"Instructions for Compiling Enterprise Product Standards" Writing Instructions
1 Purpose
According to the provisions of the "Guangdong Provincial Enterprise Product Standard Registration Management Measures", the "Enterprise Product Standard Preparation Instructions" is a necessary document for enterprise standard registration. It plays an important role in understanding the background and basis of standard formulation and ensuring the quality of standards. In order to do a good job in the registration and management of enterprise standards and unify the requirements for the preparation of "Enterprise Product Standard Preparation Instructions", this work guide has been specially prepared.
2 Content Requirements
2.1 Background and necessity of standard formulation
2.1.1 Whether there is any relevant product for the enterprise standard being applied for National standards, industry standards or local standards. If there are relevant national standards, industry standards or local standards that can be referred to, it should be stated which standard is referred to, the differences between the enterprise standard and the referenced national standard or industry standard, and the reasons;
2.1.2 If there are no relevant national standards, industry standards or local standards to refer to, you can refer to the following examples for expression.
Example: Background and necessity of standard formulation
Snow removal is an arduous task faced every winter in northern my country. Especially with the development of highway construction and the rise of expressways, traditional manual snow removal is far from being able to meet the needs. The snow cannot be removed in time, causing great difficulties to transportation. At present, in order to improve the efficiency of snow removal, we can only spray a large amount of salt. Salt is corrosive and is harmful to road surfaces, the environment and vehicles. To solve these problems. Our company has developed a new environmentally friendly snow removal agent - Ice and Snow Melt. This product is a patented product with low corrosivity, no environmental pollution, strong snow melting ability, and low cost. In order to ensure the production quality of this product, this standard is specially formulated. (For reference only, should be written according to the actual situation)
2.2 Implementation of current national standards and industry standards
2.2.1 If based on a current national standard, If it is formulated based on industry standards or local standards, it should be written which standard it refers to, and which contents of the enterprise standard are stricter than or equivalent to national or industry standards.
Example: This enterprise standard refers to GBXXX "XXX", in which the XXX index is stricter than the national standard, and the other indicators are the same as the national standard.
2.2.2 If there are no corresponding national standards or industry standards, the requirements of the national or industry standards in the relevant field for the limited indicators of the product should be stated.
Example: The "Three-in-One Milk Tea (Solid Beverage)" enterprise standard formulated by our company currently has no corresponding national or industry quality standards. In the formulation, it is based on GB 7101-2003 "Hygienic Standard for Solid Beverages" Based on the technical indicators of protein type, the requirements of item XX are stricter than the health standards.
2.3 The purpose and basis for determining the main technical indicators, test methods and inspection rules
2.3.1 The requirements for each indicator in the standard should be listed one by one. The basis, especially the direct reference to the content of a certain standard clause, should be pointed out if the specific standard number cannot be seen in the cited standard.
2.3.2 The basis for determining the factory inspection items and type test items in the inspection rules should be emphasized, and the others should be briefly explained.
Example:
(1) The purpose of formulating the technical requirements of this standard
1. As a quality basis for organizing production to ensure product quality.
2. Provide users with necessary technical instructions and guide them to use this product scientifically.
3. Facilitate statutory quality inspection departments to conduct notarized supervision and spot checks, and safeguard the legitimate rights and interests of users and enterprises.
(2) Basis for determination of main indicators
1. Determination of freezing point
Mainly based on actual snow melting needs and determined by actual measurements. .
2. Corrosion to asphalt pavement
If the snow removal agent is corrosive to the pavement, it is of little significance. It can remove snow without corroding the surface, which is the most ideal The product is formulated according to non-corrosive requirements, and there is no corrosion phenomenon through actual testing.
3. Corrosion to steel
The corrosivity to steel should also be extremely low and determined through actual measurements.
4. Keeping time
It has a preventive effect. It should be sprayed before snow falls and should be kept for a certain period of time after spraying. According to actual measurements, it is determined to be more than 3 days.
5. Dry matter concentration
Ice and snow melt is mainly composed of corn soaking liquid or corn steep liquor and one or more chlorides. According to actual needs and through experimental verification, it is determined that the concentration of M50 is not less than 35, the concentration of M20 is not less than 30, and the concentration of M10 is not less than 28.
6. PH value
Determined to be 1 to 4 based on actual measurements.
7. Viscosity
Determined based on actual measurement.
8. Test methods
The clauses refer directly to the certain standard number, and the certain clauses directly refer to the certain clauses and methods that implement the certain standard. Those that are not determined by ourselves.
9. Inspection rules
They are formulated in compliance with the requirements of certain national regulations and in combination with the actual situation of the enterprise.
2.4 Main reference standards and documents
List the standards and documents referenced in writing corporate standards and explain their current valid versions, including QS review rules, laws and regulations etc.
2.5 Other items that need to be explained (including comparison of standard levels)
The level of this standard (such as whether it reaches the international or international advanced, domestic advanced, industry advanced level) should be evaluated Evaluation, if there is no reference basis, it should also be explained.
If there are other matters that need to be explained, please also explain them here (such as additional technical requirements to meet the requirements of the production license review details, etc.).
