• definition of organizational systems, roles and responsibilities for implementation of
• appropriate specification from planning and design functions to give appropriate inputs to the procurement functions with regard to supplier RSC;
• confirmation of an effective process for the evaluation and selection of parts and materials:
• a review of operational process requirements (e.g. lead and lead-free process line segregation).

5.2 Sources of informationldata
52.1 Data selection strategy
To ensure cost-effective flow of information, the producer should determine the likelihood of restricted substances being present for every material, part and sub-assembly included in the product.
Product evaluation for re5tricted substances may be based on a combination of several
sources of information:
• supplier information;
• analytical testing;
• manufacturing and assembling operations, including incoming supply, process and delivery control.
It may not be possible or necessary to directly test every material, part and sub-assembly of a given product and test results Only represent the status of the tested sample.
A combination of these information sources is generally needed. The likelihood of restricted substances being present in the product should be used to select the type and level of technical documentation that is required to confirm that restricted substance requirements are met.
The reasons for selecting the information sources should be documented and up to date.
5.2.2 Supplier information
For complex products, collection of supplier information avoids costly and repetitive testing of materials, parts and sub-assemblies. Collection of supplier information should follow industry standards, where available, to minimize supply chain impact and ensure consistent and cost- effective flow of information throughout the supply chain.
Types of documentation that may be obtained from suppliers include:
• supplier declaration of conformity or certificate of conformity from the supplier specifying the restricted substance content of the material, part, or sub-assembly;
• material declaration data sheet (provides information on specific substance content);

• analytical test results (see Clause 6 for limitations and recommended uses):
• signed contract specifying restricted substance content of material, part, or subassembly
• supplier audits and/or evaluation reports.
When using information provided by suppliers, the producer shall evaluate the information to ensure that it meets the requirements defined within the producers procedures, The requirements should be based on standards, where available. The producer should also ensure that those suppliers have implemented acceptable RSC. To determine an acceptable procedure for a supplier’s product, the producer should assess the likelihood of the procured parts or products containing restricted substances. The producer may judge this potential based on:
• material types used for the part and/or product and historical likelihood of restricted substances being present in these material types.
• Information provided by supplier.
• historical experience with supplier organization.
For material declaration data sheets, the list of declarable substances represented, the declaration definitions and assumptions and the data format should be considered for alignment with industry standards. When an organization’s policy requires the control of additional substances, these additional requirements should be communicated to the suppliers and should be considered In the evaluation of material declaration information.
When supplier information does not meet the producer RSC requirements, or if there is a likelihood that the procured product materials, parts and sub-assemblies contain restricted substances, the producer should consider obtaining additional supplier information, analytical testing or using alternate evaluation methods to meet the substance restriction requirements.
5.2.3 Analytical testing
Analytical testing techniques may be used to measure the concentrations of restricted substances in prepared samples. Specific testing techniques and sample preparation methods are generally required for different types of materials. Sampling and sample preparation are critical to the accuracy of analytical tests. Analytical testing of electrical and electronic parts and equipment should follow industry standards on sample collection, preparation and testing methods, where available.
