PDIEC/TR62936:2016 IECTR62936:2016@IEC2016 -11- regulatory obligation that is placed on the supplier. Most severe in terms of regulatory impact would be prohibition or restriction of a substance in a product. The requirement to report the presence of a substance above a defined threshold limit without restricting the use of that substance in a product is deemed less severe (Criterion 2).No regulatory requirement for a substance is considered the least impactful and would score the lowest as defined by Criterion 3. An example of a Criterion 1 regulation would be RoHS which restricts certain substances to a defined threshold limit. REACH SVHC candidate substances would fall under Criterion 2 since these substances are not banned or restricted but do require reporting when present in the product above the defined threshold limit. 5.3.5 Intentionaladditionofsubstance This criterion is meant to capture those situations where a regulated substance is intentionally added to produce the final product. This substance is not a process chemical and its presence in the final product is expected. This criterion defines two situations where a substance is intentionally added: concentration is expected to be above threshold; concentrationis expectedto be below threshold. The unintentional presence of a substance in the final product may result from contamination, byproductformationduringprocessingandmanufacturingincompletechemicalreactionsor anyothersituationwherethepresenceof thesubstance wouldnotnormallybeexpected above threshold. NOTE For substances that are not regulated, the threshold of the potentially applicable regulations and requirements could be used for scoring 5.3.6 Strategic considerations This criterion is in place in order to identify substances that are expected to have a regulatory impactatsometimein the future.Earlyidentification of these substances will allowtime for development of test method standards hopefully in advance of the regulatory requirements being placed in force.In essence,thislist of substances could constitutearoadmap for strategic planning of activities for TC 111. It shall be noted that the attempt to predict which substances will be important from a regulations perspective is inherently risky.A substance may be considered as a strong candidate for future regulation today but over time may lose that importance due to a variety offactorssuchasvoluntaryphasingoutoftheuseofthatsubstance.newdataorevidence that altersthe hazard profile of that substance,alternatives that encouragetheeliminationof a substance used in a product, etc.There is no guarantee that a substance that is rated high IEc Criteria 3 substances are not currently regulated or under any defined timetable for regulation. Because the process for placing a substance under regulation is generally in the order of years, there may be sufficient time to develop an analytical test method prior to the regulationgoingintoforce.Substances thatare classified asiECCriteria2wouldalsoqualify if the lead time for the enforcement of the regulation of those substances is sufficiently long, i.e. several years or more. Substances that qualify under this criterion are expected to exhibit the following attributes: industry accepted test method standard not available and not currently under development; widely used in electrotechnical equipment; will be important for new or emerging market (e.g. wearables); very high likelihood that the substance will eventually move to IEC Criteria 1. A more detailed description of the attributes is given below. PDIEC/TR62936:2016 - 12 - IECTR62936:2016IEC2016 Test method standard not available - since the substances under this category are not currently regulated,it is very likely that the industryaccepted test method standard is not available or under development.Therefore,there is a gap and meanwhile this is an opportunity for an IEC test method standard to be developed. Widely used in EEE - the definition of “widely used" is s
