1. Acceptance of the relevant documents and instructions
1.11 The person in charge of the profession shall submit the design and network diagram to the professional or department that provides the conditions, distribute them to relevant personnel, and establish a project file for the management department to consult. 1.1.2 The person in charge of the specialty shall ensure that all the accepted conditions must be reviewed and signed by the review personnel of the specialty or department that proposed the conditions.
1.1.3 The person in charge of the specialty shall regularly check the accepted documents to ensure that the relevant personnel use the latest version of the conditions (especially important when preparing the construction version). 1.1.4 The person in charge of the specialty shall manage and distribute all the accepted documents in accordance with the "Regulations on the Management of Design Materials of Professional Work Shoes" (HG20557.593). 1.2 Proposed conditions
[.2.1 The proposed conditions shall be managed by the person in charge of the specialty. The person in charge of the specialty must ensure that the proposed conditions have been reviewed and signed according to the planned guarantee procedures. 1.2.2 The person in charge of the specialty shall keep the original documents compiled by the specialty. 1.2.3 In addition to keeping the original in the archives, the person in charge of the specialty shall keep a copy of each and every version of the proposed document and send it to a single archive together with the drawings and materials. 1.2.4 The professional designer of the process system shall prepare the letters related to the project and send them to other professionals. Before sending them out, the professional person in charge shall directly check and sign on the documents. 1.2.S The professional person in charge shall review the documents according to the situation. 19
2 Responsibilities of each level
2.! The authority of the professional design of the process system at all levels is divided into three levels in order to ensure the quality. 2.1.1 Design and compilation
The design and compilation level shall be approved by the professional designer of the process system. 2.1.2 Proofreading
The proofreading level shall be approved by the professional designer with a higher level of professional knowledge and less work experience. The proofreading qualification shall be approved by the unit.
2.1.3 Review:
The review shall be conducted by the process system professionals with official review qualification approved by the entity. If necessary, the professional person in charge, laboratory director or chief engineer with review qualification shall be responsible (see the quality assurance review procedure for details) 2 Division of quality assurance work
For any calculation or document, one person is allowed to perform more than one quality assurance work. For example, a plan reviewer cannot be a designer, and a document reviewer cannot be a checker. 20
3.1.1 Design development report,
3.1.2 Engineering design basic number.
3.1.3 User regulations and surface opinions.
3 Design regulations
3.1 Acceptance conditions
3.2 Preparation, review and approval
3.2.1 Take the preparation of "Noise control design regulations reduction requirements" as an example to explain as follows: 3.2.1.1 "Noise control design regulations preparation requirements" shall be prepared by the professional noise control design personnel of the process system. 3.2.1.2 After the preparation of "Noise control design regulations preparation requirements", the professional person in charge of the process system shall send them to the technical management department and other relevant departments for registration.
3.2.1.3 After comprehensive review opinions from all aspects, the professional noise control design personnel of the process system shall sign on the document, and it shall be checked and signed by the review personnel. 3.2.1.4 "Noise control design regulations preparation requirements" shall be submitted to the design manager, and the design manager shall solicit user opinions, and then the original design personnel shall incorporate the correct opinions. .2.1.5 The director of the department or the chief engineer shall review the final document and confirm that all his correct opinions have been conveyed before signing. 3.2.1.6 The final "Noise Control Design Specifications" shall be sent by the professional person in charge to the design manager for approval and signature: When user confirmation is required, the design shall be sent to the end user for approval and signature, and then the design manager shall issue this document. 3.2.1 The design specifications for insulation, coatings and material control specified in the specification shall be confirmed by the professional review or audit personnel of the process system: The design specifications for containers, heat exchangers and special equipment professionals for the common material system in the device shall also be confirmed by the designated professional review or audit personnel of the process system: 3.2.3 The design specifications are important design documents, so modifications should be kept to a minimum. Most modifications are made through change notification. For any modification proposed by the process system professionals, the modification instructions shall be prepared and submitted to the user for record. 21
4 Calculation
The calculation of all process system professionals shall be based on the relevant methods and calculation formulas approved by the company (institute). When the above-mentioned books do not include the required information, the technical management department may organize relevant professionals to propose, collect the process system professionals, and the technical management department shall organize discussions, apply and approve them to ensure the quality of calculation work.
