Installation certificate

Electrical safety. Most common commercial instruments have been certified for electrical safety by an organization such as UL (Underwriters Laboratory), CE, or CSA (Canadian Standards Association). However, certain less common instruments or custom-built instruments may have to go through a certification process at the time of installation. Certification required for electrical safety may take time to complete. A protective shield or casing may be required for automated systems with robotic arms for sample manipulation, to protect operators. 

An Electrical Installation certificate should be used for the initial certification of a new electrical installation or for an alteration or addition to an existing installation. 

It is thought that the new inspection schedule introduced by the 3rd amendment to the 17th Edition for all new work will help electricians carry out the work in an organized and efficient manner. Tbe schedule of inspections must be appended to the electrical installation certificate and given to the customer or client upon completion. 

The electrical installation certificate of test results and a copy of the completed inspection schedule shall be issued to those ordering the work in the format given in Appendix 6 of the lET Regulations. 

There are three model forms recognized by BS 7671 for certifying and reporting on electrical installations the Electrical Installation Certificate, the Minor Works Certificate and the Electrical Installation Condition report. Appendix 6 of The lET Regulations contains model forms and I will summarize their use beiow. 

The lET Regulations require an Electrical Installation Certificate, including a record of the items that have been inspected and a copy of the results of testing, to be issued upon completion of a new building or additions and alterations to an existing building in order to verify the inspection and test results. 

The lET Regulations require a Minor Works Certificate to be issued instead of an Electrical Installation Certificate to verify the inspection and test results of a small or minor electrical installation. A minor or small electrical installation is described as one which does not include the provision of a new circuit. 

Testing, certification, and installation rules for reheving devices are extensive. Eveiy chemical engineer responsible for the design or operation of process units should become veiy familiar with these rules. The pressure-relief-device paragraphs are the only parts of Sec. TII, Division I, that are concerned with the installation and ongoing operation of the facility all other rules apply only to the design and manufacture of the vessel. 

Requirements for any employer of, or self-employed, persons to be members of the Council for Registered Gas Installers (CORGI). Individual gas fitters must possess certificates of competence.

Snhseqnent chapters cover installation considerations (Chapter 6), inspection and maintenance practices (Chapter 7), regnlations, standards, and codes, inclnding certification test protocols (Chapter 8), and some illnstrative examples (Chapter 9). Chapter 10 provides a snmmary of the present state-of-the-art and what other information and research is needed, followed hy appendixes, a glossary, and snggested additional reading. 

Pump tests are needed to establish the performance of a machine before delivery to the user so that contract conditions may be satisfied. They are also required to establish the health of the pump at intervals in its service life. When a new pump is delivered, the pump manufacturer will supply data required either as a set of performance points or a plot as a certificate of suitability. Ideally, the pump should be tested in the system configuration that it is intended to supply, but usually tests are performed in the test bay in a standardized manner laid down by national and international codes. When a pump is installed, a simple test may be performed to establish a performance point in a similar way to periodic tests to establish how the machine s performance is being affected. 

Development of a QA/QC certification system to assure that the installation has complied with the agreed standards and specifications... 

Validations fall into two types prospective and retrospective. In prospective validation (see flow chart in Figure 2) the validation is done in a sequential manner, involving installation qualification and operational qualification (IQ/OQ) of equipment (e.g., chromatography instrumentation or column hardware). Appropriate calibrations accompany the IQ/OQ. Process qualification, or PQ, involves formal review and approval of a PQ protocol, execution of this protocol, and issuance of a formal PQ report which includes data analysis and recommendations (i.e., approval/certification of the process). If the process is not approved, the report may recommend a redesign or redoing of the validation protocol and, in some cases, a return of the process to process development for further optimization. 

The following documents of the manufacturer can be used as part of this qualification Description and instruction manual, installation drawings and - instructions, test and take over-certificates, and soft ware documentation. It is recommended to list and specify all necessary documents and their format in the purchase order, as this reduces time and effort for the buyer as well for the seller. 

Through the use of this clause, the design time can be reduced and the problem of certification can be eliminated. It now becomes a matter of defining the problem to be solved, defining the environment, selecting commercially available equipment which is rated as compatible for the task, following the manufacturer s instruction for installation and verifying the cable characteristics. 

Proper installation is dependent on the existing explosion protection measures and on the corresponding isolation system to be used. This guarantees operability. In addition the application and installation remarks of the manufacturer as well as the limits of application in accordance with the Type-Examination Certificate are to be obeyed in every detail. In Table 23-15 the most frequently used isolation systems for explosion protection measures are summarized. 

The certification activities include a series of process documentation and qualification studies that start with the initial installation of a sterilization system and continue as process engineering changes or new or revised product introductions are required. Qualification activities comprise installation, operational, change, and performance phases. 

Having chosen the analytical instrument or system, Installation Qualification, IQ, should be carried out to ensure that the equipment works the way the vendor or manufacturer specifies it should. IQ should be performed in accordance with a written test protocol with acceptance criteria with certification from the installation engineer, who is suitably qualified. Full written records of all testing carried out should be maintained as well as ensuring that adequate documentation and manuals have been supplied. The latter should include any Health Safety information from vendor or manufacturer. 

The installed capacities for hydrotreating distillates are predominantly moderate-pressure reactors (up to 3 MPa). Typical conditions used in today s commercial processes are summarized in Table IV (7). In the U.S., the Clean Air Act mandated that low-emission fuels will have to be developed for future use. Industry responded quickly, and by 1994 typical diesel fuels in the U.S. contained 0.05% S, with average cetane numbers of 42 and 31-37% aromatics. California imposed stricter standards, requiring 0.05% S and a minimum of 48 cetane with an emission that did not exceed that of a 10% aromatic fuel. This is the present standard for California Air Resources Board (CARB) certification. Through the development of improved processing and additives that lower emissions, Chevron was the...
