Plastic liners Sample Clauses

The 'Plastic liners' clause specifies requirements regarding the use, supply, or quality of plastic liners in a particular context, such as packaging, shipping, or waste management. It may detail the type, thickness, or environmental standards the liners must meet, and outline responsibilities for providing or disposing of them. This clause ensures that all parties understand their obligations concerning plastic liners, helping to prevent disputes over quality, supply, or environmental compliance.
Plastic liners. The tensile yield strength and ultimate elongation shall be determined in accordance with paragraph A.22 (Appendix A). Tests shall demonstrate the ductile properties of the plastic liner material at temperatures of -50 °C or lower by meeting the values specified by the manufacturer; The polymeric material shall be compatible with the service conditions specified in paragraph 4 of this annex. In accordance with the method described in paragraph A.23 (Appendix A), the softening temperature shall be at least 90 °C, and the melting temperature at least 100 °C.

Plastic liners. The tensile yield strength and ultimate elongation shall be determined in accordance with paragraph A.22. (Appendix A to this annex). Tests shall demonstrate the ductile properties of the plastic liner material at temperatures of -50 °C or lower by meeting the values specified by the manufacturer; the polymeric material shall be compatible with the service conditions specified in paragraph 4. of this annex. In accordance with the method described in paragraph A.23. (Appendix A to this annex), the softening temperature shall be at least 100 °C." 6.4. Test pressure The minimum test pressure used in manufacture shall be 30 MPa; 6.5. Burst pressures and fibre stress ratios For all types of cylinder the minimum actual burst pressure shall not be less than the values given in Table 6.3 of this annex. For type CNG-2, CNG-3 and CNG-4 designs the composite over-wrap shall be designed for high reliability under sustained loading and cyclic loading. This reliability shall be achieved by meeting or exceeding the composite reinforcement stress ratio values given in Table 6.3 of this annex. Stress ratio is defined as the stress in the fibre at the specified minimum burst pressure divided by the stress in the fibre at working pressure. The burst ratio is defined as the actual burst pressure of the cylinder divided by the working pressure. For type CNG-4 designs, the stress ratio is equal to the burst ratio. For type CNG-2 and CNG-3 designs (metal-lined, composite over-wrapped) stress ratio calculations shall include: (a) An analysis method with capability for non-linear materials (special purpose computer program or finite element analysis program); (b) Elastic-plastic stress-strain curve for liner material shall be known and correctly modelled; (c) Mechanical properties of composite materials shall be correctly modelled; (d) Calculations shall be made at: auto-frettage, zero after auto-frettage, working and minimum burst pressures; (e) Pre-stresses from winding tension shall be accounted for in the analysis; (f) Minimum burst pressure shall be chosen such that the calculated stress at minimum burst pressure divided by the calculated stress at working pressure meets the stress ratio requirements for the fibre used; (g) When analysing cylinders with hybrid reinforcement (two or more different fibre types), the load share between the different fibres shall be considered based on the different elastic moduli of the fibres. The stress ratio requirements for each individual f...

C8.64 – DEBARMENT AND SUSPENSION CERTIFICATION (3/18). Pursuant to 2 CFR 180 and 2 CFR 417, Purchaser shall certify and obtain certifications from its Subcontractors regarding debarment, suspension, ineligibility, and voluntary exclusion, including additional Subcontractors obtained after award of this contract. “Subcontractors” are participants in lower tier covered transactions. Purchaser may rely upon a certification of a prospective Subcontractor that it is not proposed for debarment under 48 CFR 9.4, debarred, suspended, ineligible, or voluntarily excluded from participating in covered transactions or timber sales, unless Purchaser knows that the certification is erroneous. Purchaser shall keep the certifications of its Subcontractors on file until timber sale Termination Date and any extensions thereof, and will provide a copy at the written request of Contracting Officer. Nothing contained in the foregoing shall be construed to require establishment of a system of records in order to render in good faith the certification required by this Subsection. The knowledge and information of Purchaser is not required to exceed that which is normally possessed by a prudent person in the ordinary course of business dealings. If Purchaser knowingly enters into a timber sale transaction with a person who is proposed for debarment under 48 CFR 9.4, suspended, debarred, ineligible, or voluntarily excluded from participation in covered transactions or timber sales, in addition to other remedies available to the Government, Forest Service may pursue available remedies, including suspension and/or debarment. Contracting Officer shall provide a copy of Forms AD-1047 Certification Regarding Debarment, Suspension and Other Responsibility Matters – Primary Covered Transactions and AD-1048 Certification Regarding Debarment, Suspension, Ineligibility and Voluntary Exclusion – Lower Tier Covered Transactions to the Purchaser. Purchaser shall complete form AD-1047 and provide to the Contracting Officer upon request. Purchaser shall require each subcontractor to complete form AD-1048 and provide to the Contracting Officer upon request.
