This specification covers packaged, dry, cementitious mortar or concrete materials for rapid repairs to hardened hydraulic-cement concrete pavements and structures. Materials that contain organic compounds, such as bitumens, epoxy resins, and polyesters, as the principal binder are not included. Packaged, dry, concrete material contains aggregate of which at least 5% by mass of the total mixture is retained. Packaged, dry, mortar material contains aggregate of which less than 5% by mass of the total mixture is retained. Aqueous solutions, aqueous emulsions or dispersions may be included as components of the packaged materials. Aggregates must be included as a component of the packaged materials. Both packaged dry concrete and mortar shall be mechanically mixed with the use of a mixing liquid. Different test methods shall be performed in order to determine the following properties: compressive strength, length change, scaling resistance, and slant shear bond strength.

This practice describes the general ultrasonic examination procedures for the detection of discontinuities in the weld and adjacent heat affected zones of welded pipe and tubing by scanning with relative motion between the search unit and pipe or tube. When contact or unfocused immersion search units are employed, this practice is intended for tubular products having specified outside diameters and wall thicknesses. And when properly focused immersion search units are employed, this practice may also be applied to material of smaller diameter and thinner wall. This practice does not establish acceptance criteria for this procedure. A pulsed ultrasonic angle beam shall be propagated in the wall of the pipe or tube by either the surface contact or immersion method. The weld line shall then be examined from both sides to ensure detection of imperfections with a shape or orientation that produces a preferential direction of reflection.

This standard specification describes four categories of two-stroke-cycle gasoline engine lubricants based on their miscibility with gasoline and their low-temperature fluidity. The lubricant categories are classified according to the temperature at which the tests are conducted. The lubricants shall meet the requirements for viscosity and miscibility with gasoline. Miscibility test method shall be done using a rotator, graduated cylinders, stoppered flask, and freezer, and shall use reference oil and any full-boiling-range gasoline as indicated in the specification. Fluidity test method shall be done using Brookfield viscometer and its associated equipment. All test method shall be in accordance with the calibration and standardization procedure indicated in the specification.

This specification covers requirements of precision (Class A) and general purpose (Class B) grade glass measuring pipets used for volume measurement of liquids. Pipets covered by this specification may be of the standard taper tip type (Style 1) or of the long taper tip type (Style 2), which is only available for Class B pipets, and are available in nine different capacities. The pipet shall be manufactured from annealed borosilicate glass into a straight, one-piece construction that is free of defects which may distort the appearance of the liquid surface. The pipets shall be marked wit permanent and legible graduation lines lying in a plane perpendicular to the vertical axis of the pipet by etching the glass and filling the etched area with a permanent pigment, by etching through a vertical colored stripe fused into the glass, by applying a stain fired into the glass without etching, or by applying an enamel fired into the glass without etching. In addition, the pipet shall also be color coded with one or two color bands. Pipets shall undergo testing such as specified for reusable laboratory glassware.

This specification covers the requirements for precision grade glass volumetric flasks for laboratories and specialty use. The products can be grouped into three styles according to size and shape. All products should be calibrated and should conform to the required shapes, volumetric tolerances, identification markings, capacity lines, quality of markings, and quality of laboratory marking spots.

This specification covers wildcats as used in windlasses to haul in and pay out anchor chain on board ships. Wildcats shall be classified based on materials and manufacture. Wildcats shall be fabricated from structural steel plate, medium-strength carbon steel castings, or high-strength steel castings, joined by electric welding. Wildcats shall conform to specified dimensions, depending on chain size. Wildcats shall be tested to fit sample chain. Workmanship, finish, appearance, packaging, and making shall conform to the requirements of this specification.

This specification covers the design and dimensional requirements for metallic, ceramic, and polymeric mating bearing surfaces used in total hip joint prostheses and hip endoprostheses, more specifically, hip joint replacements of the ball-and-socket configuration. This specification covers the sphericity, surface finish requirements, and dimensional tolerances for the following: spherical articulating metallic or ceramic femoral heads of total hip joint prostheses; spherical concave mating surface of metallic and ceramic acetabular components, including the inner polymeric bearing surface of bipolar heads; spherical concave mating surface of polymeric acetabular components; and spherical metallic or ceramic femoral heads of hip endoprostheses, and the outer bearing surface of bipolar heads. This specification, however, does not address the tolerance match between the mating bearing surfaces.

This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both. Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application. These insulation resistance monitors shall be classified in four types: Type I are alternating current generator monitors, Type II are alternating current generator monitors, Type III are direct current motor monitors, and Type IV are direct current generator monitors. The enclosure materials used in the construction of the monitors are to be flame-retardant and the current carrying terminals shall be made of corrosion resistant material. The monitors shall isolate their measuring circuit from the line voltage, while the motor is operating, by the use of an integral isolating relay. In the design of these monitors, environmental factors shall be considered: operating temperature range, sealing, inclination, humidity, and vibration. Also, the monitor relays, voltage characteristics and operating accuracy shall be considered in the design of these monitors. Each monitor shall be subjected to the following: visual and mechanical examination and operational test.

This specification covers precast concrete barriers intended for use adjacent to a roadway or as a median to redirect vehicles unintentionally leaving the roadway. The acceptance criteria for these barriers shall be based on strength properties, dimensional properties, and end results. Conformance as to materials (cement, aggregates, admixtures, and steel reinforcements), design (concrete strength, air entrainment, dimensions, steel reinforcements, concrete finish, lifting devices, anchorage, and reinforcement laps, welds, and splicing), and manufacture (mixture, accelerated curing, water curing, membrane curing, and forms) should be observed precisely. Physical requirements shall be examined by compression, curing compression, and core compression tests.
