Table III.B-three of the action contains the 2023 projected normal and optimum structure values and 2021 structure values and 4th high Begin Printed Web site 9351 MDA8 ozone concentrations and preliminary 2020 style and design values and 4th large MDA8 ozone concentrations for checking web-sites discovered as violating check routine maintenance-only receptors. The look values for all monitoring web pages while in the U.S. are offered from the docket for this action. Added details around the approach for projecting typical and optimum style values are supplied within the AQM TSD.

Incorporating take a look at methods including torque and tensile tests for areas of a shopper product that can be gripped by a Kid's fingers or enamel, or perhaps a tensile examination for pliable products, decreases the probability of kids gaining usage of button cell or coin batteries. Based upon employees's evaluation of such check strategies while in the ASTM F963 toy normal, the Commission decides that their inclusion in UL 4200A-2023 sufficiently assessments the durability and integrity of battery compartments in merchandise with pliable components, such as shirts and greeting cards that light-weight up or make sound utilizing batteries.

Which is, the contributions within the “biogenic” and “fires” classes are not assigned to individual states nor are they included in the state contributions.
