1.1 This test method covers and is intended as a rapid method for the evaluation of the oxidation stability of new mineral insulating oils containing a synthetic oxidation inhibitor. This test is considered of value in checking the oxidation stability of new mineral insulating oils containing 2,6-ditertiary-butyl para-cresol or 2,6-ditertiary-butyl phenol, or both, in order to control the continuity of this property from shipment to shipment. The applicability of this procedure for use with inhibited mineral insulating oils of more than 12 cSt at 40 °C (approximately 65 SUS at 100 °F) has not been established.1.2 The values stated in SI units are to be regarded as standard except where there is no direct equivalent for hardware designed on the inch-pound unit basis.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. (See warning in 6.7.)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.

5.1 Petrographic examinations are made for the following purposes:5.1.1 To determine the mineralogy of the material that may be observed by petrographic methods (in this method, by use of XRD) and that may have a bearing on the performance of the material in its intended use.5.1.2 To determine the relative amounts of the constituents of the sample which is essential for proper evaluation of the sample when the constituents may differ significantly in properties that have a bearing on the performance of the material in its intended use.5.1.3 This method helps to evaluate mineral aggregate sources for suitability as a material to be used for construction, renovation, or modification of equine surfaces. The information gathered will allow for the comparison of the composition of new mineral sources with samples of other mineral aggregate from one or more sources, for which test data or performance records are available.5.2 This method may be used by a petrographer employed directly by those for whom the examination is made. The employer should tell the petrographer, in as much detail as necessary, the purposes and objectives of the examination, the kind of information needed, and the extent of examination desired. Pertinent background information, including results of prior testing, should be made available. The petrographer’s advice and judgment should be sought regarding the extent of the examination.5.3 This method may form the basis for establishing arrangements between a purchaser of consulting petrographic service and the petrographer. In such a case, the purchaser and the consultant should together determine the kind, extent, and objectives of the examination and analyses to be made and should record their agreement in writing. The agreement may stipulate specific determinations to be made, observations to be reported, funds to be obligated, or a combination of these or other conditions.1.1 X-Ray diffraction (XRD) is a tool for identifying minerals, such as quartz and feldspar, and types of clay present in bulk samples of equine surfaces. Determining the mineralogy of a given bulk sample provides insight into surface properties, such as abrasion resistance by comparing the relative differences of hardness of the various mineral fractions such as quartz or feldspar or the plasticity differences in clay minerals such as smectite or kaolinite. XRD techniques are qualitative in nature and only semi-quantitative.1.2 Particle size distribution analyses methods including hydrometer tests to determine proportions of sand, silt, and clay fractions based upon particle size but are not able to distinguish particles by shape or mineralogy of materials. In addition to a qualitative detection of minerals present in a sample, XRD methods are also semi-quantitative and also yield important data on the relative proportion of particular minerals present.1.3 XRD techniques are generally semi-quantitative in nature. Even so, such semiquantitative data is useful in determining relative proportions of each mineral type. This method is also semi-qualitative in nature as it is geared for the determination or mineral groups. For example, it will determine the relative amount of alkali feldspars (such as K-feldspar or Nafeldspar) from Plagioclase-feldspar but not necessarily if the Plagioclase-feldspar is albite or anorthite nor whether the K-feldspar is orthoclase of microcline. Likewise, it will differentiate smectite from mica from kaolinite but not whether the smectite is montmorillonite or saponite. More precise determination of mineral species by XRD is possible but involves more advanced preparation and treatment methods than what is within the scope of this standard.1.4 The XRD method herein primarily makes use of “Glass Slide Method” but may be subject to modification depending on the user’s needs.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.

