Unplasticized polyvinyl chloride (PVC-U) pipes. Dichloromethane resistance test method ICS 83.140.30 G33 National Standards of People's Republic of China Replacing GB/T 13526-1992 Hard polyvinyl chloride (P Vp CU) pipe Methylene chloride immersion test method Posted 2007-12-05 2008-09-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard replaces GB/T 13526-1992 "hard polyvinyl chloride (PVU-U) pipes methylene chloride immersion test method." Compared with GB/T 13526-1992 main changes are. --- By the sample length 100mm to 160mm (see 5.1); --- Heated sample was immersed 20min to 30min (see 7.3); --- In accordance with international standards, the tilt angle of the sample determined according to pipe wall thickness (see 5.2); --- The results of the determination to destroy or no damage, damage percentage calculated ramps and ramps in the circumferential direction to calculate the percentage of damage (see 8.2). This standard reference ISO /DIS9852.2006 (in English), and the technical requirements of ISO /DIS9852.2006 agreement. This standard Annex A, Annex B normative appendix. The standard proposed by China National Light Industry Council.

Hard polyvinyl chloride (P Vp CU) pipe Methylene chloride immersion test method1 ScopeThis standard specifies the hard polyvinyl chloride (PVC-U) pipe methylene chloride immersion test method. This standard as a fast production process quality control, in order to characterize the extent and plastics pipe uniformity. This standard applies to various uses of hard polyvinyl chloride (PVC-U) pipes. Principle 2 2.1 The PVC-U pipes cut to a predetermined length, according to the wall thickness of its end faces cut to a slant angle, in the sample Dichloromethane was immersed in a water bath (30 ± 1) min to test samples in the relevant product standard specifies the extent of the damage temperature. 2.2 Distilled water was added to make a thick seal layer is formed on the methylene chloride, to reduce evaporation to achieve the protective effect. After immersing the sample should be Seal layer disposed in dichloromethane dropwise to the surface of the sample was impregnated, dried and finally check whether the sample destructive.3 Reagents3.1 dichloromethane, analytical grade. Warning. dichloromethane low boiling point (40 ℃), at ambient temperature easily gasified. Further, methylene chloride absorption through the skin and eyes Income caused poisoning, when the operating liquid methylene chloride or impregnated samples have sufficient preventive measures. Vapor is also toxic, the maximum concentration allowed Xu limit of 100mL/m3 (ppm). Thus, the container should be kept dry and ventilated storage rooms and places as well as the sample. 3.2 distilled water.4 deviceThis standard uses the following instruments and devices. a) bevel cutting instrument; b) a glass or stainless steel container. the right size, under specified conditions capable of receiving one or more samples from the container at the bottom of 10mm Installed with a strainer, cover to limit evaporation of the liquid; c) thermostat. the thermostat unit with stirring, the temperature can dichloromethane cooled to a predetermined temperature, maintaining the temperature of the test solution (T ± 0.5) ℃ within the range; d) hood. fitted with ventilation systems.5 Sample Preparation5.1 interception as a sample from the pipe length of 160mm, should be cut perpendicular to the pipe axis, pipe wall thickness of the sample should be larger than the standard Specified minimum wall thickness of the sample. 5.2 bevel cutting should avoid the heat as much as possible. The samples along the entire thickness of the end face of a fall into a slope, the inclination angle to the pipe wall Thick determine the corresponding relationship between the two in Table 1. Table 1 Relationship between the pipe wall thickness and bevel angle ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13526-2007_English be delivered?Answer: Upon your order, we will start to translate GB/T 13526-2007_English as soon as possible, and keep you informed of the progress.
