Scope. This drawing describes the specific electrical, mechanical, and environmental requirements and specifications for tantalum hybrid capacitors, hermetically sealed in welded tantalum case with glass to metal anode terminal.

This test method covers screening procedures for the preliminary evaluation of leak-stopping materials intended for use in engine cooling systems. (Heavy-duty users are referred to X1.2.21 in Specification D4485 for additional information.) The values stated in SI units are to be regarded as...

This test method measures the ability of crankcase oil to control camshaft lobe wear for spark-ignition engines equipped with an overhead valve-train and sliding cam followers. This test method is designed to simulate extended engine idling vehicle operation. The Sequence IVA Test Method uses a...

This test method, commonly referred to as the L-37-1 test, describes a test procedure for evaluating the load-carrying capacity, wear performance, and extreme pressure properties of a gear lubricant in a hypoid axle under conditions of low-speed, high-torque operation.3 The values stated in SI...

This test method covers the determination of benzene, toluene, ethylbenzene, the xylenes, C9 and heavier aromatics, and total aromatics in finished motor gasoline by gas chromatography. The aromatic hydrocarbons are separated without interferences from other hydrocarbons in finished gasoline....

The test method covers a heavy-duty engine test procedure under high output conditions to evaluate engine oil performance with regard to piston deposit formation, piston ring sticking and oil consumption control in a combustion environment designed to minimize exhaust emissions. This test method is...

This test method describes a procedure to measure shear strength development for adhesives used to bond resilient flooring and carpet to selected substrates. This test method provides a quantitative means of measuring and recording shear strength of the adhesive when it is applied to the desired...

This test method covers the determination of apparent specific gravity (Sections 5 to 9) and true specific gravity (Sections 10 to 14) of lump coke larger than 25 mm [1 in.] size and calculating porosity (Section 15) from the specific gravity data. Units-The values stated in either SI units or...

This practice applies to the blending of automotive spark-ignition engine fuels with ethanol concentrations greater than those suitable for conventional-fuel vehicles and less than the minimum ethanol content specification limits of Specification D5798. These mid-level ethanol fuel blends are for...

This specification covers poly(vinyl chloride) (PVC) Schedule 40 pipe fittings. Included are requirements for materials, workmanship, dimensions, and burst pressure. NOTE 1-Socket-type CPVC plastic pipe fittings, Schedule 40, which were formerly included in this standard, are now covered by...

This specification (see Note 1) covers grades of fuel oil intended for use in various types of fuel-oil-burning equipment under various climatic and operating conditions. These grades are described as follows: Grades No. 1 S5000, No. 1 S500, No. 1 S15, No. 2 S5000, No. 2 S500, and No. 2 S15 are...

This specification covers additives for aviation fuels (for example, Specifications D910, D7547, and D1655) used to inhibit ice formation in aircraft fuel systems. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard....

Test Method A covers the determination of carbon in the range of 54.9 % to 84.7 %, hydrogen in the range of 3.26 % to 5.08 %, and nitrogen in the range of 0.57 % to 1.76 % in analysis samples (8.1) of coal and of carbon in analysis samples of coke in the range of 86.6 % to 97.9 %. Test Method B...
