contain constant terms or factors The value of these terms must be understood and may also require conversion (b) See IEEE/ASTM SI-10 for other conversion factors NOTES: (1) Relationships that are exact in terms of the base units are followed by a single asterisk (2) The factors are written as a number greater than and less than 10 with or fewer decimal places The number is followed by the letter E (for exponent), a plus or minus symbol, and two digits that indicate the power of 10 by which the number must be multiplied to obtain the correct value For example: 3.523 907 E−02 is 3.523

Through April 30, 2015 INTRODUCTION As a service to persons who use the RTP-1 Standard, the RTP Standards Committee renders interpretations of the requirements upon request The procedure for requesting an interpretation is described in Mandatory Appendix M-11 The interpretations include all replies that have been approved by the RTP Standards Committee in response to inquiries concerning interpretation of the Standard An interpretation applies either to the edition and addenda (if applicable) in effect on the date of issuance of the interpretation or the edition and addenda (if applicable) stated in the interpretation Subsequent revisions to the Standard may supersede the interpretation I-1 ASME RTP-1 INTERPRETATIONS NO Interpretation: 9-1 Subject: ASME RTP-1, 2013 Edition, Paras 7-800, M12G-530(a) and (c), Demonstration Vessels Date Issued: May 15, 2014 File: 14-531 Question: Must a fabricator seeking certification for both solid RTP and dual laminate vessels fabricate and test two demonstration vessels? Reply: Yes Interpretation: 9-2 Subject: ASME RTP-1, 2013 Edition, Para 6-930(d)(2), Proof Tests Date Issued: May 15, 2014 File: 14-751 Question (1): As the definition (Mandatory Appendix M-9) of an independent testing laboratory does not mention accredited or certified, is used throughout the Standard, and in some locations does not state that the independent testing laboratory be accredited or certified as in para 6-930(d)(2), laminator qualification and secondary bonder tests require that the independent testing laboratory be accredited or certified as stated in para 6-930(d)(2)? Reply (1): No Question (2): For the purpose of the demonstration vessel, if the RPE hired by the fabricator is the reviewer of the procedures, is the witness to the testing, and signs the test report, will this be accepted as satisfying the requirements of para 6-930(d)(2)? Reply (2): Yes I-2 ASME RTP-1 INTERPRETATIONS NO Interpretation: 9-3 Subject: ASME RTP-1, 2011 Edition, Figure 4-10, Bolting Size and Thread Type Date Issued: October 30, 2014 File: 14-286 Question: A user specification for a RTP-1 tank specifies bolting material but not size Does RTP-1 require the RPE to select the bolting size and thread type based on the user’s bolting material specification? Reply: Yes Interpretation: 9-4 Subject: ASME RTP-1, 2011 Edition, Table NM2-1, Bolting Size and Torque Date Issued: October 30, 2014 File: 14-287 Question: A user specification suggests bolt hole size and torque values but not bolt specification Does RTP-1 require the RPE to select bolting size and torque so flange allowable stresses are not exceeded? Reply: Yes Interpretation: 9-5 Subject: ASME RTP-1, 2011 Edition, Laminate Construction Date Issued: April 30, 2015 File: 14-282 Question: A user specification for an RTP-1 tank does not state the laminate composition for the structural layer Does RTP-1 require a certain laminate composition for a structural layer or thickness? Reply: No, as long as the laminate meets the requirements of Part I-3 INTENTIONALLY LEFT BLANK I-4 ASME RTP-1–2015
