefabricated, reflective insulation systems for equipment and piping operating in air at temperatures above ambient. Typical applications are in nuclear power-generating plants and industrial plants.  
1.2 Reflective insulation is thermal insulation that reduces radiant heat transfer across spaces by the use of surfaces of high reflectance and low emittance.  
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 Mineral Fiber Blanket Insulation and Blanket-Type Pipe Insulation (Metal-Mesh Covered) (Industrial Type)

ABSTRACT
This specification covers mineral fiber blanket insulation and blanket-type pipe insulation (metal-mesh covered) (industrial type). Mineral fiber metal-mesh covered blanket shall be composed of rock, slag, or glass processed from the molten state into fibrous form, bonded with or without an organic binder, and secured with metallic supporting facing(s). Types of facings for one or both sides of blanket units shall be specified. When both sides are to be faced, units are permitted to have the same or different types on the two sides. Each piece of metal-mesh covered insulation shall be coherent to permit handling/transportation and installation as a unit. A detectable odor of objectionable nature recorded by more than two of the five panel members shall constitute rejection of the material. When tested and evaluated, the corrosion resulting from the unfaced insulation blanket in contact with metal plates shall be judged to be no greater than comparative plates in contact with sterile cotton. The averaged maximum shot content of mineral fiber rock or slag type products shall not exceed 30 % by weight. When tested, the blanket insulation shall not warp, flame, or glow during hot surface exposure. When tested, the blanket mid-point temperature shall not at any time exceed the hot surface temperature by more than 100°F (55.5°C). When tested, the blanket insulation shall not exceed the recorded temperature rise more than 54°F (30°C) with no flaming and weight loss exceeding 5 %.
SCOPE
1.1 This specification covers the composition, dimensions, and physical properties of mineral fiber (rock, slag, or glass) metal mesh covered and industrial type blanket and blanket-type pipe insulation (typically on 24 in. (610 mm) diameters or larger)). Its use is for cooled surfaces at temperatures operating below ambient to 0°F (−18°C) and on heated surfaces on expansion joints to large diameter vessels and tanks operating at temperatures up to 1200°F (649°C). Specific applications outside the actual use temperatures shall be agreed upon between the manufacturer and purchaser.  
1.2 For satisfactory performance, properly installed protective vapor retarders or barriers shall be used on below ambient temperature applications to reduce movement of moisture/water vapor through or around the insulation towards the colder surface. Failure to use a vapor retarder can lead to insulation and system damage. Refer to Practice C921 to aid material selection. Although vapor retarder properties are not part of this specification, properties required in Specification C1136 are pertinent to applications or performance.  
1.3 The orientation of the fibers within the blanket is primarily parallel to the heated surface. This specification does not cover fabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide fiber orientation that is perpendicular to the heated surface.  
1.4 This standard does not purport to provide the performance requirements of hourly-rated fire systems. Consult the manufacturer for the appropriate system.  
1.5 See Supplementary Requirements for modifications to sections in this standard only when specified by purchaser in the contract or order from the U.S. Military specifications utilized by the U.S. Department of Defense, Department of the Navy, and the Naval Systems Command.  
1.6 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.  
1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Inner and Outer Diameters of Thermal Insulation for Nominal Sizes of Pipe and Tubing

SIGNIFICANCE AND USE
4.1 The purpose of this practice is to ensure satisfactory fit on standard sizes, to accommodate radial expansion of pipes and tubes which are heated after being insulated, and to minimize the number of insulation sizes and thicknesses to be manufactured and stocked.  
4.2 While it is possible to manufacturer insulation to these recommended dimensions, exercise care in attempting to nest layers of different materials, or layers supplied by different manufacturers. Individual manufacturing processes will operate at slightly different tolerances. While the product will fit the pipe, it is possible that it will not readily nest as the outer layer between the different materials, or with a different manufacturer, and possibly the same manufacturer. Exercise care to determine these differences before specifying or ordering nesting sizes.  
4.3 The wide range of outer diameter dimensional tolerances will prevent many pipe and tube insulations from nesting for staggered joints or double layered applications, or both unless specified when ordered from the manufacturer, distributor, or fabricator.  
4.4 Dimensions in accordance with this practice do not necessarily permit application of one thickness of pipe insulation over another (Nesting or Simplified Dimensional System) to obtain total thicknesses greater than those manufactured as single layer, or for multilayer application when desired.

SCOPE
1.1 This practice is intended as a dimensional standard for preformed thermal insulation for pipes and tubing.  
1.2 This practice covers insulation supplied in cylindrical sections and lists recommended single layer inner and outer diameters of insulation having nominal wall thicknesses from 1/2 to 5 in. (13 to 127 mm) to fit over standard sizes of pipe and tubing.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values stated in SI units are provided for information only.  
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.
