Standard Practice for Data Recording the Procedure used to Produce Heat Butt Fusion Joints in Plastic Piping Systems or Fittings

SIGNIFICANCE AND USE
5.1 The Device record includes information about how the heat butt fusion joint was made (heater temperature, pressures and times for the heating, fusion and cooling steps) and other important information about the process, job, equipment used, etc. The Device record is compared to the specified heat butt fusion procedure parameters to determine if the procedure was followed correctly. For comparison purposes, a graph of time versus pressure is generated from the data record to show pressure changes that occur during the butt fusion process. Comparing the time versus pressure graph to the steps in the procedure helps determine that the procedure parameters were observed, (Note 1). (See Appendix X1.) These records may be downloaded from the device and stored.  
5.2 When used in conjunction with manually-operated machines, the Device records information about the procedure used, the operator, the equipment, and the piping material. The Device may capture photographs of the set up (alignment and cleanliness) as well as the completed fusion bead. These records may be downloaded from the device and stored.
Note 1: The Device cannot show all aspects of the heat butt fusion conditions (such as wind, cold weather, blowing dust and sand, etc.) and does not preclude periodic joint testing as described in the applicable fusion standard or procedure.
SCOPE
1.1 This practice specifies the data recording information that is recorded, when data recording equipment is used, on heat butt fusion joints in a plastic piping system in order to compare the procedure used in making the joint to the heat butt fusion joining procedure specified. This practice is suitable for use with all heat butt fusion joining procedures such as Practice F2620, Specification F3372, Specification F2945 international standards or other qualified procedures. This practice primarily applies to hydraulically operated heat butt fusion machines and can be utilized for documenting heat butt fusion joints completed with manually-operated fusion machines.  
1.2 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Installation of Aluminum and Stainless Steel Jacketing over Thermal Insulation on Pipe and Rigid Tubing

SIGNIFICANCE AND USE
5.1 This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). This standard is intended to provide a basic practice for installing these types of materials. Refer to Specifications C1729 and C1767 for information on the differences between aluminum and stainless steel jacketing and where each is considered for use.  
5.2 This practice is not intended to cover all aspects associated with installation for all applications, including factory and field fabricated pipe fitting covers.
Note 1: Consult the National Commercial & Industrial Insulation Standards (MICA), Guide C1696, the product manufacturer, and/or project specifications for additional recommendations.  
5.3 Metal jacketing is typically used on insulated piping located outdoors, including, but not limited to, process areas and rooftops. Metal jacketing is used indoors where greater resistance to physical damage is required, for appearance, for improved fire performance, or as otherwise preferred. Metal jacketing used outdoors serves the same functions as indoors and also protects the insulation system from weather.  
5.4 Metal jacketing is used over all types of pipe insulation materials.
SCOPE
1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). It does not address insulation jacketing made from other materials such as mastics, fiber-reinforced plastic, laminate jacketing, PVC, or rubberized or modified asphalt jacketing, nor does it cover the details of thermal or acoustical insulation systems.  
1.2 The purpose of this practice is to optimize the performance and longevity of installed metal jacketing and to minimize water intrusion through the metal jacketing system. This document is limited to installation procedures for metal jacketing over pipe insulation up to a pipe size of 48 in. NPS and does not encompass system design. This practice does not cover the installation of metal jacketing on rectangular ducts or around valves and gauges. It excludes the installation of spiral jacketing on cylindrical insulated ducts but is applicable to metal jacketing on cylindrical insulated ducts installed similarly to pipe insulation jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use.  
1.3 For the purposes of this practice, it is assumed that the aluminum or stainless steel jacketing is of the correct size necessary to cover the thermal insulation system on the pipe or rigid tubing while achieving the longitudinal overlaps specified in 8.2.2 and 8.3.2. The size of the aluminum or stainless steel jacket necessary to achieve this specified longitudinal overlap closure is a complex topic for which the detailed requirements are outside the scope of this practice. Achieving this fit is very important to the performance of the total insulation system. See Appendix X1 for general information and recommendations regarding this closure of aluminum and stainless steel jacketing installed over thermal pipe and rigid tubing insulation.  
1.4 The intrusion of water or water vapor into an insulation system will, in some cases, cause undesirable results such as corrosion under insulation, loss of insulating ability, and physical damage to the insulation system. Minimizing the movement of water through the metal jacketing system is only one of the important factors in helping maintain good long-term performance of the total insulation system. There are many other important factors including proper performance and installation of the insulation, vapor retarder, and ...
