<strong>SS</strong>-<strong>00259</strong> (11th Edition) for General Use<br />
Substances: Lead and lead compounds<br />
(*) Test objects: plastics (including rubbers), paints, and inks<br />
Threshold level: Up to 100 ppm<br />
Standards for measurement<br />
1) Sample preparation<br />
Typical sample preparation methods: e.g. IEC 62321:2008, EPA 3052:1996<br />
(1) Closed system for acid decomposition method (e.g. microwave decomposition method)<br />
(2) Acid digestion method<br />
(3) Dry ashing method<br />
Note: Precipitates must be completely dissolved by some technical means (e.g. alkali fusion).<br />
Any extraction methods (including EN71-3:1994, ASTM F 963-96a, ASTM F 963-03, ASTM D 5517,<br />
and ISO 8124-3:1997) shall not be applied. Additionally, EN1122:2001 is not applicable for lead.<br />
2) Measurement methods<br />
Typical measurement methods: e.g. IEC 62321:2008<br />
(1) Inductively Coupled Plasma-Optical (Atomic) Emission Spectroscopy (ICP-OES [ICP-AES])<br />
(2) Atomic Absorption Spectroscopy (AAS)<br />
(3) Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS)<br />
Note: If a combination of a sample preparation method and a measurement method can ensure that the<br />
limit of quantification for lead is less than 30 ppm, the combination is applicable.<br />
Table 4.2a Allowable lead concentrations<br />
Type of alloy<br />
Steel<br />
Aluminum alloy<br />
Copper alloys (including<br />
brass and phosphor bronze)<br />
Solder<br />
Allowable lead concentration<br />
up to 3500 ppm (or 0.35 wt%)<br />
up to 4000 ppm (or 0.4 wt%)<br />
up to 40000 ppm (or 4 wt%)<br />
up to 1000 ppm (or 0.1 wt%)<br />
Note: A solder whose lead content is equal to or less than the threshold level of solder shown in<br />
"Criteria/threshold levels" shall be used if it is used for anisotropic conductive film (ACF) and<br />
anisotropic conductive paste (ACP) as a conductive material.<br />
