Measurement of test substance Sample Clauses

Measurement of test substance. (A) For static tests, the concentration of dissolved test substance (that which passes through a 0.45 micron filter) shall be measured in each test chamber at least at the beginning (zero-hour, before gammarids are added) and at the end of the test. During flow-through tests, the concentration of dissolved test substance shall be measured in each test chamber at least at 0 and 96- hours and in at least one chamber whenever a malfunction of the test substance delivery system is observed. (B) The analytical methods used to measure the amount of test substance in a sample shall be validated before beginning the test. This involves add- ing a known amount of the test sub- stance to each of three water samples taken from a chamber containing dilu- tion water and the same number of gammarids as are placed in each test chamber. The nominal concentrations of the test substance in these samples should span the concentration range to be used in the test. Validation of the analytical method should be performed on at least two separate days prior to starting the test. (C) An analytical method is not ac- ceptable if likely degradation products of the test substance give positive or negative interferences, unless it is shown that such degradation products are not present in the test xxxxxxxx during the test. (D) Among replicate test xxxxxxxx, the measured concentrations shall not vary more than 20 percent. The meas- ured concentration of the test sub- stance in any chamber during the test shall not vary more than plus or minus 30 percent from the measured con- centration in that chamber at zero time. (E) The mean measured concentra- tion of dissolved test substance shall be used to calculate all LC50’s and to plot all concentration-response curves.

  • Substance Abuse Testing The Parties agree that it is in the best interest of all concerned to promote a safe working environment. The Union has no objection to pre-employment substance abuse testing when required by the Employer and further, the Union has no objection to voluntary substance abuse testing to qualify for employment on projects when required by a project owner. The cost and scheduling of such testing shall be paid for and arranged by the Employer. The Union agrees to reimburse the Employer for any failed pre-access Alcohol and Drug test costs.

  • Temperature Measurement Temperature will be measured by the nearest automatic Melbourne Bureau of Meteorology Monitoring Station for example (but not limited to): Melbourne, Moorabbin, Dunns Hill, Melbourne Airport, Frankston, and Point Xxxxxx. At the commencement of each project, the onsite management and employee representatives shall agree which is to be the applicable automatic weather monitoring station.

  • Laboratory Testing All laboratories selected by UPS Freight for analyzing Controlled Substances Testing will be HHS certified.

  • Mileage Measurement Where required, the mileage measurement for LIS rate elements is determined in the same manner as the mileage measurement for V&H methodology as outlined in NECA Tariff No. 4.

  • Tests 7.7.1 If the Contract Documents, laws, ordinances, rules, regulations or orders of any public authority having jurisdiction require any portion of the Work to be inspected, tested or approved, the Contractor shall give the Architect timely notice of its readiness so the Architect may observe such inspection, testing or approval. The Contractor shall bear all costs of such inspections, tests or approvals conducted by public authorities. 7.7.2 If the Architect determines that any Work requires special inspection, testing, or approval which Subparagraph 7.7.1 does not include, he or she will, upon written authorization from the State, instruct the Contractor to order such special inspection, testing or approval, and the Contractor shall give notice as provided in Subparagraph 7.7.1. If such special inspection or testing reveals a failure of the Work to comply with the requirements of the Contract Documents, the Contractor shall bear all costs thereof, including compensation for the Architect's additional services made necessary by such failure; otherwise the State shall bear such costs, and an appropriate Change Order shall be issued. 7.7.3 Required certificates of inspection, testing or approval shall be secured by the Contractor and promptly delivered by him to the Architect. 7.7.4 If the Architect is to observe inspections, tests or approvals required by the Contract Documents, he will do so promptly.

  • HAZARDOUS SUBSTANCE CONDITIONS If a Hazardous Substance Condition occurs, unless Lessee is legally responsible therefor (in which case Lessee shall make the investigation and remediation thereof required by Applicable Requirements and this Lease shall continue in full force and effect, but subject to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor may at Lessor's option either (i) investigate and remediate such Hazardous Substance Condition, if required, as soon as reasonably possible at Lessor's expense, in which event this Lease shall continue in full force and effect, or (ii) if the estimated cost to investigate and remediate such condition exceeds twelve (12) times the then monthly Base Rent or $100,000 whichever is greater, give written notice to Lessee within thirty (30) days after receipt by Lessor of knowledge of the occurrence of such Hazardous Substance Condition of Lessor's desire to terminate this Lease as of the date sixty (60) days following the date of such notice. In the event Lessor elects to give such notice of Lessor's intention to terminate this Lease, Lessee shall have the right within ten (10) days after the receipt of such notice to give written notice to Lessor of Lessee's commitment to pay for the excess costs of (a) investigation and remediation of such Hazardous Substance Condition to the extent required by Applicable Requirements, over (b) an amount equal to twelve (12) times the then monthly Base Rent or $100,000, whichever is greater. Lessee shall provide Lessor with the funds required of Lessee or satisfactory assurance thereof within thirty (30) days following said commitment by Lessee. In such event this Lease shall continue in full force and effect, and Lessor shall proceed to make such investigation and remediation as soon as reasonably possible after the required funds are available. If Lessee does not give such notice and provide the required funds or assurance thereof within the time period specified above, this Lease shall terminate as of the date specified in Lessor's notice of termination.

  • Performance Tests Contractor shall perform Performance Tests in accordance with Section 11.2 of the Agreement and Attachment S.

  • Performance Testing (a) All performance tests of the Project, including any Initial Performance Test required in Section 2 of Appendix VIII, will be performed in accordance with the test procedures set forth in Appendix VIII (“Performance Test”), including additional procedures and protocols related to Performance Testing as mutually agreed between Buyer and Seller (“Test Procedures”). Seller shall bear all costs and receive all revenues, if applicable, associated with all Performance Tests. (b) After the Initial Delivery Date and during the Delivery Term, Buyer will have the right to conduct a Performance Test (“Buyer Performance Test”) no more than once a calendar year to demonstrate whether the Project is capable of delivering the Distribution Services at the Contract Capacity. Within 30 calendar days following a Buyer Performance Test, Seller will have the right to retest the Project with a Performance Test (“Seller Retest”). For the avoidance of doubt, the results of any Seller Retest will supersede the results of the preceding Buyer Performance Test. (i) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at or above ninety-nine percent (99%) of the Initial Contract Capacity, the Contract Capacity will remain the Initial Contract Capacity; (ii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at more than or equal to eighty-five (85%) of the Initial Contract Capacity, but less than ninety-nine percent (99%) of the Initial Contract Capacity (“Testing Band”), the Contract Capacity will be automatically adjusted (upwards or downwards) to the capacity commensurate with the amount of Distribution Services the Project delivered during the Performance Test within the Testing Band. (iii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is not capable of delivering Distribution Services of at least eighty-five percent (85%) of the Initial Contract Capacity, an Event of Default shall occur in accordance with Section 7.1(a)(viii).