This specification covers perpendicularly oriented mineral fiber roll and sheet thermal insulation for use on the flat, curved, or round surfaces of pipes and tanks. The orientation of the rock, slag, or glass fibers within the roll or sheet insulation is essentially perpendicular to the heated/cooled surface. Materials covered in this specification do not include flat block, board, duct wrap, or preformed pipe mineral fiber insulation where the insulation fiber orientation is generally parallel to the heated/cooled surface. In low-temperature applications, properly installed protective vapor retarders should be used to prevent water vapor from moving through or around the insulation towards the colder surface. The materials are classified into six types according to the maximum use temperature and maximum apparent thermal conductivity and into two categories according to minimum compressive resistance. Samples taken from the materials should be tested according to the recommended procedures and should conform to the required values of corrosiveness to steel, stress corrosion to austenitic stainless steel, shot content, maximum use temperature, maximum exothermic temperature rise, and compressive resistance.1.1 This specification covers the composition, dimensions, and physical properties of compression-resistant, perpendicularly oriented mineral fiber (rock, slag, or glass) roll and sheet insulation intended for use on flat, curved, or round surfaces operating at temperatures between 0°F (–18°C) and 1000°F (538°C). This product (pipe and tank insulation) is typically used on nominal 24 in. (610 mm) or greater diameter surfaces. For specific applications, the actual use temperatures and diameters shall be agreed upon between the manufacturer and the purchaser.1.2 The orientation of the fibers within the roll or sheet insulation is essentially perpendicular to the heated/cooled surface (parallel to heat flow). This specification does not apply to flat block, board, duct wrap, or preformed pipe mineral fiber insulation where the insulation fiber orientation is generally parallel to the heated/cooled surface (across the heat flow).1.3 For satisfactory performance, properly installed protective vapor retarders must be used in 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 retarders properties are not part of this specification, properties required in Specification C1136 are pertinent to application or performance.1.4 When the installation or use of thermal materials, accessories, and systems may pose safety or health problems, the manufacturer shall provide the user-appropriate current information regarding any known problems associated with the recommended use for the products of the company and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 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 specification describes a high fire-point mineral oil based electrical insulating fluid, for use as a dielectric and cooling medium in new and existing power and distribution electrical apparatuses, such as transformers and switchgear. The material discussed here is miscible with other petroleum based insulating oils, and may not be miscible with electrical insulating liquids of non-petroleum origin. The insulating oils shall be compatible with typical material of construction of existing apparatus and will satisfactorily maintain its functional characteristic in its application. This specification applies only to new insulating material oil as received prior to any processing. Sampled specimens shall undergo appropriate tests, and shall conform correspondingly to specified physical (appearance upon visual examination, color in ASTM units, fire point, flash point, aniline point, interfacial tension, pour point, relative density, and kinematic viscosity), electrical (dielectric breakdown voltage, gassing tendency, and dissipation factor), and chemical (corrosion behavior against sulfur, inorganic chlorides and sulfates content, acid number, water content, oxidation stability, oxidation inhibitor content, and PCB content) property requirements.1.1 This specification describes a less flammable mineral electrical insulating liquid, for use as a dielectric and cooling medium in new and existing power and distribution electrical apparatus, such as transformers and switchgear.1.2 Less flammable insulating liquid differs from conventional mineral insulating liquid by possessing a fire-point of at least 300 °C. This property is necessary in order to comply with certain application requirements of the National Electrical Code (Article 450-23) or other agencies. The material discussed in this specification is miscible with other petroleum based insulating liquids. Mixing less flammable liquids with lower fire point hydrocarbon insulating liquids (for example, Specification D3487 mineral liquid) may result in fire points of less than 300 °C.1.3 This specification is intended to define a less flammable electrical mineral insulating liquid that is compatible with typical material of construction of existing apparatus and will satisfactorily maintain its functional characteristic in this application. The material described in this specification may not be miscible with electrical insulating liquids of non-petroleum origin. The user should contact the manufacturer of the less flammable insulating liquid for guidance in this respect.1.4 This specification applies only to new electrical insulating liquid as received prior to any processing. Information on in-service maintenance testing is available in appropriate guides.2 The user should contact the manufacturers of the equipment or liquid if questions of recommended characteristics or maintenance procedures arise.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

5.1 Particles in insulating oil can have a detrimental effect on the dielectric properties of the fluid, depending on the size, concentration, and nature of the particles. The source of these particles can be external contaminants, oil degradation by-products, or internal materials such as metals, carbon, or cellulose fibers.5.2 Particle counts provide a general degree of contamination level and may be useful in assessing the condition of specific types of electrical equipment. Particle counts can also be used to determine filtering effectiveness when processing oil.5.3 If more specific knowledge of the nature of the particles is needed, other tests such as metals analysis or fiber identification and counting must be performed.1.1 This test method covers the determination of particle concentration and particle size distribution in mineral insulating oil. It is suitable for testing oils having a viscosity of 6 mm2/s to 20 mm2/s at 40 °C. The test method is specific to liquid automatic particle analyzers that use the light extinction principle.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.
