Core Standards

This specification covers round, aluminum-clad steel core wire used for mechanical reinforcement in the manufacture of aluminum conductors, aluminum-clad steel reinforced. The base metal shall be steel produced by the openhearth, electric-furnace, or basic-oxygen process and shall be of such...

The objective of this glossary is to establish uniform definitions of parts and terminology for engine cooling systems. Components included are all those through which engine coolant is circulated: water pump, engine oil cooler, transmission and other coolant-oil coolers, charge air coolers,...

This specification covers coextruded poly(vinyl chloride) plastic pipe with a cellular core and concentric inner and outer solid layers. The pipe is produced using a multilayer coextrusion die for nonpressure use in three series: an IPS Schedule 40 series; a PS series with an iron pipe size...

4.1 Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of an anode block. 4.1.1 Test specimen obtained by this guide can be used by producers and users of carbon anodes for the purpose of conducting the tests in Note 1 to obtain comparative...

4.1 Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of a cathode block. 4.1.1 Test specimens obtained by this guide can be used by producers and users of cathode blocks for the purpose of conducting the tests in Note 1 to obtain comparative...

5.1 The procedures described in this practice have proven utility in the inspecting (1) monolithic polymer matrix composites (laminates) for bulk defects, (2) metals for corrosion during the service life of the part of interest, (3) thickness checks, (4) adhesive bonding of metals, composites, and...

5.1 Tests performed at the same location across a span of years may be used to detect a reduction of infiltration rate of the pervious concrete, thereby identifying the need for remediation. 5.2 The infiltration rate obtained by this method is valid only for the localized area of the pavement where...

This standard covers the general requirements and methods for testing sandwich core materials and for testing sandwich construction of the types used primarily in aircraft structures. This standard does not include test methods applicable only to a specific product; such test methods are...

5.1 This test was developed to mimic the formation of insolubles observed in some heavy-duty diesel cooling systems during the mid 1980s. It measures the compatibility of SCA and coolant concentrate solutions according to their tendency to form insolubles in service.3 Such insoluble materials may...

This specification covers expanded honeycomb core made of glass cloth impregnated with polyimide resin and supplied in the form of blocks, slices, and ordered shapes.

This specification covers honeycomb core made of glass fabric impregnated with phenolic resin and supplied in the form of blocks, slices, and ordered shapes.

1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 (3/4 hard), 1350-H14 or -H24 (1/2 hard) and 1350-H142 or -H242 (1/2 hard) bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electrical conductors or in covered...

This specification covers coextruded acrylonitrile-butadiene-styrene (ABS) plastic drain, waste, and vent pipes made to Schedule 40 iron pipe sizes (IPS) with concentric inner and outer solid ABS layers and a closed-cell cellular ABS core. The ABS plastics used to make the pipes shall only...

1.1 These four test methods cover the determination of the strength of intact rock core specimens in uniaxial and triaxial compression. Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. 1.2...

4.1 Regulatory Requirements-The USA Code of Federal Regulations (10CFR Part 50, Appendix H) requires the implementation of a reactor vessel materials surveillance program for all operating LWRs. Other countries have similar regulations. The purpose of the program is to (1) monitor changes in the...

This specification covers the general requirements for faced thermal insulation boards composed of rigid cellular polyisocyanurate surfaced with other materials. This standard is intended to apply to rigid cellular polyurethane-modified polyisocyanurate thermal insulation board products that are...
