Accordance with the standards GB/T 1.1-2009. Drafting Rules "Standardization Guide Part 1 standard structure and preparation of" given.
The standard proposed by China National Light Industry Council.
This standard by the National Standardization Technical Committee and the detergent surfactant (SAC/TC272) centralized.
This standard was drafted. China Daily Chemical Industry Research Institute, Xi'an opened meters Ltd., Guangzhou Blue Moon Industrial Co.,
Beijing Green Umbrella Chemical Co., Ltd., Beijing Daily Chemical Co. Reward.
The main drafters of this standard. Yao Chen, the Yan Fang, Yu Wen, Joan Ho, Zhang and Zhao Jianli.
The washing process includes washing and rinsing, the development of this standard is intended to guide the establishment of standard application side in a realistic laboratory conditions, can
Enough reproducible assessment of different test methods in detergent consumption of water washing, thus saving water detergent performance evaluation.
End of a washing process, usually based on the consumer determine the actual standard-based (hand washing), and its essence can be attributed to sensory index
determination. In the washing machine, the machine is more dependent on program design basis for determining the end of the wash is rinsed in water quality physical and chemical indicators
Changes made. Therefore, this standard recommends that a judgment be made from the end of the washing process sensory evaluation, physical and chemical aspects, a more
Objectively reflect the real situation of detergent applications.
Clothing detergent water consumption depends mainly on the effect of washing and rinsing products and product categories, use, washing habits, washing
Many environmental factors, temperature, water, equipment and so on, but there is the impact of the interaction between these factors, the best conditions for a group does not exist
But it can objectively reflect the true effect of washing detergent product composition of different types of detergent or the like, and therefore the provisions of a unified bar
Member, testing and evaluation of various detergent in water consumption may be related to the actual existence of large differences in the washing process, for product development and practical application
With a lack of guidance. As a guide, this standard for different products and use, made in the laboratory to try to establish how operators
The actual combined, can be relatively objectively reflect the real situation of the test cloth with water consumption of detergents and water-saving performance evaluation should follow the basic principles
The standard application side with the actual situation on this basis, detailed conditions and procedures, and establishing their own specific needs assessment test side
law. Evaluation guidelines established in accordance with this standard provides that two or more of the same amount of water and detergent - saving performance ratio
Comparing and judging possible.
Detergent decontamination effect can not be ignored is another performance for the detergent with good detergency and effective method is to add
A large amount of detergent formulations of the active ingredient, but the negative impact is the need to consume more water to rinse it in the wash fabric
The residue, it can be said saving water and detergent decontamination own unique pair of two conflicting factors. The standard focus is on saving water
Performance, and for assessing the performance of detergent decontamination detection method in accordance with other relevant standards published implemented.
Clothing detergent and water consumption of water-saving performance

1 Scope
This standard test for establishing clothing under laboratory conditions with a detergent and water consumption of water-saving performance evaluation methods, provides the basic principles,
The basis and manner, and the need to determine the conditions.
This standard applies to all types of water washing cloth with a detergent solution (not including soap products).
