Certification machines

This section covers only the tests that are essential on a completed motor, irrespective of the manufacturing procedure and stage quality checks. If ISO 9000 guidelines are assimilated, practised and enforced by a manufacturer so that a customer s trust is obtained, a final pre-despatch inspection by the customer may not be necessary. The customer, having gained confidence in the practices and Quality Assurance Systems of the manufacturer, may issue an authorization to the manufacturer to despatch the material under their own inspection certificate, rather than an inspection by the customer. We discuss below the test requirements procedure and the acceptance norms prescribed by various national and international standards for such machines and adopted by various manufacturers. [Pg.250]

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. [Pg.516]

Starting in 1995, a collaboration between Vivid Technologies and Gdardoni led to inclusion of real-time explosive detection in carry-on baggage machines. Heimann, EG G, and Rapiscan soon produced machines with this feature, which became known as operator assist. The FAA performed detection testing on such systems in 1997 and although the results were reasonably good, they did not meet certification... [Pg.107]

PLC-based systems are similar to solid-state systems. They nse the same field interface cards and have the same level of certification but the logic functions are performed by software. They are also easier to interface to other systems (via serial commnnications) in order to notify the system of a failnre. The PLC used is subject to rigorous source code (machine level) inspection and testing by an independent certification body (e.g., TUV in Europe) to examine the safety integrity of the code, inclnding all possible failure paths. The PLC system (application software and hardware) should be developed and tested using a formal, hfe-cycle methodology. ... [Pg.570]

Both materials, without pesticides (blank) and with pesticides (spiked samples), were bottled in amber glass vials using a fully automatic filling machine for powders. About 2.8 g of salt powder was introduced into each amber vials whose were closed and filling with 99.995% argon with teflon faced rubber lids, held in place with aluminium caps. The CRM 606 consists of a set of three samples one blank and two spiked pesticides, packed in a polyethylene bag. Additionaly 160 vials of spiked salt were available for the homogeneity, stability and certification exercise. [Pg.383]

A cyclotron is required to be registered with the state since it produces radionuclides. A dedicated PET scanner may or may not be required to be registered in a state depending on the state s statutes on this matter. Many states require a certificate of need (CON) prior to the purchase of a PET scanner, a mobile PET, or a PET/CT scanner. A PET/CT scanner is required to be registered with the state because of the CT unit, since all states require registration of radiation-generating machines. [Pg.157]

Craftsmen certificates are awarded after the successful completion of four years training. Two years of intensive training are spent on precision engineering skills embracing precision machining and tooling, and toolroom machining. This is followed by two years in-plant attachment in selected companies to hone the skills. [Pg.73]

Fabrication certification Once the certified material is obtained, the next step is fabrication where industrial processes such as machining, welding, and assembly are used to construct components, systems, and ships. OQE is used to document the industrial processes. Separately, and prior to actual fabrication of the final product, the facility performing the work is certified in the industrial processes necessary to perform the work. An example is a specific... [Pg.453]

The appointed person must sign the daily log certificate kept beside each machine which is an indication that the press is fit for use. Without the signed certificate, the press cannot be operated. [Pg.281]

Certification and approvals are statements by an impartial accredited body that a product or service fulfills specific requirements, such as directives and standards. Certification may be mandatory, as is the case for some regulated products (Annex IV machines, telecom, medical devices, etc.), or voluntary as Is the case for most product and machine categories. Manufacturers often seek voluntary certification to assure themselves, customers, and authorities that their products meet the requirements set by law. Certification is commonplace in Europe and allows the use of a distinctive approval mark affixed to the product that is backed by a certificate and test report. The approval mark, is a recognized quality mark attesting to a products conformity to the relevant requirements, such as for EMC and safety. [Pg.6]

Some people believe that the reason for the popularity of German safety approvals such as the GS Mark, is that approvals were mandatory in Germany. After all, over 100,000 different products bear the GS Mark (GS = Safety Tested). Approvals and marks have, however, never been mandatory by German law for the vast majority of products and machines. Their popularity is driven by expectations in the marketplace from the product users, consumer groups, insurers, and employers. These high expectations continue today in Germany and some other countries. (See chapters on Notified Bodies and Certification [Chapter 4] and the Quality and Safety Mindset [Chapter 5].)... [Pg.8]

Product-specific directives (type C). Product-specific directives apply to regulated products, such as telecom and medical, as well as other products where extreme hazards exist, such as machinery listed in Annex IV of 89/392EEC. Involvement of a EU body may be mandatory, but not in all cases. If the class or type of product is regulated by the directive, then a European body must assess it and issue a Type-Exam Certificate prior to CE marking. Product-specific directives cover machinery, pressure vessels, medical products, telecom devices, toys, and others. It is necessary to refer to the relevant directive to see whether the involvement of a EU-notified body is mandatory for the product or machine in question. lYpe C directives take precedence over types A and B directives and refer to them as needed. [Pg.17]

For most products and machines, the self-declaration process (module A) is possible. In practice the manufacturer performs the complete product assessment according to EU standards, issues the declaration, and affixes the CE marking to the product. A technical file or documentation must also be available on demand for national enforcement authorities. Keep in mind that this is an internal self-assessment process, a do-it-yourself approach, that results in issuance of the manufacturer s declaration of conformity and the CE marking (Figure 2-6). The buyer may demand proof of safety/EMC compliance in the form of a mark, certificate, or test report from a European notified or competent body. [Pg.29]

Mandatory certification. Most products and machines do not require mandatory certification. But in such cases, as with some high-risk machinery or when harmonized standards do not exist or are not applied in full, a type examination by a notified body is required. After successful testing, a Type-Exam Certificate for machinery or Certificate of Conformity for EMC is issued by the EU Body. The manufacturer then affixes the CE marking and issues a declaration of conformity. [Pg.31]

The equipment manufacturer takes complete responsibility for the end product or machine and the components it specifies. If no positive evidence exists (CE not considered), it is always prudent to perform all relevant component tests or select a different component so no questions arise (see Figure 6-1). Safety testing and certification of components should rest with the component manufacturer and not burden the company that purchases them, instead leaving it up to the product designer to only verify through positive evidence that the component complies with the relevant standard (see Figure 6-2). [Pg.91]
