# §721.10601. Lanthanum lead titanium zirconium oxide.

- (a) **Chemical substance and significant new uses subject to reporting.**
  - (1) **The chemical substance identified as lanthanum lead titanium zirconium oxide (PMN P-11-273; CAS No.** 1227908-26-0) is subject to reporting under this section for the significant new uses described in [paragraph (a)(2)](#a-2) of this section.
  - (2) **The significant new uses are—**
    - (i) **Protection in the workplace.** Requirements as specified in § [721.63 (a)(4)](/cfr/40/721.63.md?p=a-4), [(a)(6)(i)](/cfr/40/721.63.md?p=a-6-i), and [(c)](/cfr/40/721.63.md?p=a-6-c). The following National Institute for Occupational Safety and Health (NIOSH)-certified respirators with an assigned protection factor (APF) of at least 50 meet the requirements of [§ 721.63(a)(4)](/cfr/40/721.63.md?p=a-4):
      - (A) NIOSH-certified air-purifying, tight-fitting half-face respirator equipped with N100 (if oil aerosols absent), R100, or P100 filters.
      - (B) NIOSH-certified air-purifying, tight-fitting full-face respirator equipped with N100 (if oil aerosols absent), R100, or P100 filters.
      - (C) NIOSH-certified powered air-purifying respirator equipped with a loose-fitting hood or helmet and high efficiency particulate air (HEPA) filters.
      - (D) NIOSH-certified powered air-purifying respirator equipped with a tight-fitting facepiece (either half-face or full-face) and HEPA filters.
      - (E) NIOSH-certified supplied-air respirator operated in pressure demand or continuous flow mode and equipped with a hood or helmet, or tight-fitting facepiece (either half-face or full-face).
    - (ii) **Industrial, commercial, and consumer activities.** Requirements as specified in [§ 721.80(j)](/cfr/40/721.80.md?p=j) (piezoelectric ceramics for active and passive underwater acoustic systems).
    - (iii) **Release to water.** Requirements as specified in § [721.90 (a)(4)](/cfr/40/721.90.md?p=a-4), [(b)(4)](/cfr/40/721.90.md?p=b-4), and [(c)(4)](/cfr/40/721.90.md?p=c-4) (Where N = 8, and 8 is an aggregate of releases for the following substances: Lead strontium titanium zirconium oxide (PMN P-11-270; CAS No. 61461-40-3); Calcium cobalt lead titanium tungsten oxide (PMN P-11-271; CAS No. 1262279-31-1); Calcium cobalt lead strontium titanium tungsten oxide (PMN P-11-272; CAS No. 1262279-30-0); Lanthanum lead titanium zirconium oxide (PMN P-11-273; CAS No. 1227908-26-0); and Lead niobium titanium zirconium oxide (PMN P-11-274; CAS No. 56572-83-9)).
- (b) **Specific requirements.** The provisions of subpart A of this part apply to this section except as modified by this paragraph.
  - (1) **Recordkeeping.** Recordkeeping requirements as specified in § [721.125 (a)](/cfr/40/721.125.md?p=a), [(b)](/cfr/40/721.125.md?p=b), [(c)](/cfr/40/721.125.md?p=c), [(d)](/cfr/40/721.125.md?p=d), [(i)](/cfr/40/721.125.md?p=i), and [(k)](/cfr/40/721.125.md?p=k) are applicable to manufacturers, importers, and processors of this substance.
