The resistance of corrugated fiberboard shipping containers to damage by moisture is improved by wax treatment, and a common practice involves a light wax saturation applied to the medium and facings, followed by a curtain coating or roll coating operation applying wax to the surface. The functional performance of the board is dependent upon the amount of wax deposited in each operation.5.1.1 For the wax impregnation within the facing, the principal concern is with the weight of wax used relative to the weight of paperboard present, that is, the weight percent loading or pickup. This method measures that loading and assumes that the loading is distributed uniformly throughout the facing. However, the method does not provide a measure of the weight of impregnating wax per unit area, since not all of the facing fibers are utilized in the testing.5.1.2 For the wax coating the principal concern is in the weight of wax present on the surface per unit area. This method measures the amount of material applied, and assumes that the major portion of molten coating applied will congeal and remain on the surface, without undue migration into the fibrous structure of the medium.Note 2—In a typical curtain coating application, a portion of the coating will partially migrate into and become embedded in the fibers of the facing to the extent of about 10 % of the coating applied.5.1.3 These procedures involve extractions of designated sections of the paperboard and determination of the extractable material reported as wax. This assumes that the nonwax extractables in the paperboard substrate are in negligible amount (for example, about 0.2 weight %).Note 3—If the application of a correction for nonwax extractables is desired, a suitable unwaxed board specimen may be extracted and appropriate calculations made.1.1 This test method covers the determination of the weight of wax that has been applied for coating of corrugated board, and the amount of impregnating (saturating) wax in the same facing.1.2 This test method is especially applicable to board that has a coated surface and also contains wax saturation within the facing structure. Note 1 - The amount of surface wax on board that may or may not contain impregnating (saturating) wax within its structure may be determined alternatively by Test Method D 3521. If it is known that the specimen has coating wax only, with no internal impregnating wax, the total coating wax applied may be determined by Test Method D 3344.<>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.

4.1 The procedures described in this practice are intended to be used to establish design capacity (both strength and stiffness) values based on testing of OSB that, at a minimum, satisfies the relevant performance requirements of PS 2.4.2 Review and reassessment of values derived from this practice shall be conducted on a periodic basis. If a change is found to be significant, retesting or reevaluation, or both, in accordance with the procedures of this practice shall be considered.1.1 This practice covers the basis for code recognition of design capacities for OSB structural-use panels. Procedures are provided to establish or re-evaluate design capacities for OSB structural-use panels in flatwise and axial applications. Design capacities for OSB structural-use panels in edgewise applications, such as rim board, are outside the scope of this standard. Procedures for sampling and testing are also provided. Design values stated as capacity per unit dimension are to be regarded as standard. Design capacities developed in accordance with this practice are applicable to panels intended for use in dry in-service conditions.NOTE 1: This practice is based on ICC-ES Acceptance Criteria AC-182. Relative to the scope of AC-182, this practice is limited to OSB panels.NOTE 2: While this practice makes reference to PS 2, this practice applies similarly to products certified to other standards such as CAN/CSA O325.NOTE 3: OSB produced under PS 2 is rated with the “Exposure 1” bond classification. Exposure 1 panels covered by PS 2 are intended for dry use applications where the in-service equilibrium moisture content conditions are expected to be less than 16 %. Exposure 1 panels are intended to resist the effects of moisture due to construction delays, or other conditions of similar severity. Guidelines on use of OSB are available from manufacturers and qualified agencies.NOTE 4: PS 2-10 replaced the use of nominal thicknesses with a classification term known as Performance Category, which is defined in PS 2 as “A panel designation related to the panel thickness range that is linked to the nominal panel thickness designations used in the International Building Code (IBC) and International Residential Code (IRC).” Therefore, the PS 2 Performance Category should be considered equivalent to the term “nominal thickness” used within this standard.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 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 mineral fiber block and board thermal insulation. Mineral fiber board insulation covered by this specification shall be classified into types and categories; category 1 - no compressive resistance properties are required, category 2 - minimum compressive resistance properties are required, type V, grade A - requires no heat-up schedule, type V, grade B - heat-up schedule is required. Mineral fiber block and semi-rigid and rigid board insulation shall be composed of rock, slag, or glass processed from the molten state into fibrous form and bonded with organic or inorganic binders or both. A detectable odor of objectionable nature recorded by more than two of five panel members shall constitute rejection. When tested and evaluated, the corrosion resulting from insulation in contact with steel plates shall be judged to be no greater than for comparative plates in contact with sterile cotton. When tested and evaluated at its delivered thickness, all mineral fiber (rock, slag, and glass) board and block must qualify to be semi-rigid or rigid. When tested, the board and block insulation shall not warp, flame, or glow during hot surface exposure. When tested, the midpoint temperature shall not at any time exceed the hot surface temperature by more than 200°F (111°C). Determine the thermal conductivity as a function of temperature for the representative specimens with data obtained from a series of thermal tests. The compressive resistance, linear shrinkage, water vapour sorption, odor emission, and rigidity or semi-rigidity shall be tested to meet the requirements prescribed.1.1 This specification covers the classification, composition, dimension, and physical properties of mineral fiber (rock, slag, or glass) semi-rigid and rigid board intended for the use as thermal insulation on surfaces operating at temperatures between 0°F (-18°C) and 1800°F (982°C). For specific applications, the actual temperature limits shall be agreed upon between the supplier and the purchaser.1.2 For satisfactory performance, properly installed protective vapor retarder or barriers shall be used on below ambient temperature applications to reduce movement of water through or around the insulation towards the colder surface.

5.1 This test method provides a way to detect contamination on printed wiring board fingers that affects the electrical performance of such fingers. Such contamination may arise during PWB manufacture, circuit assembly, or service life and may include solder mask, solder flux, hardened lubricants, dust, or other materials. This test method provides a nondestructive method of inspecting such fingers at any point in the life of the product including after original manufacture, after assembly of circuit components to the PWB, and after time in service such as when returned for repair. Because this test method uses two probes to finger contacts in series, it provides a sensitive test for contaminants that may increase electrical resistance when the fingers are plugged into an edgecard connector that typically makes contact to the finger through only one contact to finger interface.5.2 Practice B667 describes a more general procedure for measuring contact resistance of any solid material in practically any geometrical form. The method in Practice B667 should be used for general studies and fundamental studies of electrical contact materials.1.1 This test method defines a resistance probing test for detecting the presence of foreign matter on Printed Wiring Board (PWB) contacts or fingers that adversely affects electrical performance.
