What are sparkless tools?
Basiaclly non sparking tools are tools that produce less or no spark while used in work place. Frankly speaking there is no tool which is non sparking. Exactly saying these are less spark producing tools made up of metal alloys like brass,
home tutor maths copper nickel alloy, aluminium bronze or copper aluminium alloy. According to the purpose of use these tools can be non sparking wrenches, non sparking hammers, non sparking spanners, non sparking screw driver. Or it can a set of various tools called non sparking tool kit.
IS 4595-1909 on non sparking tools has laid down specification for it. According to it non sparking tools should be made of non ferrous alloy so that these tools can be used in atmosphere having flamable substance like flamable gases, dusts and explossives. Daman international and national manufactures these tools strictly according Indian Standard or IS 4595-1969. The standard says the alloy should have metals with following percentage:
Iron 3.5 % to 5.5%, Aluminium 8.5 to 10.5 %, NIckel 4.5% to 6.5 % , manganese maximum of 1.54%
All our tools with alloys containing various metal in the above mentioned range . Again the IS standard has put a following limitation on impurities:
Silicon 0.25%, Tin 0.1%, lead 0.05% and magnesium 0.05%
Daman takes utmost care not exceed impurites limit mentioned above. The total content of impurities lies well below 0.3% confirming to IS 4595-1969
The material used in making non sparking tools have minimum tensile strength of 70 kgf/square mm, which is mentioned in Indian standard. All tools do have hardness in the range of 190 to 230 HV.
Why lower tensile strength and what is its impact ?
All non sparking tools such as non sparking wrenches, non sparking hammers, non sparking spanners, non sparking screw driver. Or it can a set of various tools called non sparking tool kit do have lower tensile strength. Lower tensile strength than steel produces less spark and less tearing apart when in use so serves its purpose. This makes the tool softer than tools made of steel. But at the same time life of the tool is reduced and need more maintenance. The non sparking tools need to be dressed up in regular interval to work efficiently.
Do non sparking tools produce spark ?
Exactly speaking they produce spark which can be called as cold spark. Wondering, what is cold spark? The cold spark is a spark which can’t ignite the lowest combustible substance like carbon disulphide. So even though it produces little bit of spark still it is non hazardous in the atmosphere of flammable gas or dusts.

The sample is tested for all the quality mentioned in IS 4595-1969. math tutor near me The lot is accepted if the number of defective item is found below the number mentioned by Indian standard. The following table shows acceptable number of defective item in the sample.
