Purchase orders

Y = coefficient naving value in Table 10-50 for ductile ferrous materials, 0.4 for ductile nonferrous materials, and zero for brittle materials such as cast iron t,n = minimum required thickness, in, to which manufacturing tolerance must be added when specifying pipe thickness on purchase orders. [Most ASTM specifications to which mill pipe is normally obtained permit minimum wall to be 12V percent less than nominal. ASTM A155 for fusion-welded pipe permits minimum wall 0.25 mm (0.01 in) less than nominal plate thickness.] Pipe with t equal to or greater than D/6 or P/SE greater than 0.385 reqmres special consideration. 

For use in code piping at the stated allowable stresses, the tensile and yield strengths listed in these tables must be verified by tensile tests at the mill such tests shall be specified in the purchase order.

Drawings and data requirements for proposals and purchase orders shall be in accordance with Specification MD-0-JJOO3. 

Client s Inspector will check, as a minimum, equipment components, dimensions, connection sizes and locations, and quality of workmanship against certified drawings, data sheets, and purchase order documents. 

In addition to the Vendor s standard identification, tags shall be furnished to show the service, N P Refinery s tag number, and N P Refinery s order number for each tag item listed on the Purchase Order.

Flow-down provisions Terms and conditions which must be incorporated into a subcontract or purchase order to pass down obliga-tions/requirements imposed by the prime contract. These flow-down provisions will provide for certain protections, obligations, or requirements that will modify or add to any work agreement or purchase order terms and conditions. 

The regional contract administrators (purchasing department or others, depending on the structure of the organization) will provide the prime contractor flow-down provisions for incorporation into solicitation and subcontractors purchase orders. 

Only personnel who have completed the training prescribed by host organization health and safety personnel shall be allowed to work on host organization projects. Some projects may require contractor certification or special training as specified in the implementing purchase order. 

Signed copies of the work agreement or subcontract and implementing purchase order or contract... 

Production part approvals, tooling records, etc shall be maintained for the length of time that the part is active for production plus one calendar year, unless otherwise specified. This requirement, although removed, is implicit in the new requirement for record retention. However, the note on including purchase orders as quality records is removed, implying that they are not considered quality records but are documents and retained until obsolete. 

Not all instructions need to be documented - it depends upon the nature of the message being conveyed. Many types of forms have been conceived to convey instructions. Purchase Orders, Change Requests, Amendment Instructions, Engineering Orders, and Print Requisitions are all instructions that cause people to do work and hence are work instructions rather than procedures. 

The quality plan would be a logical place for such controls to be defined but clause 4.2.3 does not specifically refer to subcontractor controls. Any intention that they be defined in the quality plan is hidden in 4.2.3.1(b) where it requires you to give timely consideration to the identification and acquisition of any controls etc. Some companies produce a Quality Assurance Requirement Specification to supplement ISO 9001 and also produce a Subcontractor Surveillance Plan. In most other cases the controls may be defined on the reverse side of the purchase order as standard conditions coded and selected for individual purchases. 

In order that your subcontractors can achieve 100% on-time delivery, you need to provide the same type of information and make the same commitments as your customer will to enable you to meet 100% on-time delivery to them (see Part 2 Chapter 15). You therefore need to inform your subcontractors of your production schedule and release orders to your subcontractors based on that schedule. If operating under a ship-to-stock system, you will need a means of notifying your subcontractor when stocks drop to the minimum level. Under such arrangements, you do not need a purchase order for every delivery as one order specifying the shipment rate will suffice. A good maxim to work by is ... 

If you are procuring the services of a subcontractor to design and/or manufacture a product or service, you will need specifications which detail all the features and characteristics that the product or service is to exhibit. The reference number and issue status of the specifications need to be specified in the event that they change after placement of the purchase order. This is also a safeguard against the repetition of problems with... 

Prior to orders being placed the purchasing documents should be checked to verify that they are fit for their purpose. Again this requirement is appropriate to subcontracts but only if you submit your purchasing documents to your vendors. The extent to which you carry out this activity should be on the basis of risk and if you choose not to review and approve all purchasing documents, your procedures should provide the rationale for your decision. The standard does not require that the review and approval be documented. In some cases orders are produced using a computer and transmitted to the vendor directly without any evidence that the order has been reviewed or approved. The purchase order does not have to be the only purchasing document. If you enter pur-... 

Regarding purchases made by the supplier, there are three parties the ultimate customer, the supplier, and the supplier s supplier (the subcontractor). The standard has overlooked the fact that items are often inspected on receipt for conformance with the supplier s purchase order and not against requirements placed by the supplier s customer. Product may be nonconforming with the supplier s requirements but not the... 

Included in this element are requirements for purchasing documents (specifications, drawings, and purchase orders), selection of suppliers, inspection and control of received material and record-keeping. For ESH/PSM, this element would focus on those aspects of the procurement process which support purchasing according to regulatory requirements, safety standards, risk management controls, etc.

The following listing of data to be supplied to manufacturers when ordering motors or requesting bids is based on the requirements and recommendations of a number of representative manufacturers. This list is split into vital and desirable information and is intended as a checklist in preparing both requisitions and purchase orders. By using this list, you will give the manufacturer a clear picture of your needs for most motor applications in the oil and petrochemical industries and eliminate call-backs, requests for supplementary information, and so on. 

Do not mix special with standard motors on a single purchase order. If changes must be made later in specials, some delay can be avoided. 

Pipes shall be furnished in the sizes, wall thicknesses and weights as specified on the purchase order. (See Tables 4-142 to 4-145 for more detailed information on dimensions and weights of casing.)... 

Pipe shall be furnished in range lengths conforming to Table 4-147, as specified on the purchase order. When pipe is furnished with threads and couplings, the length shall be measured to the outer face of the coupling, or if... 

If so specified on the purchase order for round-thread casing only, jointers (two pieces coupled to make a standard length) may be furnished to a maximum of 5% of the order, but no length used in making a jointer shall be less than 5 ft. 

Couplings for pipe (both casing and tubing) shall be seamless and, unless otherwise specified on the purchase order, shall be of the same grade as the pipe, except grade H-40 and J-55 pipe which may be furnished with grade J-55 or K-55 couplings. 

The plant engineer should strive to make sure that, whenever possible, his purchase orders specify compliance with the correct standard. Many manufacturers can tmthfully claim that their specifications exceed the minimum requirements of a material standard, in which case they will have no objection to its inclusion in the order. Those who protest too much that its requirements are superfluous may deserve further scmtiny. Choosing the correct specification is not always easy, and requires expertise in the relevant field. This expertise is available from consulting engineers or from an inspection authority, who will also appraise the vendor s designs and, if required, will witness critical stages of constmction and test. 

A few computerized PLM schemes are dynamic systems and can be integrated into an overall maintenance management information system. These contain maintenance inventory and purchase order modules and go far beyond just another work order system . They provide the necessary information to control complex maintenance environments, thereby improving productivity and reducing operational costs. 

The formal document that accepts a customer order includes a delivery promise, method and time for payment, and identifies any exceptions to the terms and conditions stated on the customer s purchase order.
