ASME B107.1 pdf download.SOCKET WRENCHES, HAND (INCH SERIES).
4.5 Proof Torque
When tested as specified. tools shall withstand the proof torque specified in the applicable tables without failure or permanent deformation that might affect the durability or performance of the tools.
4.8 Nut End Socket Opening
Nut end socket openings shall be such as to ensure acceptance when gaged with gages conforming to ASME HlO7,l7M
4.7 Finish
4.7.1 Surface Roughness. All external surfaces shall he free from pits. nodules, forge flash, burrs. cracks, and other detrimental defects, The external forge flash shall he remcwcd to blend smoothly with adjacent surfaces. Maximum surface roughness values shall he determined by microinch (pin.) values. Determination of microinch values shall be taken on a representatise surface. Areas that arc ground and huffed. or otherwise finished by an equivalent method, shall have a coating finish as specified in para. 4.7.2 and have a uniform surface with a miisiinum roughness in niicroinchcs using a 0.030 in. roughness width cutoff on the surface mcasunng instrument as slated herein. All surface roughness values shall he rated as the arithmetical average. At least 50% of the outer longitudinal surface or major diameter shall be 30 pin, maximum. excej* for oxide or phosphate coated sockets. Except where knurled or grooved, the remaining extenor longitudinal socket surface shall he ISO pin, maximum. Oxide or phosphate coated sockets shall have a maximum roughness of ISO f.l.in. Definitions and nomenclature used herein can be found in ASME B46.I.
5.2.1 Application of Proof Torque. The proof torque shall he applied with a suitable torque-producing machine.
(a) Sockets. A dric cod test mandrel of suitable strength and coniplying with the dimcnsional requirements of the drive lang specified in ASME Bl07.4M shall be employed. The test plug shall be driven by any suitable manual or mechanical means. The socket shall be engaged on the end of a mandrel to a depth in accordance with tables herein. Means shall be pro. sided to maintain the mandrel Insertion depth.
(b) lh,iwrcai Sockets. Tests shall be made in the same nianner as specified in ta) above except thati means shall be provided to keep the park of the universal socket assembly on a common ask about which the torque Es applied.
5.2.2 Mandrels for Wrench Openings. Sockets shall be tested on mandrcls. Six-point or 12-point hexagonal sockets shall be tested on hexagonal mandrels. Four- or eight-point sockets shall be tested on square riundrels. The size of all mandrels shall conform to the tables herein, Mandrels shall he hardened to not less than 56 HRC.
5.3 CoatIng Process Qualification Test
The Coating Process Qualification Test for Alternate Coatings shall be performed to certify the manufacttwer’s production coating process. The Coating Process Qualification Test consists of an isdhcsioa. abrasion. and corrosion lcst specified in paras. 5.3.2. 5.3.3, and 5.3.4. The Coating Process Qualification Te.st may also be performed to certify the manufacturer’s Nickel- Chromium plating process. Passing the Coating Process Qualification tests, when agreed to by the customer. exempts the manufacturer from the Nickel-Chromium Thickness requircnwnt of para. 4.7.2(a) and the Nickel- Chromium Adhesion requirement of para. 47.2b).
Retcsting may he required when a signi&ant change occurs in the process. when there is a change in the materials, or when contractually required by the customer.
5.3.1 Test Preparation. The quanlity and condition of the sample sockets used for thc following testing shall be per the manufacturer’s standard practice or as mutually agreed to by the manufacturer and the customer.
