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) 3271 was
21、submitted to the formal vote; together with the voting report, circulated as document CECC (Secretariat) 3372, it was approved by CECC as EN 100015-2 on 29 July 1993.

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 areas where a relative humidity of less tha
26、n 20 % may be encountered. CAUTION: Although this standard does not include requirements for personal safety, 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
27、 covered by this standard. (Attention is drawn to the fact that electrical 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 reduce the effects of ESD All clauses in Secti
28、on 2 of Part 1 apply. Section 3. Labels, signs and marking All clauses in Section 3 in Part 1 apply. Section 4. ESD protected area (EPA) All clauses in Section 4 of Part 1 apply with the following exceptions. 4.3.1 General Modification Materials used within an EPA shall have the characteristics desc
29、ribed in clauses 4.3.2 to 4.3.8 of EN 100015-1 which shall be measured at the lowest and highest expected relative humidity values. For qualification tests, materials shall be conditioned for 72 h before testing. NOTE 1Suitable measuring methods for material parameters are given in EN 100015-1, anne
30、x A. NOTE 2Some protective materials have electrical properties which are very significantly affected by low humidity and may not be suitable for use in this environment. 4.4 Ionization Addition NOTEIonization may be especially important in low humidity areas owing to the reduced charge decay charac
31、teristics of materials. 4.5 Humidity 4.5.1 Modification In areas where there is a risk of a relative humidity below 20% being encountered, the requirements in 4.5.201 shall be followed. NOTELow relative humidity severely reduces the dissipation effectiveness of materials used in certain types of wor
32、k surfaces, packaging, flooring and clothing. 4.5.201 Addition The minimum and maximum expected relative humidity levels shall be clearly stated. All materials used shall be within the specified ohmic values (resistance to ground, surface resistivity and volume resistivity) and charge decay characte
33、ristics of Table 1 and Table 2 throughout the stated range of relative humidity values. Where no minimum value is specified or marked on the materials, adherence to EN 100015-1 only shall be assumed. Section 5. Protective packaging, marking and identification of ESDS All clauses in Section 5 of Part
34、 1 apply. Section 6. Purchase, receipt, storage and handling All clauses in Section 6 of Part 1 apply with the following exceptions. 6.2 Purchase Modification All procurement orders for components and items related to electrostatic special handling activities shall quote the requirements of this Par
35、t of EN 100015. Both packaging materials and packaging actions shall be covered by these requirements. All procurement personnel shall receive appropriate training, see 7.2 of EN 100015/1. 6.3.1 Modification All receipt EPA should meet the requirements in Section 4 of this Part of EN 100015. Section
36、 7. Training All clauses in Section 7 of Part 1 apply. Section 8. Quality responsibilities All clauses in Section 8 of Part 1 apply together with the following additions.
