Scope
GB/T 40093-2021 is the English-translated version of 变压器产品生命周期评价方法.
GB/T 40093-2021 sets out how to carry out a life cycle assessment of a transformer and how to report it.
It works as the product category rule under which transformer makers issue Type III environmental declarations according to GB/T 24025-2009, and covers the power transformers of GB/T 1094.1, whether supplied as final products or built into other equipment.
It defines the product description, the functional unit of one transformer with its rated capacity, voltage, frequency, phase number, cooling method and reference life, and the reference flow.
It covers losses in use, maintenance, end-of-life disposal and recycling, and the data, data quality and cut-off rules taken from GB/T 37552-2019, closing with the life cycle report.
It can also guide similar transformer products. It was issued on 21 May 2021 and has applied since 1 December 2021.

1 Scope
This Standard specifies the life cycle assessment and life cycle report of transformer products.
This Standard applies to the life cycle assessment of transformer products; transformer products make Type III environmental declaration in accordance with GB/T 24025-2009.
Note: According to GB/T 24025-2009, this Standard is a product category rule for transformer products to carry out type III environmental declaration.
The use of product category rules when making type III environmental declaration helps to ensure the credibility and comparability of life cycle assessment conclusions.
This Standard applies to the power transformers that are specified in GB/T 1094.1, including transformers directly supplied to end users (final products) and transformers as part of equipment (intermediate products). It can also be used as reference for other similar transformer products.

4 Product life cycle assessment
4.2 Product life cycle assessment scope
4.2.1 Functional unit
This Standard takes "1 transformer" as the functional unit; the description of the functional unit shall include, but is not limited to:
a) function of the product (that is, the service to the user);
b) rated capacity;
c) rated voltage;
d) rated frequency;
e) phase number;
f) cooling method;
g) reference life time (design life).
Note: For 1 three-phase dry-type distribution transformer, the rated capacity is 315 kVA; the rated voltage is 10/0.4 kV; the rated frequency is 50 Hz; the cooling method is AN/AF; the reference life time is 20 years. The reference flow of the corresponding functional unit includes:
a) reference product that realizes the functions described in the functional unit;
4.3.1.2.2 Maintenance requirements
If applicable, the maintenance frequency of the product and the parts and materials used for maintenance shall be stated.
4.3.1.3 End-of-life stage
The following processing links shall be considered for all elements of the life cycle and recorded in the life cycle assessment report:
a) product/material disposal process (energy recovery, landfill);
b) product/material recycling (reuse, recycling or energy recovery).
If the data processed at the end-of-life stage is not available, the transportation of end-of-life waste and the types of waste materials shall be considered.
4.3.2 Data unit
4.3.2 in GB/T 37552-2019 applies.
4.3.3 Data collection requirements
4.3.3 and 4.3.4 in GB/T 37552-2019 apply. […]
4.3.4 Data quality assessment
4.4 in GB/T 37552-2019 applies.
4.3.5 Cut-off criteria
4.5 in GB/T 37552-2019 applies. […]
