Requirements and Recommendations

The requirements and recommendations herein apply to all types of welding including tack welds, repair welds, and seal welds of threaded joints. 

Required and recommended minimum preheat temperatures for materials of various P-Nos. are given in Table 12.2. If the ambient temperature is below 0 °C (32°F), the recommendations in Table 12.2 become requirements. The thickness intended in Table 12.2 is that of the thicker component measured at the joint. 

Preheat requirements for an unlisted material should be specified in the Welding Procedure Specification (WPS). 

Preheat temperature should be checked by use of temperature indicating crayons, thermocouple pyrometers, or other suitable means to ensure that the temperature specified in the WPS is obtained prior to and maintained during welding. 

Thermocouples may be temporarily attached directly to pressure containing parts using the capacitor discharge method of welding without welding procedure and performance qualifications. After thermocouples are removed, the areas should be visually examined for evidence of defects to be repaired.

Because the ASHRAE/IES standard contained both mandatory requirements and recommendations, it was difficult to adopt and implement as a uniform building code. Such codes must clearly state minimum requirements that can be uniformly interpreted and applied. For this reason it was determined that a model code was needed that contained only the... 

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. 

Anmunition Plant. In the analysis, the probability levels of Table VI were used as requirements, and recommendations for changes made to subsystems which did not meet these requirements. 

Environmentally safe destruction of obsolete chemical weapons must be performed In facilities which assure total containment of blast effects and toxic gas In the event of an accidental detonation. Functional process requirements and recommended structural design procedures for containment rooms to accomplish this purpose are presented. The requirements presented are consistent with Department of the Army and Department of Defense Explosive Safety Board requirements. 

This chapter defines the terms, responsibilities, requirements and recommended procedures involved in pre-installation, installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ), which are all part of a typical HPLC system validation process. As the FDA does not publish a definitive reference or cookbook for these procedures, the suggestions herein are only recommendations. These have been successfully incorporated into formal standard operating procedures (SOPs) that have been implemented at a number of larger pharmaceutical establishments. As long as proper SOPs... 

Policy upon completion of each stage (DQ, IQ, OQ, PQ), a document review or report detailing results compared against the requirement and recommendations for future work must be prepared and accepted by appropriate management before proceeding to the next stage of validation or implementing the process. 

Note that since an ANDA is intended to reference and incorporate the research findings (safety and efficacy) of the original product applicant, other specific issues may arise depending upon the details of that original NDA. ANDA applicants should carefully review the requirements and recommendations of the NDA and/or the 505(b)2 NDA in preparation for the ANDA.

During fermentation, purification of the bulk active protein residual metal ions could be present as it contacts stainless steel, iron or copper surfaces. The use of a chelating agent is a requirement, and recommended dosages may range from 0.01 to 0.05% to bind or chelate the metal ions present in the solution. 

Note as in vivo bioequivalence trials are considered as clinical trials, specifically as a phase I study, the general requirements and recommendations of GCP apply to all bioequivalence trials. Clinical trials must be carried out under conditions which ensure adequate safety of the subjects. The clinical phase of the study can be performed in the premises of a CRO or in suitable premises in a hospital.
