Compliance Assurance System
(CAS)
• A definition of the purpose of the system,
its essential requirements and
specification. This specification should
cover compliance both within the company
and within the supply chain
Compliance Assurance System
(CAS)
• A formally defined process which
implements the requirements of the
system and is integrated within the
organization’s quality and management
systems
Compliance Assurance System
(CAS)
• A technical documentation system (paper
and/or electronic) to support the process
and measures to assure conformity with
the requirements of the system together
with necessary training, tools and
infrastructure.
Evidence of Active Control of the
CAS
• Results of internal and supplier audits to
validate Compliance Assurance System
and/or processes. i.e. the supplier’s ability
to assure compliance.
Evidence of Active Control of the
CAS
• Evidence that the system is being followed
including results of product specific
conformance assessments comprising
items such as product assessments
(including justification of RoHS
categorization and use of exemptions),
materials declarations, procurement,
inventory and production controls and
substance analysis where appropriate
Evidence of Active Control of the
CAS
• Overview of any internal data system used
for the management of RoHS compliance
data
Evidence of Active Control of the
CAS
• Producers’ or suppliers’ completed
materials declaration for each part
(including revision for revised parts) and
justification of RoHS categorization and
use of exemptions. These declarations
would be limited to the list of RoHS
substances, not full materials declarations
Evidence of Active Control of the
CAS
• Analysis report for homogeneous
materials in parts/components, (which
could be the producers or suppliers own
internal or external test results). The test
results should refer to homogenous
materials in parts/components.
Evidence of Active Control of the
CAS
• Producers’ or suppliers’ warranties
/certificates declaring that the use of the
restricted substances is within the
permitted levels
Evidence of Active Control of the
CAS
• Provide evidence that procedures are
being followed to show that materials
declarations have been assessed to
determine if they can be trusted.
Enforcement authorities will also need to
see documented compliance procedures

(RoHS) Directive
IPC 1065
ANNEX B: Level B Materials and Substances
For Level B materials and substances, the default threshold level is 1000 ppm based upon the weight of the product
or subpart being declared. Reporting below the threshold is allowed, but not required.
Where metals are listed in Annex B, they require reporting of the metal content in the metal alloys..
Note: Materials/substances are listed by group. Please refer to Annexes E and F for details.

Threshold level
Antimony/Antimony Compounds

Certain Phthalates (see Annex F)

(Disclosure is limited to “is present”/”is not present” in
amounts that exceed threshold)
1000 ppm
1) Nickel alloys are not reportable. Nickel and nickel compounds must be reported when used in applications where nickel
compounds are likely to result in prolonged skin exposure (e.g., an outer enclosure for a portable electronic product designed to
be carried). Use of nickel or nickel compounds in components and parts designed to be located inside the outer enclosure of a
product need not be reported.
Homogeneous material
-Semiconductor package contains six
different homogeneous materials.
The term “homogeneous” is understood as “of uniform composition throughout”.
Examples of “homogeneous materials” are individual types of: plastics, ceramics, glass,
metals, alloys, paper, board, resins, and coatings. The Commission further states that a
“homogeneous material” cannot be mechanically disjointed into different materials.
The term “mechanically disjointed” means that the materials can be, in principle,
separated by mechanical actions. This means that an insulated wire is considered as
two homogeneous materials: the metal wire and the plastic insulating material.
