This specification covers the establishment of the minimum requirements for the design, testing, and quality assurance of fixed-pitch or ground adjustable propellers for light sport aircraft. The propeller may not have design features that have been shown to be hazardous or unreliable unless the suitability of each questionable design detail or part can be established by tests. Strength testing; stress measurement, fatigue strength, and fatigue analysis, endurance testing, and teardown inspection shall be performed to meet the requirements prescribed.

This specification covers poly(vinyl chloride)(PVC) and other conforming organic polymer-coated steel barbed wire consisting of two polymer-coated strands, with four-point barbs of zinc-coated steel or aluminum alloy wire used with chain-link fence. PVC and other organic polymer coatings hereinafter will be designated as polymer coating. Barbed wire strand wire, produced from three classes of wire coatings, is covered as follows: class 1 - polymer coating extruded over zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; class 2a - polymer coating extruded and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; and class 2b - polymer coating fused and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire. Polymer-coated steel barbed wire is supplied in a choice of two types as follows: type I - standard, and type II - high security. Breaking strength of the stranded barbed wire shall be tested to meet the requirements prescribed. Adhesion test, accelerated aging test, and color test shall be made to meet the requirements prescribed.

This specification establishes the criteria for polymer privacy insert slats designed for insertion into chain link fabric after the chain link fence installation and privacy chain fabric having slats preinserted into chain link mesh during the chain link weaving process. It covers four types of polymer privacy insert slats: Type P-V consisting of polyethylene privacy insert slats hand inserted vertically into standard mesh chain link fabric after the fence installation; Type P-D consisting of polyethylene privacy insert slats hand woven diagonally into standard mesh chain link fabric after the fence installation; Type F-VDH consisting of modified fiberglass privacy insert slats hand woven, vertically, diagonally or horizontally into standard mesh chain link fabric after the fence installation; and Type PI-V consisting of privacy chain link fabric with vertical high density polyethylene privacy slats pre-inserted into the chain link mesh during the chain link weaving process. The standard addresses ordering information, privacy slat design configurations, weathering, chain link fence framework, tie wires and hog rings, and installation.

This specification covers barbed tape materials and configurations used for security barriers. Barbed tape shall be manufactured from stainless and galvanized steel. Stainless steel strip shall be either ferretic or austenitic. Coil loops shall not be kinked, unless it is part of the design.

This specification establishes the requirements for copper-beryllium alloy (Copper Alloy UNS Nos. C17200 and C173002) wires in coils, spools, or other forms except straight lengths, of any uniform cross section. Products shall be available in the following tempers: solution heat-treated TB00, and cold-worked TD00 to TD04, which shall be precipitation heat treated after forming. Products that are already precipitation heat treated by the manufacturer shall be available in tempers TF00 (AT), and TH01 to TH04. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, thickness, length, width, and straightness), mechanical (tensile and bend strength, Rockwell hardness, and elongation), physical (grain size and count), and chemical composition requirements.

This practice covers the precautions that should be taken to obtain high-quality galvanized coatings. Assemblies should consist of elements of similar chemistry and surface condition. Whenever different analyses of steel or different surfaces of steel are united in an assembly the galvanized finish is not generally uniform in appearance. These differences include excessively rusted surfaces, pitted surfaces, machined surfaces, cast iron especially with sand inclusion, cast steel, malleable iron, hot-rolled steel, and cold-rolled steel. All oil or grease should be removed from both the sheet steel and wire or rod before rolling. Welding flux residues shall be removed by standard galvanizing cleaning techniques and are best removed at the gun. All fabricated assemblies shall be so designed with vent and drain holes such that no air is trapped during immersion of the assemblies into cleaning solutions or molten zinc. Moving parts such as handles or hinges should be galvanized separately and assembled after galvanizing. All markings shall remain legible after galvanizing. When an assembly of steel parts or an individual steel part has been designed and fabricated with critical dimensions and must be subsequently hot-dip galvanized, the designer should be aware that the hot-dip galvanizing process chemical cleaning to prepare the surfaces for coating and this may alter the critical dimensions.

This specification covers the chemical, mechanical, and metallurgical requirements for wrought titanium-12 molybdenum- 6 zirconium-2 iron alloy for surgical implants to be used in the manufacture of surgical implants. The heat analysis shall conform to the chemical composition requirements prescribed. Ingot analysis may be used for reporting all chemical requirements, except hydrogen. The wrought titanium-12 molybdenum-6 zirconium-2 iron alloy are classified as bar, forging bar and wire. The ultimate tensile strength, yield strength, elongation, and area reduction of the material shall be tested to meet the requirements prescribed.This specification covers the referee test methods for evaluating the performance characteristics of a single-use ureteral stent with retaining means at both ends, during short term use for drainage of urine from the kidney to the bladder. Ureteral stents shall be tested in accordance with the appropriate biological tests to meet the requirements prescribed. Retention strength, break strength, elongation, dynamic frictional force, and radiopacity shall be tested to meet the requirements prescribed.

This specification covers the requirements for electrodeposited tin coatings applied to metallic articles to provide a low contact resistance surface, to protect against corrosion, to facilitate soldering, to provide anti-galling properties, and to be a stop-off coating in the nitriding of high-strength steels. This specification does not cover hot-dipped tin or other non-electrodeposited coatings, and mill products. Coatings shall be grouped into six service classes, which is based on the minimum thickness and severity of service required for the coating, and three surface appearance types, which is based on the type electroplating process employed. The surface appearance types are matte tin electrodeposits, bright tin electrodeposits, and flow-brightened electrodeposits. Coatings shall be sampled, tested and conform accordingly to specified requirements as to appearance, purity, local and mean thickness, integrity (including gross defects, mechanical damage, and porosity), adhesion, solderability, and hydrogen embrittlement relief.

This specification covers hot-rolled carbon steel sheet and strip, in coils and cut lengths. The cast or heat analysis of the steel shall conform to the chemical composition for copper, nickel, chromium, molybdenum, vanadium, and columbium. The bending properties are measured.
