1、Designation:F2675/F2675M13Standard Test Method forDetermining Arc Ratings of Hand Protective ProductsDeveloped and Used for Electrical Arc Flash Protection1This standard is issued under the fixed designation F2675/F2675M;the number immediately following the designation indicates the yearof original
2、adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is used to determine the arc rating ofhand protective pro
3、ducts in the form of gloves,glove materials,glove material systems,or other protective products designedto fit on the hand and specifically intended for electric arc flashprotection use as protective accessories for workers exposed toelectric arc heat flux values from 84 to 25,120 kW/m22 to 600cal/c
4、m2s.1.2 This test method will determine the arc rating of handprotective products made of materials which meet the follow-ing requirements for flame resistance:less than 150 mm 6 in.char length,less than 2 s afterflame and no melt and drip whentested in accordance with Test Method D6413 or receive a
5、reported 50%probability of ignition of a material or flam-mable underlayer(see definition of ignition50)by this method.1.2.1 It is the intent of this test method to be used for handprotective products which are flame resistant or which have anadequate flame resistance for the required hazard(see 1.2
6、).Non flame resistant hand protective products may be used asunder layers in multiple-layer systems or tested for ignitionprobability.1.2.2 It is not the intent of this test method to be used forglove materials,which have been tested by Test MethodF1959/F1959M as flat panels of material then sewn in
7、to handprotective products.Materials for hand protective products,which are not normally produced in flat panels or whichdisplay shrinkage making the material unacceptable to test onpanels,shall be tested using this standard.1.2.3 Rubber insulating gloves meeting Specification D120and leather protec
8、tors meeting Specification F696 are notcovered by this test method and are specifically excluded fromits Scope.1.2.4 Hand protective products tested by this method arenew and ratings received by this method may be reduced oreliminated by hydrocarbon loading(gasoline,diesel fuel,transformer oil,etc.)
9、,sweat,dirt,grease,or other contaminants.The end user takes responsibility for use of hand protectiveproducts tested by this method when contaminated in such amanner which could reduce or eliminate the arc rating of thehand protective products.1.2.5 Gloves tested by this method provide no protection
10、from electric shock.Insulated gloves for protection fromelectric shock are addressed under other standards includingASTM D120.This test method is designed to provide infor-mation for gloves used for electric arc protection only.This testmethod is not suitable for determining electrical protectivepro
11、perties of hand protective products.1.3 This test method is used to measure and describe theproperties of hand protective products in response to convec-tive and radiant energy generated by an electric arc undercontrolled laboratory conditions.1.4 The values stated in either SI units or inch-pound u
12、nitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This test method does not apply to electric
13、al contact orelectrical shock hazards.1.6 This standard shall not be used to describe or appraisethe fire hazard or fire risk of materials,products,or assembliesunder actual fire conditions.However,results of this test maybe used as elements of a fire assessment that takes into account1This test met
