Standard Specification for Laboratory Glass Graduated Cylinders
Abstract: This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. The graduated cylinders may be in one of three styles; beaded lip with spout, grounded standard ... -
Standard Test Method for Comparing the Brightness of Fluorescent Penetrants
Abstract: 5.1 The principle use of this procedure is for the comparison of the brightness between batches of fluorescent penetrants compared to a specified standard, as a batch quality control test. 5.2 The procedure is also utilized ... -
Standard Specification for Thermostat Metal Sheet and Strip
Abstract: This specification covers the standard for thermostat metals in the form of sheet or strip proposed for use as temperature-sensitive elements of devices for controlling, compensating, or indicating temperature. Metals shall ... -
Standard Test Method for Field Measurement of Sound Power Level by the Two-Surface Method
Abstract: 5.1 The function and operation of equipment in the field often preclude the measurement of the free-field sound pressure levels of a single piece of equipment in the absence of interfering sound from other equipment operating ... -
Standard Practice for Ammonia Colorimetric Leak Testing
Abstract: 6.1 This method is useful for locating and measuring the size of gas leaks either as a quality-control test or as a field-inspection procedure. It can be used to test critical parts or containers that will hold toxic or ... -
Standard Specification for Thermocouple Connectors
Abstract: 4.1 The widespread use of thermocouple connectors requires standardization of mating dimensions and performance characteristics. 4.2 This specification describes standardized thermocouple connector dimensions and capabilities ... -
Standard Test Methods for Deglazing Force of Fenestration Products
Abstract: 4.1 Under normal usage, deglazing loads are generally applied parallel to the plane of the glazing material and eccentric to the sash element when it is opened, closed, or lifted out of the frame. When operating hardware ... -
Standard Specification for Glass Volumetric (Transfer) Pipets
Abstract: This specification covers volumetric pipets of two classes. Class A, Precision Pipet and Class B, General Purpose. Borosilicate glass for pipets shall conform to the glass requirements specified. Pipets shall be calibrated ... -
Standard Specification for Factory-Made Wrought Aluminum and Aluminum-Alloy Welding Fittings
Abstract: This specification covers only factory-made wrought aluminum and aluminum-alloy welding fittings in contrast to field-made fittings. The aluminum or aluminum-alloy material used in the manufacture of the fittings shall be ... -
Standard Specification for Glass Westergren Tube, Reusable
Abstract: This specification covers the design and dimensional requirements for reusable glass Westergren tubes that measure the erythrocyte sedimentation rate (ESR), which is the suspension stability, or amount of settling after a ... -
Standard Specification for Interchangeable Taper-Ground Stopcocks And Stoppers
Abstract: The specification provides the standard dimensional requirements for obtaining, within practical limits, interchangeability in stopcocks and stoppers for ordinary laboratory and industrial applications. It solely covers ... -
Standard Specification for Commercially Packaged Laboratory Apparatus
Abstract: This specification covers the procedures for testing loaded shipping containers. Drop and vibration tests are performed to measure the ability of the shipping container to protect the product from the shock and vibration ... -
Standard Specification for Pipet, Blood Diluting
Abstract: This specification covers the requirements for glass reusable blood diluting pipets that are used for performing red and white cell corpuscle determinations. The pipets shall be made of common spirit bore white back tubing ... -
Standard Test Method for Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials
Abstract: 5.1 This test method is useful for estimating the strain at the onset of necking in a uniaxial tension test (1). Practically, it provides an empirical parameter for appraising the relative stretch formability of similar ... -
Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Cyclic Static Air Pressure Difference
Abstract: 5.1 This test method is a standard procedure for determining the resistance to water penetration under cyclic static air pressure differences. The air-pressure differences acting across a building envelope vary greatly. ... -
Standard Test Method for Testing Side Force Friction on Paved Surfaces Using the Mu-Meter
Abstract: 4.1 The knowledge of side force friction serves as an additional tool in characterizing pavement surfaces. Side force friction data alone may be of limited value in determining the suitability of paving materials or finishing ... -
Standard Test Method for Calibrating a Wheel Force or Torque Transducer Using a Calibration Platform (User Level)
Abstract: 5.1 Wheel force or torque transducers are used under dynamic test conditions, and the measurements are subject to many error sources. The static calibration recommended by the present standard cannot eliminate all error ... -
Standard Specification for Disposable Glass Micropipets
Abstract: This specification covers two different types of disposable glass micropipets, calibrated “to contain,” used in measuring microlitre volumes of liquids. The pipets made to these specifications shall be fabricated from ... -
