19、dardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of
20、an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This European Standard was prepared by CECC WG ESD. The text of the draft based on document CECC(Secretariat)3272 was su

General 1 General 1.1 Scope This standard gives the additional requirements to standard EN 100015-1 for the protection of electrostatic discharge sensitive devices from electrostatic discharges in
26、areas where exposed energised conductors having a potential in excess of 1,25 kV a.c. or 2,5 kV d.c. may be encountered. NOTEIn this Part of EN 100015, higher series resistance values have been incorporated mainly to prevent additional risk to personnel. These higher resistance values will result in
27、 longer charge decay times. CAUTION: Attention is drawn to the need for all concerned to comply with the relevant local statutory requirements regarding the health and safety of all persons in all places of work including those covered by this standard. (Attention is drawn to the fact that electrica
28、l potentials in excess of 50 V a.c. or 120 V d.c. may be dangerous to personnel). 1.2 Definitions All definitions in clause 1.2 of Part 1 apply. Section 2. Design considerations to minimize the effects of ESD All clauses in section 2 of Part 1 apply. Section 3. Labels signs and marking All clauses i
29、n section 3 of Part 1 apply with the following modification. 3.2 Signs for ESD protected area (EPA) Modification Signs as shown in Figure 3 of EN 100015/1 shall be clearly visible to personnel before they enter the EPA. At least one sign shall be visible from all normal working positions within the
30、EPA. The signs shall contain all the elements shown in Figure 3 of EN 100015-1 with the words “high voltage” inserted between the first and second lines of the text. The incorporation within the sign of symbol 5036 of IEC Publication 417 is recommended. Signs shall have a minimum size of 300 mm 150
31、mm. Section 4. ESD protected area All clauses in section 4 of Part 1 apply with the following modifications. 4.1.1 General Modification The EPA shall be designed to ensure that ESDS can be handled with minimum risk of damage as a result of electrostatic fields or discharge. The EPA shall be construc
32、ted to ensure that the equipment used to control static electricity does not create any additional risk of electric shock to personnel, should energised conductors be exposed. CAUTION: The normal risk of electric shock is not precluded by the use of EPA fittings. NOTEEPA may take many forms includin
33、g the following: a) a bench; b) a store; c) an area of work; d) a field work area; e) a work station and equipment (e.g. solder flow machine). 4.1.2 Additional protection against exposed high voltages Modification In an EPA where exposed energised conductors exist, for each 250 V a.c. (500 V d.c.) p
34、otential, the minimum resistance of any working point to ground shall be 7,5 105ohm. 4.3.7 Wrist straps Modification A wrist strap shall consist of a band that fits snugly around the wrist and a cord to connect the band to an earth bonding point. The wrist strap shall be made with a quick release co
35、nnection with a preference for releasing at the wrist first in the event of an emergency. Licensed Copy: sheffieldun sheffieldun, na, Thu Oct 26 01:47:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 100015-4:1993 4 BSI 12-1998 1) The requirements of 4.3.7 1) of EN 100015/1 apply. 2) The connecting
36、cord shall be made of conducting cable covered with insulating material and provided with a means of compatibly connecting the cord to the earth bonding point, see 4.6.9 of EN 100015/1. The cord shall incorporate at least one insulated 1 106ohm (min. 9 105 ) current limiting resistor at the identifi
37、ed wrist end of the cord. The completed cord shall withstand a voltage test of 1,25 kV a.c. or 2,5 kV d.c. between the ends for each 1 106ohm for a minimum of 20 s. Materials that depend on their length to provide the minimum necessary resistance shall not be used. The resistance from the hand to th
38、e remote end of the cord shall be in accordance with 4.1.2. Where the wrist band cord uses the same type of connection for both wrist band and earth bonding point, the end of the cord containing the current limiting resistor shall be identified on the cord housing for the wrist band connection. The
39、maximum rated potential for which the cord is designed shall be identified on the cord. NOTEThe use of a safety isolating transformer is recommended when the handling of live parts can occur. 4.4 Ionization Addition NOTEIn areas where a personnel safety hazard may occur, or where national legislatio
40、n prevents the use of equipotential bonding of personnel, wrist straps and conductive or non-insulating flooring and footwear, the ionization as defined in EN 100015-1-4.4 may be used as the primary means of controlling the maximum work surface and space potential generation. 4.4.401 Addition Ionize
41、rs shall not be used within 300 mm of exposed high potentials. 4.6 Construction of the ESD protected area (EPA) 4.6.2 Modification All forms of EPA shall be constructed such that the materials used shall be electrically bonded together and have a minimum value of resistance to ground that limits the
42、 current to ground produced by voltages accessible to the operator to 0,50mA minimum, 0,67 mA maximum, see 4.1.2 and annex A.1.3 of EN 100015-1. The resistor chosen, together with all relevant insulation, shall withstand the maximum expected exposed potential without a decrease in resistance. NOTEPe
43、rsonnel movements in conjunction with working surfaces and flooring could result in parallel paths to ground. Caution shall be observed in the parallel paths to ground that could arise which may reduce the equivalent resistance of operators to ground to unsafe levels. 4.6.8 Earth bonding points Modi
44、fication 1) A dedicated earth bonding point for the wrist band cord shall be established adjacent to each working area, or working surface, such that it is easily accessible without obstructing the work in hand nor presenting a possible hazard in the working environment. NOTE 1The wrist strap may be
45、 connected to earth via the worksurface conductive element provided that the total resistance to ground does not exceed the value determined in clause 4.3.7 of this Part 4 of EN 100015. NOTE 2The earth bonding point may be connected to ground via the working surface earth grounding point. 2) The req
46、uirements in 4.6.8 2) of EN 100015-1 apply. 3) The requirements of 4.6.8 3) of EN 100015-1 apply. 4) The requirements of 4.6.8 4) of EN 100015-1 apply. 5) The requirements of 4.6.8 5) of EN 100015-1 apply. 6) The requirements of 4.6.8 6) of EN 100015-1 apply. 7) The requirements of 4.6.8 7) of EN 10
47、0015-1 apply. 8) The requirements of 4.6.8 8) of EN 100015-1 apply. 4.6.12 Electrostatic fields Replacement NOTEAppropriate shielding should be used to minimize the hazard of induced electrostatic fields.

49、apply with the following modification. 7.1 Modification Relevant structured training shall be provided for all personnel who specify, procure design, mark or handle ESDS in any way, or are likely to do so including those who manage and supervise them. Special emphasis shall be placed on the training of personnel who are to undertake field work and may be required to work in areas where high voltages are present. Section 8.
