This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities....
1.1 This test method covers a procedure for experimentally determining macroscopic residual stress tensor components of quasi-isotropic bearing steel materials by X-ray diffraction (XRD). 1.2 This test method provides a guide for experimentally determining stress values, which play a significant...
FOREWORD On 24 June 1982, the aviation community and much of the world learned of the drama involving a British Airways B747 aircraft which lost power on all four engines while flying at 11 300 m (37 000 ft) from Kuala Lumpur, Malaysia to Perth, Australia. During the ensuing sixteen minutes, the...
This specification covers magnesium alloy permanent mold casting. The castings may be subjected to the heat treatment necessary to produce material that will conform to the requirements specified. Heat treatment shall be performed on the whole of a casting, never on a part only, and shall be...
This specification covers untreated and heat-treated steel closed-impression die forgings for general industrial use. The Grades of forgings are as follows: Grades CA, CC, CC1, CE, CF, CF1, CG, AA, AB, AC, AD, AE, AF, AG, and AH. These Grades shall be annealed, normalized, tempered and quenched....
General. This standard applies to all operations in fixed location abrasive-blast enclosures in which an abrasive forcibly comes in contact with a surface by pneumatic or hydraulic pressure or by centrifugal force. It does not apply to steam blasting, steam cleaning, or hydraulic...
1.1 This test method covers determination of the abrasion resistance characteristics of concrete by subjecting it to the impingement of air-driven silica sand. It is intended for use as a basis for the development of informed judgment. 1.2 The values stated in SI units are to be regarded as...
This standard describes the materials and equipment used for abrasive blast cleaning the inside of ferritic piping and it defines the different levels of surface cleanliness, which can be achieved. Other mechanical cleaning methods such as brushing, grinding, chipping, sanding, etc.,...
